Foreword
Whenwe started development ontheMPXG2Guitar Effects Processor andthe
MPX R1 MIDI Remote Controller, we knew we were designing for the most
discriminitatingguitarists — players whose tonal foundationis basedonthis no-
compromise equation:
great guitar + great amp = great tone
Our challenge was to put together a guitar effects system that could mesh with
your favorite gear and not get in the way of your signature sound. Since we had
no intention of trying to duplicate the “great amp” portion of the equation inside
of our effects processor, we needed to make the MPX G2 capable of putting
effects in two places at the same time — between the guitar and your amp (like
stomp boxes) or in your amp’s effects loop (like rack effects). Add to that the
challenge of getting the sounds right, and combining analog and digital effects
in a roadworthy package, and you’re definitely into something totally new.
So, here it is. A lot of people have put a lot of sweat into this box so you could
do what you do best — so get out there and play.
Throughout the development process of our Custom Shop products, we’ve
had the help of a team of artist advisors. Time and again their input had a
majorimpact onboththeMPXG2Guitar EffectsProcessorandMPXR1MIDI
RemoteController. Somewerewithusatthebeginning,whentheseproducts
were just concepts on paper, others joined us as various prototypes came
roaring to life.
Jon Finn, Dave Friedman of Rack Systems Ltd., Michael James, Eddie
Kramer,PeterMcCabeofToneKingStudio, JohnMcIntyre,BobbyOwsinski,
John Petrucci, Blues Saraceno, Alex Saraceno, David Torn and Carl
Verheyen — each made significant contributions, including:
putting their reputations on the line by working with experimental
gear in front of large paying audiences — or in critical sessions with
the clock ticking, so that we could evaluate under real-world condi-
tions.
sharing secrets, tips and tricks — “How did you get that sound on
(insert hit tune from platinum record)?”
spending hours and hours of critical listening time to help us

to go back to the drawing board.
Thanks to each of you for applying your consummate skills to this project.
Your faith, encouragement, enthusiasm and patience helped us get it right.

Introduction
Thank you for your purchase oftheMPXG2 Guitar Effects Processor. TheMPX
G2 works with any amp, from combo to stack, allowing you to place authentic
effects anywhere in the signal chain without altering the amps basic tone. Two
separate signal paths allow you to place effects where you want them. For
example compression, wah and analog overdrive can be placed in front of the
amp, while other effects, like delay chorus and reverb might be placed in the
amps effect loop.
Effect buttons light to show you
which are active in any program.
Push any lighted effect button to
instantly bypass the effect. Press it
again to turn the effect back on.
Dynamic Gain™, Lexicon’s new analog distortion technology provides scream-
ing overdrive and warm distortion tones which can be used as an analog stomp
box in front of your amp or as a stand alone preamp for direct recording or live
performance.
Database Sorting Options
Seven primary effect types: Gain, Effect 1, Effect 2, Chorus, Delay, EQ and,
Reverb give you push button access to 76 effects, including extraordinary
recreations of classics like the Uni-Vibe®, Dyna-Comp®, Phase 90®, Vox® and
Cry Baby® wah, intelligent pitch shift, a JamMan™ style looper with 20-second
full bandwidth delays, Chorus, Flanger, Sweepfilter, Detuner, Rotary Speaker,
Parametric EQ and Tremolo.

Installation Notes
The MPX G2 uses one EIA-standard rack space, and can be mounted on any
level surface or in a standard 19 inch (483 mm) rack. If the unit is mounted in a
rack or road case, support the rear of the chassis to prevent possible damage
from mechanical shock and vibration.
Mounting
The maximum ambient operating temperature is 104°F (40°C). Provide ade-
quate ventilation if the unit is mounted in a closed rack with heat-producing
equipment such as power amplifiers.
Power Requirements
The MPX G2 is equipped with a 3-pin IEC power connector and detachable
cord. The unit will operate with power sources from 100 to 240 volts AC, 50-
60Hz. Power switching to actual line voltage is automatic.

Following are diagrams showing signal flow in the MPX G2 Pre-Gain and Post-
Gain paths. When combined, these two diagrams show the entire signal path
between your guitar and the Main Outputs when the MPX G2 is used as a
standalone processor. Depending on which effects are active in a given
program (and where they are placed), the MPX G2 will automatically route
around unnecessary analog circuits as well as A/D and D/A converters. This
allows signal-to-noise and dynamic range to be optimized for every program.
Signal Flow
Effect 1, Effect 2, Chorus, Delay, Reverb and EQ can be placed in any
combination on either, or both, pre gain and post gain paths.

This is the effects loop processing path when the Insert Returns are connected
to your amp’s effects loop sends (post gain path). The built-in Insert Router and
Digital Router automatically configure the signal flow based on which connec-
tions and settings you’re using. The stereo noise gate can reduce stage levels
to near silence when you stop playing - without muting the tails of post gain
effects like delays or reverbs.

The MPX G2 is a complete guitar processing system. As such it has two
independent audio paths: one for effects that go directly between the guitar and
the input to the amp (pre-gain path), the other for effects that are inserted in the
amp’s effects loop (post-gain path). Analog Dynamic Gain effects (Tone,
Crunch, Screamer, Distortion, and Preamp) are dedicated to the pre-gain path.
The other 70 effects can be placed anywhere on either path and each one of
the 300 MPX G2 programs can have its own unique combination of effects,
distributed on either path.
Dual Audio Paths
Whendifferent pieces ofaudiogear are connectedtogether, care mustbetaken
toavoid groundloops (whichcancause noise and hum problems). TheMPXG2
uses a special grounding scheme to safely minimize grounding-related prob-
lems. All circuits are internally connectedtoacommongroundplane. (This isthe
same approach used to ground racks of gear in studio installations and touring
rigs.) The chassis is isolated from the printed circuit board to prevent ground
loops through the ground pin of the AC cord. No special cables are required
when connecting the MPX G2 to other equipment.
Internal Grounding
Note that the G2 must always be properly grounded via the ground pin in its AC
line cord.
With the exception of the Main Outputs and the stereo Headphone connectors,
all ofthe1/4" connectors are unbalancedmonojacks. For best performance use
high-quality, shielded instrument cables.
Unbalanced
Connections
The MPX G2 has two high impedance guitar inputs: one on the front panel and
another on the rear panel. Connecting to the front panel input will override a
connection made at the rear panel input.
Guitar Input
For best performance, maintain balanced connections, and use high-quality,
low-capacitance, shielded twisted-pair cable. Use shielded instrument cables
for unbalanced connections.
Main Outputs
When connecting the MPX G2 XLR outputs to single-ended, unbalanced
devices, leave the low side floating and connect the grounds between the
units.

TheMPX G2Insert Sendis alwaysactive. WhenGain is on, its signal is from the
Gain block output. When Gain is bypassed, or when no Gain effect is in the
program, its signal is from the Gain block input. Note that this signal passes
throughaprogrammablelevelcontrol(Edit mode:Mix:SendLevel)andanalog
noise gate before leaving the unit via the Insert Send jack. Note also that
whenever there are no active effects between the guitar input and the Insert
Send, a relay automatically switches in a “straight-wire” bypass path. This
ensures that there is nothing between your guitar and your amp unless one or
morepre-gaineffectsareactive.(UntiltheMPXG2,theonlyway togetthissame
kind of analog purity when using effects was to install a dedicated effects loop
switching unit.)
Insert Send
Inserting a jack into either (or both) Insert Return connectors breaks the
normalled connections between pre-gain and post-gain paths, allowing you to
insert an external device (guitar preamp, effects processor, etc.) into the MPX
G2signal path. Whenanexternal device is inserted, thefront panel Insert button
LED will light.
Insert Returns
The external device can be bypassed by pressing Insert (its LED will go out).
When the MPX G2 is connected to an amp’s effects loop, you can usethe Insert
button to bypass the amp’s preamp and send MPX G2 signals directly into the
amp’s power amp. This feature allows you, for example, to switch between your
amp’s high-gain channel and an MPX G2 Gain effect clean channel.
TheInsertReturnjackshavesoftware-controlledsensingandswitchingcircuitry
to automatically route signals depending on which jacks are used and the MPX

Automatic
Insert Return
Signal Routing
When only the Right Insert Return is connected, its signal is split and sent into
boththeleft andrightchannels ofthepost-gain path. Whentheunit is bypassed,
the dry Insert signal will be present at both outputs.
Right (Mono) Only
When both Left and Right Insert Returns are connected, their signals are sent
in stereo to the left and right channels of the post-gain path. When the unit is
bypassed, the dry stereo signal is present at the outputs.
Stereo
When only the Left Insert Return is connected, its signal is sent only to the left
channel of the post-gain path. The right channel of the post gain path is
“normalled” to the right channel of the pre gain path. When the unit is bypassed,
the dry Insert signal is present on the left output and the Guitar Input signal is
present on the right output.

When the MPX G2 leaves the factory, Insert connections are routed in series
between the pre-gain and post-gain paths. (This is the best routing to use when
connecting to amplifier effects loops.) You can alter this routing by changing the
setting of the Insert parameter in the System: Modes menu. Be sure to read
about the three different Insert Modes (FX Loop, Mix and Parallel) in Chapter 5:

between dramatically different tones with a single button push.
The MPX G2 has three dedicated front panel tone controls which allow instant
modification of the Low, Mid and High settings of the Dynamic Gain effect in the
current program. These controls are analog pots. Changes made with these
knobs take place immediately (You don’t have to pass-through the current
value- once you move the knob, it “owns” the parameter.)

Programmable
Bypass Modes
As the MPX G2 is designed with separate pre-gain and post-gain effects paths,
the master Bypass button can be progammed to function in a variety of useful
ways. The factory setting is for both paths to be bypassed when Bypass is
activated. You can choose, however, to have this button bypass only the pre-
gain path, only the post-gain path or both paths.
Bypass behavior for each path can be independently programmed as well. The
pre-gain path can be set to Disabled or to provide an analog "straight wire"
Bypass.
The post-gain path can be set to Input Mute (delays and reverbs will "ring out"
when bypassed), All Mute (no output when bypassed) or Bypass. When set to
Bypass, the post-gain path has an optional Bypass Level parameter that
allows you to set an independent level for when the post-gain path is bypassed.
You can choose to have Bypass
bypassthepre-gainpath,thepost-
gain path, or both paths in System
mode.
(Be sure to read about SendBypass and PostBypass under System: Modes in
Chapter 5: System Controls.)

The main purpose of this control is to allow you to match the overall Pre-Gain
effects level with the level when the Pre-Gain path is bypassed. It can also be
used to provide clean boost to add additional punch to kick a clean amp into
overdrive.
Send Options: Send Byp Level
This parameter controls the Send output level during the transition between two

ThePost-Gainpathalsohas programmable effects andbypasslevels. ThePost
Level parameter sets the overall level of wet (effects only) signal. It can add as
much as 6dB of additional gain.
Post Options: Post Byp Level
This parameter sets the output level of the Post Gain path when it is bypassed.
A setting of 0dB corresponds to unity gain.
These parameters allow you to match Post-Gain effects and bypass levels so

The MPX G2 has a progammable analog speaker simulator which is located
between the pre- and post-gain paths. When used as a stand alone processor,
the speaker simulator is connected to the output of theMPX G2 analog preamp.
Speaker Sim
The speaker simulator can be set to Global or Program mode. When set to
Global, the current speaker simulator settings will be active for all programs
when they load. (This is a quick way to turn the speaker sim on or off for all
programs.) When set to Program, each program will load with its own Speaker
Sim settings.
When the speaker simulator is active, a small speaker icon appears in the
Program display.
Be aware that the factory programs that use the speaker simulator were
designed to sound best when the MPX G2 is used as a stand alone processor.
These will sound overly dark if used through a guitar amp and speaker cabinet.
(Just turn Speaker Sim off if you want listen to them through a guitar amp.)
NOTE: You can use the simulator
to processthe output of an external
preamp by simply connecting the
external preamp to the MPX G2
Return jack(s). The speaker simu-
lator is a mono circuit. When both
returnsareused, theyare summed
to mono within the speaker simula-
tor.
Likewise, factory programs that don’t use the speaker simulator will sound best
throughaguitar amp. Programs that use again effect anddon’t usethespeaker
simulator will sound harsh when you listento them directly through headphones
or at a console. (Turn Speaker Sim on to listen to these programs direct.)
There are 4 cabinet designs to choose from: Combo1, Combo2, Stack 1 and
Stack 2.
See diagrams on the following
page.
Combo 1 is an open-back cabinet with 10” speakers.
Combo 2 is an open back cabinet with 12” speakers.
Stack 1 is closed back with 12” speakers.
Stack 2 is closed back with 10” speakers.
Each cabinet can loaded with one of four speaker types: Bright, Normal, Warm,

The MPX G2 has two integrated noise gates, one analog and one digital. Both
are drivenbythedirectsignal. Thegatesshareacommonsetofparameters and
can be used independently, or combined to create a “super gate”.
Noise Gate
The analog gate is the final output stage of the MPX G2 pre-gain Insert Send
path.Thisallowsyoutogatetheanalogsignalconnectedtoyourguitaramp.The
attack and release times of the analog gate are fixed (both are preset to be very
fast).
The digital gate is located on the post-gain path, immediately after the Insert
Returns. This stereogateallows youtogatetheeffects Sendsignal comingfrom
an external guitar preamp before it is processed by any post-gain effects such
as reverb or delay. (This means that reverb and decay tails will ring out naturally
when the gate shuts down.) The digital gate is driven by the same pure guitar
signal as the analog gate, so both gates have the same sensitivity to light touch
— no matter how many effects the guitar is going through.
Given a choice, many players
prefer not use gates of any kind
as they can affect tone and play-
ing style dynamics. In live and
recording situations where high-
powered amps are pushed hard,
however, the use of a gate is
sometimes unavoidable. (If a
player uses stomp-box effects in
front of the amp, and rack effects
in the effects loop, two gates are
required: one between the amp
input and the last stomp box in
the effect chain, and another on
the amp's effects send to gate
noise before it hits the rack pro-
cessors.)
When the MPX G2 is connected in front of an amp and/or in the effects loop,
these two gates form an integrated noise reduction system that provides more
than120dB ofattenuation. WhentheG2 is used withamp input only, theanalog
gate provides 40dB of attenuation. When the MPX G2 is used as a stand alone
processor, the digital gate provides 90dB of attenuation.
Signal Flow with no Returns connected
In a component system, the gate
is driven by the processed guitar
audio — which means that the
threshold must be set quite high
to compensate forall of the noise
added by the pre-gain effects
(wah, compressor, overdrive,
etc.).Youhavetoplayprettyhard
to get the gate to open up, and
sustained notes are noticably
chopped off.
nals
d to
taudio frthe rpath (no In-
sertsconnected)ortogateaudio comingin
through the return jacks.
As the MPX G2’s analog gate is
driven by the unprocessed gui-
tar, the threshold can be set
much lower, creating a sensitive
gate that opens up with a very
light touch and which remains
open considerably longer during
sustaining notes and chords. It
also makes it possible to use the
guitar’s volume control to con-
trol the gate directly.
Signal Flow with Returns connected
Both the analog and digitalnoise gates
share the same sensing — which can
be set to either Guitar Input or Return
Only.

The MPX G2 allows you to reconfigure the effect blocks along audio paths of
your own design. The Routing Map is a graphic display that shows routing and
connectionsbetweentheMPXG2effect blocks.Use theRoutingMaptochange
connections between individual effects and also to change the overall routing
configuration of all seven effect blocks as a group. All of the routing controls
available in the Routing Map menu are explained in this section, along with
examples of the selections you can make. Remember that you can change the
order of the effect blocks as well. (See Effect Ordering on the previous page.)
In these examples, we'll use the default effect order to keep things simple.
Routing Map
Before going into the details of the Routing Map, it's worthwhile to review basic
signal flow through the MPX G2.
The overall signal flow through the MPX G2 is divided into two paths: a pre-gain
path and a post-gain path. The six DSP effect blocks (Effect 1, Effect 2, Chorus,
Delay, Reverb and EQ) can be placed in any combination on either the pre-gain
or post-gain portions of the audio path.
The position of the Gain effect block in the Routing Map determines the
boundarybetweenthetwopaths.Thepre-gainpathismadeupoftheGaineffect

post-gain path consists of all effects on the path connected to the outputs of the
Gain effect block.
When you want to connect the G2 to external guitar amp or other gear, it is
important to understand where the SendandInsert Returns are in relationtothe
Routing Map display. The Send jack is permanently connected to the path at a
point immediately following the Gain block outputs. The Insert Return jacks are
permanently connected to the path at a point immediately following the Send.

The path through an MPX G2 DSP effect block looks like this:
Note that the dry path through the effect is stereo, and a variable wet/dry mix is
included for each DSP effect. The wet path through the effect can be stereo or

creative applications of the routing and connection capabilities of the MPX G2.
Example 1:
Program 198 Cordovox
Cordovox Routing Map
(Stand Alone)
This program produces the sound of a vintage Cordovox rotary speaker. The
Cordovox is a speaker cabinet containing a fixed 8-inch speaker mounted
behind a rotating baffle. It projects sound out of the sides and top of the cabinet,
not the front. The baffle can rotate at either fast or slow speeds. The transition
time between the different rates is quite long. The characteristic swirling sound
it producesis theresult ofdoppler andpanningeffects combinedwiththelimited
bandwidth of the small, easy-to-distort speaker and the tone qualities of the
amplifier used to drive the Cordovox cabinet.
In this program, the guitar is first routed through the Gain block, which uses the
Preamptomimictheampandspeakercharacteristics.TheoutputofthePreamp
is connected to the Chorus block. The Stereo Chorus produces the doppler
portionsoftheoverall sound. TheChorus blockoptionis settoSplit, creatingtwo
parallel audio paths. Effect 1 and Effect 2 are placed on these lower and upper
paths, and each is loaded with an Auto Panner effect.
Effect 2 is connected to the left output of the Chorus block and Effect 1 is
connected to the right output. Each Auto Panner “sees” a different input signal
and, together they produce the complex panning dynamics required to simulate
the complex stereo image created by miking the cabinet with left and right
microphones.ThestereooutputofEffect2isconnectedtotheReverbblock.The
Reverb outputs are summed with the outputs of the Auto Panner in Effect 1 and
sent to the Main Outputs.
The A/B controller is patched to the Chorus and Auto Panner rates to allow you
to choose between slow and fast speeds.

classic Octave Fuzz effects can be produced.
The Input block option is set to Split, to create two parallel paths. The paths are

Program 219 Infinite Echo
(Stand Alone)
Infinite Echo Routing Map
The Infinite Echo program is an analog tape delay effect with auto ducking and
infinite feedback. It demonstrates the routing techniques used to create an
analog feedback path. This unique feature of the MPX G2 makes it possible to
recreate the sound of classic analog delay, chorus and flanger effects.
The guitar signal is routed through the Delay block, which is loaded with
Echo(M). The Delay block output is connected to the Gain block. Here the
Overdrive effect is used to impart the tone and distortion characteristics of the
preamp in avintageanalog echoeffect. TheGainblock optionis set toSplit. The
upper path is used as the “normal” path to the Main Outputs. The Reverb block
is placed on this upper path to add some Hall reverb to the overall sound.
The lower path is used as a feedback path to the Delay block. It consists of a
detuner,compressorandvolume control,inseries.Thefeedbackpathiscreated
by setting the Delay effect Fbk Insert parameter to Effect 2. (Be sure to read
about this option of the Fbk parameter in the Delay Effects portion of Chapter
7:TheEffects andParameters.) Thiscreatesafeedbackpaththat flowsfrom the
ouput of Effect 2 back into the Echo(M) effect. The master level of the signal is
controlled by the Echo(M) Fbk parameter. All of the blocks between the Delay
and Effect 2 blocks are also in the feedback path. Every time the Echo repeats,
thesignal recirculates through the analogGain block aswell as theDetuner and
Compressor.
The volume control is set to Off, so no audio from this path is passed to the Main
Outputs. Also, the program is stored with the Insert bypassed to keep the guitar
amp preamp out of the feedback loop in Amp Input and FX Loop applications.
These tricks allows the program to be used whether connected for Stand Alone,
Amp Input Only or Amp Input & FX Loop applications.

The Overdrive effect produces the analog tone and saturation of tape echo
electronics.The Detuner is patched to the Random controller to add pitch
fluctuations caused by the wow and flutter typical of tape delay mechanical
systems. The Compressor limits the feedback signal so that it never goes
completely out of control. As new notes are played, the compressor lowers the
feedback level. When the playing stops, the echo repeats begin to swell in
volume, but the compressor keeps the swell from going into overload. This
allows feedbacksettingstoproduceinfinite repeat — withthe soundevolvingon
each repeat. A/B is patched to clear the delay.

to take is to think about what you want before changing anything.
Notes and Tips on Routing
2. When changing the routing options, work from left to right — from the input
block to the output block.
3. The MPX G2 will only display the routing options that are available in the
currentconfiguration.Forexample,ifallsevenblocksareontheupperpath,
the only available option will be Split. The next block downstream from a
Split will have Upper, Lower, and Merge available as options.
4. The MPX G2 automatically updates the routing options downstream from
the selected block as necessary. For example, if you change a Split path
to Upper, all of the following blocks will be set to Upper as well.
5. You can also move effects while the Routing Map is displayed:

The parameters in the Tempo menu: Rate, Source, Beat Value, Tap Average,
Tap Source and Source Level, allow you to select the way in which the actual
tempo in BPM is determined for each effect.
Tempo
The MPX G2 gives you unique control over tempo. In the MPX G2, any delay
parameter and any time-based modulator (LFO, etc.) can be individually
assigned to an absolute time value, or assigned to a tempo value.
For example, a delay time can be set to a specific number of milliseconds, and
you will always get a delay of that number of milliseconds, regardless of tempo
changes. Alternatively, a delay time can be set to a specific ratio of echoes to
beats. Now, if you create a rhythmic echo pattern, delay times will be linked to
tempo.Whenyouchangetempo,thedelay timewillchangetomaintain thesame
rhythm at the new tempo.
With the LFOs, the rate of change can be an absolute value (such as once per
second), or it can be linked to tempo (for example, once every four beats). Any
delay parameter or LFO rate canbesettoits ownindividual rhythm, allowing you
to set upan effect which will change in arhythmically interesting way — evolving
over time, for example, as opposed to being a mere series of repetitions. Once
delaysandLFOratesareassigned,temporatecanbeeasily changedinavariety
of useful ways.
Tempo Rate can be set internally or via MIDI Clock. If Tempo Source is set to
Internal, you can dial in any tempo from 41-400 BPM, or you can press the front
panel Tap button twice in rhythm to establish the rate you want (allowing you to
change tempo on the fly from any mode). You can also have thevalue of a patch
source act as a tap trigger (See Chapter 4: Patching.) or choose to have your
tempotransmittedasaMIDI Clock signal tocontrol thetempo ofconnectedMIDI
devices. (See Chapter 5: System Controls or Chapter 6: MIDI Operation.) If
Source is set to MIDI Clock, MPX G2 tempo will sync to incoming MIDI Clock.
Whether tempo is set internally or via MIDI, the front panelTempo LED will flash
at the current rate whenever any delay or LFO rate is set for tempo control.
MPX G2 programs can have their own tempo rate settings which are stored with
the program. You can override these individual tempo rates with a global tempo
rateintheSystem Setupmenu. Tempois alsoavailableasanindependentpatch

Patching is the ability to assign a control (Source) to a parameter (Destination).
This allows you to alter the value of the parameter by manipulating the control
Source. For example, you can select the front panel knob as a Source and an
effect's Mix parameter as a Destination. This simple patch will allow you to
dynamically alter the mix of the effect whenever you turn the knob.
Patching
You can create as many as five patches. You can patch multiple parameters to
a single controller, or patch multiple Sources to a single Destination. This
chapter contains all the information you need to use the MPX G2 program
patching system. Global Patching is described in Chapter 5: System Controls.
MPX G2 Patch controls are accessed in Edit mode.
In the Edit menu, select Patching to access the patch assigned
to a displayed parameter, or to create or alter a patch.
When a Patch is selected, the display will show:
Use the knob to select a Patch
number (1-5).
Patch select:

The numeric display will show the Patch
number you have selected.
The Patch number you select in the alphanumeric display will be displayed on
the large numeric display as well. This display will remain on as long as you are
in the Patching System to identify the currently selected patch.

Selecting a Source
and Destination
Patch Sources
All Sources are the same in the
sense that each generates an out-
put value in the range of 0-127. The
output value is used to increase or
decrease the setting of a Destina-
tion parameter value. Some gener-
ate values continuously (they're al-
ways "on" ); some generate output
based on the position of a particular
external MIDI controller, or a
footpedal, or footswitch. Some
Sources generate output based on
aspects of physical performance
such as how loud, how fast, or how
hard you play. The MPX G2 allows
you to choose a Source for each
Destination from the following list.
In this example, the Source assignment
field is selected. The knob willscrollthrough

For example, if a Footpedal, andtheknobare both assignedtoMstr Mix, theMix
value will be the sum of the patch Destination values for those two patches.
When creating multiple patches to the same Destination, you should set the
individual Destinations to values which, when added together, are less than or
equal to the maximum value for each parameter. The Footpedal and the knob,
for example, could each have a maximum value of 50%, or they could be
assigned values of 25% and 75%, 60% and 40%, etc.
When the sum of multiple patched parameter Destination values is greater than
the maximum value of the parameter, the parameter value will remain at
maximum until the sum of the patches falls below it.

Selecting Manual allows you to scroll through programs in Program mode,
viewing them according to the DataBase criteria you've selected. Programs
which are not loaded are identified by an asterisk (✱) preceding the displayed
name, and flashing of the Program button LED. Press Program to load the
displayed program.
Selecting Auto (the default setting) will cause programs to be loaded automati-
cally following a brief timeout whenever they are selected in Program mode.
Each MPX G2 program has its own Post Mix and Level parameters, as well as
individual mix and level settings for each Effect. These settings are stored as
integral parts of the program. The Mix parameter allows you to select Program,
to have each program load with its own Mix setting, or Global which allows any
program Mix setting to become the global setting for all subsequently loaded
programs.
Mix
Pgm Bypass allows you to determine the behavior of the MPX G2 during the
transition when a new program is loaded. The choices available are: All Mute
or Bypass.

Tempo Mode
The MPX G2 gives you an exciting approach to working with delay times and
modulation parameters. You can set these parameters in beats, allowing you to
control your programs in a completely musical way. Each MPX G2 program has
its own Tempo parameters, with tempo settings stored as an integral part of the
program. These include Tempo Rate, Tempo Source (Internal or MIDI), Beat
ValueandTapSource. The Globalsettinghereallows youtooverrideindividual
Tempo Rate settings with a global value which can then be changed on the fly.
When shipped, the MPX G2 has the Tempo Mode set to Program, with each
program driven by its own stored tempo rate. To change to a global tempo rate,
select Global here.
Whether Tempo Mode is set to Global or Program, you can set a new tempo
rate by pressing the front panel Tap button twice. Alternatively, you can choose
to have tempo set automatically from incoming MIDI clock. The rate you tap, or
the MIDI tempo, will become the global setting.

Send Bypass
The SendBypass parameter allows you to set the bypass behavior of the pre-
gain path (everything between the Guitar Input and the Insert Send jack) when
the front panel Bypass button is pressed. The choices are:
Disabled: Bypass has no effect on the pre-gain path.
Bypass: An internal relay bypasses the pre-gain path with an analog
"straight wire" between the Guitar Input and the Send jack. (This
is the default setting.)
Insert Mute: Bypassbypasses thepre-gain pathwith ananalog "straight wire"
between the Guitar Input and the Send jack.
Insert Mute mutes thepre-gain pathafter theSendand bypasses
the Insert Return jacks. This allows the Insert button to be used
as a preamp bypass when the MPX G2 is connected to a guitar
amp input and its effects loop.
Insert
Formaximum flexibility whenconnectingothergear totheG2via theInsertSend
and Return jacks, three Insert Modes are provided: FX Loop, Mix and Parallel.
FX Loop allows gear to be connected in series between the pre-gain and post-
gain paths. This is themost useful setting whentheMPX G2is used withaguitar
amp that has an effects loop, when an external processor is connected to the
MPXG2, or whenthe MPXG2is usedas astandalonepreampwitheffects. This
is the default setting.
In this mode, signals inserted into the MPX G2 rear panel Return jack(s) are
passed through a level control, a selectable analog speaker simulator, and then
routed (via 24-bit A/D converters) into the post-gain DSP path. In the MPX G2
Effect Order or Routing Map display (Edit mode), the return signal is inserted
immediately after the Gain block (G in the display).
Mix mode allows the return jacks tobe used as an analog line mixer. This mode
is provided for applications when you want to have additional, unprocessed
audio mixed with the outputs of the MPX G2. For example, you would use this
mode to Insert the output of a CD or DAT player so you can play along with
headphones. Signals inserted into the MPX G2 rear panel Return jack(s) pass
through the level control and are mixed with the main and headphone outputs
ofthe MPXG2. Note that whenthis modeis selected, theReturnsignals are not
processed by the MPX G2.
Parallelmodeallowsgeartobeconnectedinparallelbetweenthepre-andpost-
gain paths. Use this mode if you want to convert a serial guitar amp effects loop
into a parallel loop. The parallel signal path provided by this mode allows thedry
analog guitar signal to pass directly to the power amp without running through
any converters. Note that when using a parallel effects loop, the Post: Mix

Three controls are available here for customizing the MPX G2 Tuner settings:
Cal, Offset and Bypass.
Tuner Mode
Cal Use this parameter to set the Tuner's "A" pitch. The factory setting is
A=A. If youchangethis, for example, toA=G, youcantuneyour guitar
down a whole step — but the open strings will still be displayed as E
A D G B and E.
Note: If you change this setting, this will also be used for reference in
the Diatonic Hmy effect.
Offset You can fine tune the Tuner's "A" pitch over a range of ±50 cents to
match a recording or a non-A440 tuning reference.
Bypass The factory settingof this parameter isMute which turns offthe Send
andMainOutputswhileyou'retuning.Post Mutemutes only theMain
Outputs— dry guitar is sent out theSendwhiletheTuner is active. All
Bypass sends dry guitar out both the Send and Main Outputs while
the Tuner is active.
TheGlobal Effects modesprovidequick anduseful ways ofchangingtheoverall
behavior of the G2 to fit specific applications. They allow you to choose to make
the Speaker Simulator, Noise Gate, Reverb, and Master bypass functions
universal or program specific.
Global Effects
In each case, setting the mode to Global lets the current settings override the
individual settings stored with each program — a very handy feature if you want

Speaker Sim Mode
When Speaker Sim mode is set to Global, the current settings of the speaker
simulator override the settings stored with each program.
If you’re connected to a guitar amp and playing through guitar speakers - you’ll
want the Speaker Sim turned off in all programs.
If you’re playing or recording directly into a mixer, you’ll want the Speaker Sim
turned on (at least for any programs that use Gain Effects).
When Speaker Sim mode is Global, its settings are not saved with a program
when it is stored. To save the settings with a program, the mode must be set to
Program.
Noise Gate Mode
SettingNoiseGatemodetoGlobalappliesthecurrentsettingsoftheNoiseGate
to all programs in the MPX G2. In this mode, you can edit the Noise Gate
parameters as usual. Note, however, that to save the settings with a program,
the mode must be set to Program.
Reverb Mode
When Reverb mode is set to Global, the reverb settings in the current program
overridetheindividualreverbsettingsstoredwitheachprogram. Thisallowsyou
to keep the same reverb while you load different programs. (So, for example,
when you get the perfect reverb settings with your amp in a particular club - you
don’t have to edit and store the reverb for every program you plan to use that
night.)
With Reverb mode set to Global, you can edit reverb parameters as usual —
even change algorithms. Note, however, that your reverb settings will not be
saved when you store the program. To save reverb settings with aprogram, the
Reverb mode must be set to Program.
With Reverb mode set to Global, the reverb bypass state also becomes global.
If you bypass the reverb, it will stay bypassed — even when you load new
programs — until you make it active again.
Bypass Mode
When Bypass mode is set to Global, the current Master bypass state is not
changed when a new program is loaded. Once bypassed, the MPX G2 will stay
bypassed until you press Bypass again (even when you load new programs).
In this mode, the bypass state is not saved with a program when it is stored. To
save the state with a program, this mode must be set to Program.
When Bypass mode is set to Program, the Master bypass state stored with a
program becomes active when the program is loaded. (Just like the individual
effects bypass states, the Master bypass state can be stored with a program.)

MIDI Operation
Most MPX G2 parameters and all programs can be accessed by MIDI. All MIDI
applications require theMPXG2to beconnected withoneor more MIDI devices
with standard MIDI cables via the rear panel MIDI jacks.
Selecting a
MIDI Channel
MIDI controls, such as Transmit and Receive Channel selection are available in
the System mode MIDI menu. All of these controls are described in Chapter 5:
System Controls. Several are repeated here for your convenience.
Before using the MPX G2 with other MIDI devices, all devices must be set to the
same MIDI channel. To set the MPX G2 to receive MIDI:
1.
2.
3.

JamMan NOTE
When the JamMan effect is loaded
(Delay block) and the MIDI Clock

the loop definition. A MIDI Stop
message is sent when the loop is
reset or the MuteS(Start/Stop) pa-
rameter is used. (MIDI Stop on
mute and MIDI Start on de-mute.)
Sending a MIDI Program Change message from the controller will load an MPX
G2register. If any MIDI sourcesareactiveasglobal or general purposepatches,
moving the appropriate control on the controller will cause the patched destina-

Some synthesizers and controllers cannot send the full range of MIDI program
change messages (1-128). Others may appear to be able to send only 32, but
actually have a bank mode that does let you send all 128 program change
messages. Also, be aware that some MIDI devices use a program numbering
system that uses 0-127 instead of 1-128. If in doubt, see the manual for your
controller. See also MIDI Pgm Offset on the following page.

in which the MPX G2 interprets these messages is determined by the value of
this parameter as follows:

Pgm Change: Off
All Program Change and Bank select messages are ignored. Pgm+ and Pgm–
controllers will load the next higher or lower program in the current bank.
Pgm Change : On
Program Change messages 0-99 are recognized. Program Change messages
100—127 are ignored except when MIDI maps or chains are active.
Pressing Options from the Pgm Change display allows you to select a Pgm#

Automation
SysEx Automation
TheMPXG2will transmit SysEx automationmessages whentheSystem mode
MIDI Automation parameter is set to On. Virtually all changes made by front
panel operations are transmitted asMPXG2 SysEx messages. This is intended
primarily for use by editor programs and in configurations where it is desirable
for one or more MPX G2s to be slaved to a single MPX G2 acting as a master.
The current mode (Program, Edit or System) of the slave does not follow the
master, but the actual parameter values do. (SysEx automation can also be
stored on a sequencer and replayed in real-time. As a general rule, automating
more thantwo or threeSysEx parameter changesatonceis not recommended.)
To set up the MPX G2 to receive SysEx automation messages from another
MPX G2, or from a computer editor/sequencer, the transmitting and receiving
MPX G2s should be set up as follows:
Transmitting MPX G2: System mode MIDI Automation set to On
(Default=Off)
Recieving MPX G2:
System mode MIDI SysEx Receive set to On
(Default=On)
The Receive Device ID of the receiving MPXG2, and theXmit Device ID of the
transmitting MPX G2 must match. The Receive Device ID is an Option of the
MIDI SysEx Receive parameter. The Xmit Device ID is an Option of the MIDI
Automation parameter.
For applications where it is desirable to "automate" changes made to MPX G2
effects with its own controls ( the Knob, Footpedal or Footswitch), we recom-
mend assigning the controllers to MIDI destinations (see Chapter 5: System
Controls MIDI Send) and recording the MPX G2 MIDI output with a MIDI
sequencer.
Controller Automation
Reset All Controllers
The MPX G2 recognizes the “Reset All Controllers” message. When received,
all patched parameters are reset to their stored values, or to the last front panel-
edited values. Patched parameters may also be reset from the MPX G2 front
panel —in System mode select Ctl Send from the MIDI menu and press
Options. (The message will be transmitted from the MPX G2 as well).
MIDI Clock and The MPX G2 recognizes incoming MIDI clock messages when the Edit mode
Tempo Source parameter is set to MIDI. Any Delay parameter set to
echoes:beat, or any LFO parameter set to cycles:beat, will be synchronized to
the tempo of the incoming MIDI clock.
Clock Commands
JamMan NOTE
When the JamMan effect is loaded
(Delay block) the loop size will be
determined by the Beat Value
(number of beats) and the tempo of
the incoming MIDI Clock. Like the
original JamMan device, only one
Tap is required.
MIDI Clock and Clock Commands (Start, Stop, Continue) are also available as
Dynamic MIDI patch sources. The value of MIDI Clock when used as a patch

Different effects requiredifferent amounts ofMPXG2processing. Thefollowing
notes should be kept in mind when creating new combinations of effects in a
program.
Notes on
Combining Effects
All Reverb and Gain effects have dedicated processing and can be used in
combination with any other effect. (You can always add these to any MPX G2
program.) In addition, the Noise Gate and Speaker Simulator don’t share
resources with the effects and are, therefore, always available.
The other effects (Effect1, Effect2, Chorus, Delay and EQ) share processing
"steps". The total number of available steps is 190. This means that some
combinations of these effects may not be possible –depending on which effects
are already loaded.
When you scroll through the effects for a given block, the size (in steps) of each
effect is shown in the upper right hand corner of the display. If the effect will fit
in the current progam, anasterisk (*) is displayed next toits name andthe Effect
button will flash rapidly. If the effect will not fit, an “x” is displayed, and the Effect
button light will turn off.
Whenyoustopscrolling,aresourceusagemessageisdisplayedbrieflyshowing
how many steps are available and how many steps have been used.
Notes on
Controlling Effect
Parameters
AnyeffectparameterintheMPXG2canbepatchedforrealtimecontrol.Insome
cases, audible artifacts may be produced, depending on the particular param-
eter and the rate and range of control. In many effects, we’ve added additional
processingpowertoparametersthatare obviouscandidatesfordrasticdynamic
control. These parameters are “interpolated” to produce extremely smooth,
noise free control.
It is often possible to compensate for a non-interpolated parameter, such as
Effect 1 Detune Level, by combining the effect block with one with an interpo-
lated Level parameter, such as Effect 2 Volume.
In the following effect descriptions, a bar showing the processing requirements,
in steps, of each effect in relation to the total possible number of steps (190) is
shown at the end of each description.

Unlike the other MPX G2 Gain effects, Preamp was not designed to function as
a stomp box to use in front of your amplifier. It is a fully featured, programmable
analog guitar preamp. Use Preamp for stand-alone applications (direct record-
ing without an amp, or to drive a power amp and cabs). When using Preamp for
direct recording, be sure to turn on the Speaker Simulator (Edit Select, Speaker
Sim, Simulator: On).
InLvl (Input Level) determines the amount of clean headroom the preamp has.
The setting of this single control will have a great impact on the overall behavior
and sound of the preamp. At higher values, the preamp will distort very easily
—forexample, withaMidtonecontrolboostofonly5dB.Atlowerlevels,thetone
controls behave more like EQ controls — making low, mid and high guitar
frequencies louder (or softer) without adding distortion.

The Effe c ts a nd Pa ra m e te rs
As a general guideline, set InLvl to approximately -15dB when working on clean
or crunch sounds. Use higher values when you’re going for more over-the-top
distortion.
As with any preamp, a little
time taken to learn how the
controls interact with one an-
other will pay off when you’re
searching for "the sound".
Be aware that this preamp can produce well over 120dB of analog gain.
Dependingonthesettings of InLvl and Drive, the threetonecontrols will behave
like EQs or distortion controls. Unlike many preamps, these controls are active
— meaning that they can boost the signal (add gain) as well as cut it. Each
control can add up to 25dB of gain boost. Pay attention to the total amount of
boost — in most cases, a little goes a long way.
Oneofthefundamentaldis-
tinctions between different
types of preamps is how clean
or dirty it is. This distinction is
generally determined by the
preamp’s input sensitivity —
which roughly translates to
“How hard do I have to hit this
thing to make it break up?” In
most preamps this attribute is
fixed for each channel. (The
clean channel is less sensitive
than the lead channel.)
TheLoCut control is usedtoroll-offlow endbefore hittingthedrive sectionofthe
preamp. The higher the value, the fewer low frequencies in the distortion. This
control can be helpful in removing “mud” from high gain sounds, allowing them
to stand out in a mix.
The Feel parameter is a unique feature of Lexicon’s Dynamic Gain analog
alogrithms. In the Preamp effect, Feel is used to model the subtle changes in
distortion dynamics caused by different types of power-amp rectifier circuits.
When set to zero, the amount of compression/distortion produced during the
attack of notes is relatively constant. As this value is increased, you’ll notice a
differencein the feel of theattackof notesandchords when usingoverdriveand
moderate amounts of distortion. The first attack of a phrase of rapid picking is
a bit cleaner and has more bite than those that follow. This mimics the different
“power sag” envelopes that are characteristic of different power amp rectifier
circuits. A setting of 0 corresponds to the uniform response of a tight, solid state
rectifier cricuit. Values between 1 and 32 produce increasingly dynamic
responses- but are generally within therealm ofthoseproducedbypower amps
withsolid-staterectifiiers.Valuesabove32aremoreinkeepingwiththedynamic
feel produced by tube -rectified power amps.
The tone controls of a
preamp’s clean channel gen-
erally behave like EQ controls
on a mixer. They make
changes in what we hear as
bright, dark and warm without
adding distortion. It’s a differ-
ent story when you adjust the
tonecontrolsofmanypreamps’
lead channel. On these, the
tone controls interact with the
gain section and changing the
tone settings will often make
significant changes to the dis-
tortion characteristics of the
sound. In the lead channel of
many preamps, the Mid con-
trol can be used as a distortion
control. Turn it up to add more
distortion — down to make the
sound cleaner.
Drive sets the amount of overall gain in the preamp. The cleanest sounds are
produced with Drive set to 0. Distortion increases as the value of Drive is
increased.
Tone is a post-distortion high frequency rolloff control. Use it to control the high
frequency harmonics generated by the distortion. As Bass and Treble are also
post-distortion, they can further shape the sound by cutting or boosting top and
bottom without affecting the distortion.
The analog Preamp effect
in the MPX G2 has all of these
attributes. Because it is com-
pletely programmable, it is not
limited to clean or lead chan-
nelswithfixedinputsensitivity.
Careful adjustment of its pa-
rameters can yield many tonal
variations from clean and
slinky, to blues overdrive and
beyond, to a high gain roar.
Level is the master volume for the entire preamp. Use it to compensate for gain
cut or boost added by the combination of InLvl, the Tone controls and Drive.
When going for high gain sounds, lower the Level control to compensate for
increases in InLvl and Drive. A good way to set the Level control is to press the
Gain button to bypass the preamp so you can match the Preamp level with the
bypass level.
Split Preamp is the same analog effect as Preamp, except that it has a built-in
parallelpaththatfeedsthedirect,cleanguitartotheMPXG2’spost-gainsection.
This allows you to create programs that have preamp and right channel direct
guitar sounds simultaneously.

Effect descriptions for all of the effects contained in Effect1 and Effect2 are combined in
this section.
Effect1 and Effect2
Effect1 and Effect2 contain identical effects, except for the first seven effects in Effect1.
These are Pitch effects: Detune (M), (S)and (D), Shift(M), (S) and(D) and Diatonic Hmy.
In these effects, Tune controls the amount of pitch shift. The Optimize parameter (an
option of Tune) allows balancing of any artifacts vs. the amount of delay through the
effect. Higher settings of Optimize are good for chords and low notes, lower settings
minimize the delay through the effect.
Detune (M), Detune (S) and Detune (D)
Detune effects are useful for
Detune (M)
Detune (S)
thickening up sounds by adding
delayed/pitch shifted versions of
the original source. They can be
particularly effective when used to
simulate double-tracking. They
are also great alternatives to cho-
rus effects as a detuner can add
the richness of a chorus effect
without the audible sweep caused
by the chorus rate. Detuners are
also traditionally used to turn a six-
string guitar into a twelve-string, or
an in-tune piano into a honky-tonk.
The MPX G2 detuners are opti-
mizedtoprovideveryfineamounts
of pitch shift.
Detune (D)
Detune (M) is a single-channel
detuner that creates a pair of sig-
nals, pitch-shifted up and down
from the input. The pair is always
mixed together, and presented
equally to the outputs.
Detune (S) creates a pair of sig-
nals, pitch-shifted up and down
from the inputs. The left and right
channels are separate.
Detune (D) sums left and right
inputs to mono,then creates two
pairs of signals, pitch-shifted up
anddownfromtheinputsbyTune1
and Tune 2. The first pair goes out
the left, the second pair out the
right.

Shift (M) is a single-channel
pitch shifter.
Shift (S) is a stereo version of
Shift (M) with synchronized

essential effect for many guitar-

becomeadefiningelementofmany

Our version is modeled on a

DigiDrive1 and DigiDrive2
The DigiDrive 1 and 2 effects
combine digital distortion with 3-
band tone controls. In DigiDrive1,
the tone controls are in front of the
distortion. In DigiDrive 2, the tone
controls follow the distortion. The
distortion produced by these ef-
fects is not meant to mimic analog
distortion, but to provide an alter-
native sound. (Think “digital fuzz
box.”). The next time you’re look-
ing for an in-your-face fuzz effect,
pump one of these into your amp.
You might be surprised at what
comes out.

(CryBaby) or Model V (Vox).
These models capture both the
characteristic signature and non-

change the wah from a band-pass
type to a low-pass type effect by
progressively adding more low
end. (Try it with bass and key-
boards.) Resp controls how
quickly the wah responds to
changes of Sweep. (100 is very
fast, 0 is very, very slow).

Thechoruseffectsaregenerallyusedtoenhanceasoundbymodulatingdelaytimesand/
or frequency content in various ways. Of course, the classic effects of this type : Chorus,
Flanger and Phaser are all here – along with several other variations such as: Rotary
Cab, Aerosol, Orbits, Centrifuge, Comb 1 and Comb 2.
Chorus Effects
All of the Chorus effects have one or two resonance parameters. These parameters
control the level and phase of the effect output signal that is recirculated into the effect
inputs. Use care when adjusting these parameters, as they can cause overload (or
feedback-like howls) if they are set too high — even with little or no input signal present.
As a general rule, the combined value of any resonance parameters should always be
less than 100 — but pay close attention to levels whenever the total resonance is above
50. If you use high resonance values (to produce a deep flange effect, for example) and
the clip LEDs light, try turning down the level of the effect thatprecedes the Chorus block.
Chorus
This is a true stereo, multi-voice
chorus. Use it to enrich guitars,
keyboards, etc. It has Dual 2-tap
modulators with cross resonance.
The Pulse Width controls allow
independent adjustment of the
waveshape. (At 0, the sinewave
becomes a sawtooth with a fast
rise and slow fall.) The Depth con-
trols provide adjustment of the
chorus from 0-100%.

Detune (M)
Detune effects are useful for
thickening up sounds by adding
delayed/pitch shifted versions of
the original source. They can be
particularly effective when used to
simulate double-tracking. They
are also great alternatives to cho-
rus effects as a detuner can add
the richness of a chorus effect
without the audible sweep caused
by the chorus rate. Detuners are
also traditionally used to turn a six-
string guitar into a twelve-string, or
an in-tune piano into a honky-tonk.
The MPX G2 detuner is optimized
to provide very fine amounts of
pitch shift.

As the detune effects use up relatively few processing resources, they can be combined with
reverb and many other effects. When creating effects that don’t require pitch shifting by large
intervals (semitones) the detuners are the most efficient choice.
Detune (M) is a single-channel
detuner that creates a pair of sig-
nals, pitch-shifted up and down
from the input. The pair is always
mixed together, and presented
equally to the outputs.

Comb 1 and Comb 2
Comb 1
The Comb effects work by com-
bining the original input signal with
a micro-delayed version. The tiny
delay difference between the two
signals causes certain frequen-
cies to be cancelled or reinforced
when the two are combined. The
result is a highly colored version of
the original source. The coloration
can be “tuned” with the Comb
(Comb1)or Depth(Comb2). Low
and High pass filters are included
so you can limit the frequency
bandinwhichthecombingoccurs.
Comb 1 is a mono comb with
single-polelowand high cutfilters.
There are two ways to get the
comb effect. The first is to set mix
to100%(wet),thensetNotchto50
or -50. This essentially creates a
band-limited signal (limited by
LoCutandHiCut)whichisthenrun
through a comb. You can also set
mix= 50%, Lvl = 0dB, and Notch=
+100.Inthiscase,theband-limiter
is part of the comb. In this version,
the effect produces shallower
notch depths outside the band-
limit region.

The Effe c ts a nd Pa ra m e te rs
The Delay effects include delay, echo, looping and ducking effects. Delays are high
quality digital delays. Echoes are similar to delays, but low-pass filters have been added
to simulate the high-frequency rolloff that occurs naturally in acoustic echoes and in
echoes created with analog tape.
Delay Effects
All MPX G2 Delay effects allow you to choose how delay times will be displayed. Select
any Time parameter and press Options. The following choices are available for each
Time parameter:
ms: time is displayed as milliseconds (delay time is fixed)
feet: time is displayed as feet – the equivalent distance from a sound
source required to produce the delay (delay time is fixed)
meters: time is displayed as meters – the equivalent distance from a sound
source required to produce the delay (delay time is fixed)
echoes/beat: time is displayed as a rhythmic ratio of echoes per beat (delay time
varies with Tempo and can be changed at any time by pressing TAP
twice.)
TAP ms: time is displayed as milliseconds (new delay value can be “tapped in”
when this Time value is displayed for editing).
Another feature shared by all MPX G2 Delay effects is Fbk Insert. This option of the
feedback parameter allows you to route the outputs of another effect block to the delay’s
feedback input. If the other block is after the delay block, Fbk Insert will place it inside the
delay/echo feedback loop. This powerful feature is the key to obtaining many classic
effects.

Reverb Effects
The MPX G2 Reverb effects provide a full suite of reverberation and ambience
algorithms. All of the reverbs are true stereo in that differerent processing is applied to
the left and right input signals. Dedicated processing resources are allocated to the
reverb effects so that you can always load any reverb into any program, regardless of
what other effects are loaded. The MPX G2's Global Reverb function allows reverb tails
to ring out through program changes. (See Global Effects in Chapter 5: System
Controls.)
Chamber
The Chamber effect produces
an even, relatively dimensionless
reverberation, with little change in
color as the sound decays. The
initial diffusion is similar to the Hall
effect, but the sense of space and
size is much less obvious. This
characteristic, along with the low
colorofthedecaytailmakesCham-
ber useful on a wide range of ma-
terial.Itisespecially usefulonspo-
ken voice, giving a noticeable in-
crease in loudness with very low
color.

used to add a room sound to re-

room surfaces, with random re-
flections, a gradual decay of over-
all level, and a gradual narrowing
of the bandwidth. DTime settings
can be varied to create larger or
smaller spaces while variations of
DLvl and Rt HC correspond to the
hardness of the imaginary reflect-

At its simplest, equalization is the process of cutting and boosting certain
frequencies to make portions of program material more or less audible. This is
generally accomplished by combining filters which affect a specific “band” of
frequenciestogether withgain controls.Thethreetypes offilters commonly used
to perform basic EQ functions are: High Cut, Low Cut and Bandpass/Notch.
EQ Effects
High cut filters remove frequencies above a fixed level. As this allows frequen-
cies below the threshold to pass through unchanged, high cut filters are also
commonly referred to as “lowpass” filters.
High Cut
Low cut filters, which remove frequencies below a fixed level and allow higher
frequencies to pass through are also known as “highpass” filters.
Bandpass/Notchfilters allow only a certain rangeof frequenciestopassthrough
without attenuation. They are plotted as curves, with a peak (or dip in the case
of notch filters) at the center frequency.
Low Cut
Shelf filters
When a specific frequency value is selected for cutting or boosting, and
compensating gain controls are provided, a shelving filter is created, with
gradual build up of the boost or cut to the selected frequency, followed by a
levelingoffbeyondtheselectedfrequency. Whentheeffect ofthefilter is plotted,
it resembles a shelf, with constant levels of boost or cut preceding and following
the “knee” or “corner point” at the selected frequency.
A typical application of these filters uses 2-band equalization with two shelf
filters, one low and one high, to provide bass and treble tone control. These two
filters affect only the high and low frequency signals, leaving the center
frequencies unaltered. Adding a third or fourth band of equalization in the form
of midrange bandpass filters provides more control over those frequencies
where hearing is most sensitive, and where most of the energy in music exists.
(500Hz-4kHz). Thesemidrangebandspeak, or dip, at acenter frequency which
can be varied to provide much greater control over different aspects of the
sound, allowing for bass ortreble rolloff todecreaseboominess, thickensounds,
reduce noise, or increase brightness.

Parametric EQ
Parametric equalizers provide boost and cut controls, sweepable center fre-
quencies, andadjustment of“Q”, or thebroadness or sharpnessoftheEQcurve
—alloftheparametersofequalization.Thisabilitytobroadenornarrowthepeak
at certain frequencies allows specific sounds to be accented or diminished with
minimal effect on adjacent frequencies. As all equalization has potentially
adverse side effects on program material, this ability to precisely adjust only
specific frequencies has the advantage of minimizing the amount of EQ applied
toprogram material. It alsoallows thecreationofspecific effects suchassharply
narrowed EQ curves (notches) which are useful for feedback control or removal
of specific noise artifacts.

The Effe c ts a nd Pa ra m e te rs
EQ Tips (for tweakers only)
About “Q”
Q is a measure of the sharpness of
an EQ curve. The larger the Q value,
the sharper the curve. In some situa-
tions it is convenient to think of Q in
termsofbandwidthin octaves.Some
examples:
Q
Bandwidth
0.1 approximately 6 1/2 octaves
0.4 approximately 3 octaves
0.7 approximately 2 octaves
1.4 approximately 1 octave
2.9 approximately 1/2 octave
4.3 approximately 1/3 octave
5.8 approximately 1/4 octave
7.2 approximately 1/5 octave
8.7 approximately 1/6 octave
10.0 approximately 1/7 octave
MPX G2 Parametric EQ: Gain
Q=1.0 Gain=+24dB, +18dB, +12dB,
Fc=1000Hz
+6dB, 0dB, -6dB, -18dB,
-24dB, -36dB, -72dB
Therearemathematicallimitsto how
small the Q value can be in MPX G2
EQeffects. Foranygiven frequency,
the Q must be greater or equal to the
frequency divided by 10,000. For
example if the frequencyis5kHz, the
actual Q value won’t go below 0.5.
(The MPX G2 will allow you to dial in
lower values, but the actual Qwill not
go below the mathematical limit.)
For most shelving applications, Q
should be set very low (Around 0.2).
As you increase the Q, the filter be-
comes peaky, but a dip also devel-
ops just outside the passband. For
many applications, a bandpass or
band cut filter with a moderate Qand
a low (or high) center freq will prove
sonically superior to the shelving fil-
ter.

Making a Low Pass Filter
To make a two-pole low-pass filter,
startwith ahighshelf, andsetGain to
-72 (effectively off). This creates a
lowpassfilterwithacornerfrequency
at Fc. A Q of 0.7 makes a flat pass-
band. Higher Q settings produce a
peak at Fc, and lower Q settings
produce a droop.

In general an LFO is a source whose output cycles constantly between 0, 127 LFO1 and LFO2
and 0. Each LFO produces four simultaneous output waveforms: Sine, Cosine,
Triangle and Pulse. Rate controls how fast the output cycles — you can set the
LFO Modes
Off:
On:
LFO is disabled (OnSrc and
OnLvl are ignored)
rate as either a frequency (such as 3Hz) or as a rhythmic value (such as 2:3
cycles per beat). A Depth parameter scalesthe output range. Several additional
parameters make the MPX G2 LFOs very flexible. Mode, OnSrc and OnLvl
allow youtoturn theLFOs onandoffin different ways basedontheoutput levels
of other MPX G2 controllers. PW allows you to dynamically modify the shape
of LFO waveforms. Phase lets you change the phase of the Cosine relative to
the other waveforms (Sine, Triangle, and Pulse).
LFO is always on (OnSrc
and OnLvl are ignored)
In the remaining modes, when the
value of OnSrc rises above or falls
below the value of OnLvl the LFO is
switched on and off as follows:
Latch: LFO toggles on and off
whenever OnSrc value rises
above OnLvl
NOTE: In all modes, the LFO completes its current cycle before stopping.
The first press of Tap resets the LFOs.
Gate: LFO stays on while OnSrc
value is greater than OnLvl
Once: LFO sweeps through one
complete cycle when OnSrc
value rises above OnLvl.
(During the sweep, further
changes of OnSrc value are
ignored.)

195 Little Amp
A tiny “hog-style” amp with a 6 inch speaker.
196 Phone Filter
Overcompressed and drastically EQ’d, this is an effective way to accent a part or phrase
within a mix.
197 Vibro Cab
The original Vibro Tone guitar cabinet had a rotating baffle in front of a 12 inch guitar
speaker. Itproduced aswirlingsoundby sprayingthe speaker output throughthe topand
sides of the cabinet as the baffle rotated. A built-in crossover sent high frequencies back

chorus and auto panners to create the effect. A/B toggles between slow and fast rotary
speeds
198 Cordovox
The original Cordovox had a rotating baffle cabinet. It had an 8 inch speaker which had
pretty limited bass and treble frequency response and distorted quite easily. Sound was
projected out of the top and sides of the cabinet. Our version uses the preamp to recreate
the amp and speaker characteristics. The sound is gritty, so when you dig in you get a
lot of distortion but, as you play lighter or switch to less powerful pickups, you get cleaner
sounds. Stereo chorus and auto panners are used to create the swirl. A/B toggles
between slow and fast rotary speeds.
199 Rotary Cab
A Leslie speaker has separate rotating elements for treble and bass. Our version adds
Chamber reverb to put the cab in in a small room. The preamp sound is clean with a little
bit of grit, so when you dig in you get some distortion. A/B button controls fast and slow
speeds of the rotary speaker.
Programs 200-209 are designed to give you a suite of realistic reverberation and
ambience treatments for electric and acoustic guitar tracks. Think of this as adding

Studio Spaces
(Stand Alone)
Each program can be used stand alone for tracking — just plug in your guitar and record
direct through the MPX G2 built-in preamp. (You can easily change the preamp by using
Copy Effect in Edit mode to copy the preamp from any other program.
These programs can also be used for tracking with an external preamp as well as for
processing pre-recorded tracks during mixdown.
When using an external preamp, connect its outputs to the MPX G2 Insert Return jacks.
Use the MPX G2 Speaker Simulator to fine tune the raw preamp sound.
To process pre-recorded tracks, connect the MPX G2 Insert Returns to your console’s
sends as you would any stereo processor. Turn off the MPX G2 Speaker Simulator and
Noise Gate, and set Post Mix (in Edit: Mix mode) to 100% wet.
200 TrackingRoom
This program features the Ambience effect. Use it to add room sound without adding the
decay associated with reverberation. This is a great way to add “air” to when you’re
tracking direct. Stereo EQ(in the Soft Row) lets you fine tune the sparkle and boom (high
and low frequencies).

201 Acoustic Room
This program is designed for acoustic guitar. The reverb blooms nicely behind the notes
thanks to a compressor on the reverb inputs.
202 Jazz Club
A moderate, but dense, reverb that fattens up cleanly articulated melodies and chords.
Be sure to experiment with reverb predelay (P Dly in the Soft Row). Use it to allow the
attack of notes to stay “in your face”
Programs 203-205 can be used individually or in any combination. Each is made up of
amedium-sized, live roomhungwithnearandfarmicrophonepairs. RvbMix controlsthe
overall direct-to-room sound mix. The Far Mics parameter provides an independent
control for the level of the distant microphones. You’ll find these parameters, as well as
PDly and the other important reverb tweaks in the Soft Row.
203 Solo Room
A high-gain amp in a live room with a direct feed, as well as near and far microphones.
Both sets of mics are stereo pairs. The overall image is balanced in the stereo field.
204 RhythmRoom L
A clean amp in the same live room as Solo Room, but with the near mics panned left of

attacks, and shifts to the right as the notes fade.
205 RhythmRoom R
SimilartoRhythmRoomL,withthepanningofthemicsreversed.Initialattacksareheard
on the right side, then shift to the left as the notes fade.
206 MicPlacement
This program lets you vary the position of a close microphone in front of high-gain amp.
(Use the Placement parameter in the Soft Row.) Altering the position will create phase
differences that change the overall timbre of the sound.
207 Tape->Plate
This combination of tape predelay in front of a plate reverb can be heard on most of the
classic rock recordings from the 60’s and 70’s. A/B changes the tape delay from 15ips
to 7.5ips.
208 PCM 60 Room
This program recreates the settings of a Lexicon PCM 60, tweaked for guitar.
209 Gated Verb
More of an effect than a natural space, gated reverb can be quite useful to thicken up
rhythmic parts without spilling over into the rest of the mix.

up too, but are bypassed when the program loads. Press Delay to bring them in.
212 Stereo Phaser
Two separate OrangePhaser effects independently process left and right channels.
213 Env AutoPan
RedComp pumps up the signal before it gets to Preamp. From there, it runs through
reverb auto pan, chorus and delay. The twist here is that the panner rate is envelope-
controlled. Play a big chord and listen to what happens as it rings out. The MPX R1 pedal
controls the depth of the panning. Tap sets the delay rhythm.
214 Env AutoWahs
An alternative take on standard tremolo effects. Dual auto wahs are controlled by your
playing dynamics. The MPX R1 pedal controls the depth of both wahs.
215 EnvFilter LP
A very funky, synth-like effect, reminiscent of a Mu-tron III set to “LP”. The dynamics of
your playing opens and closes a resonant filter. A/B brings in some stereo echoes. The
MPX R1 pedal controls the effects sensitivity to your playing dynamics. The Toe Switch
turns the effect on and off.
216 Dual Delay
Basic, but essential. Left and right channel delays — each with independent delay time
(up to 10 seconds), level, pan and feedback controls. Everything is in the Soft Row for
instant access. You can make one or both of these delays tempo-controlled. Just press
Options with the Time parameter displayed, select “echoes:beat” and press Options

219 InfiniteEcho
A variation of Analog Echo that adds the BlueComp compressor and Detune(M) to the
analog feedback path. The compressor limits the feedback signal so that the effect never
runs away. You can increase the number of repeats by turning up the front panel tone
controls as well as altering the Delay Fbk parameter in the Soft Row. Note that, as Insert

236 Pitch Cascade
This special effect is created by putting a dual pitch shifter in the feedback loop of a dual
delay. Tap sets the delay rhythm. After going through the delay, the notes are pitch
shifted. (A/B selects between up a fifth/down an octave and down a fourth/up an octave/
.)Then the pitch-shifted notes are recirculated through the delay and pitch-shifted again.
The recirculation is controlled by the XFbk1 and XFbk2 parameters. (They’re in the Soft
Row along with delay time and other goodies.)
237 Octaves
Use a pedal to fade two additional harmony voices in and out. A/B alternates between
tunings. A=one octave up (doubled). B=one ocatve down and two octaves down.
238 Pdl 2nds
A pedal gives you whole step bends. A=bend up. B=bend down.
239 E Maj/Min 3
Tune up and play melodies in the Key of E. The DiatonicHmy effect automatically
harmonizes your notes in thirds. Use A/B to alternate between E Major and E Minor
(Aeolian). You can change to any other key by adjusting the value of the Key parameter
— you’ll find it in the Soft Row.

In a low-voltage, or "brown-out" condition (less than 40VAC), the MPX G2 will
freeze in its current state. None of the controls will have any effect. When power
returns to a normal level, the unit will reset itself as though it had just been
powered on. If the unit does not reset itself, turn the power OFF, then ON to
resume normal operation.
Low Voltage
Overheating
Temperature extremes may cause the MPX G2 to exhibit unpredictable behav-
ior. If the unit has been subjected to temperatures below 32°F (0°C) or above
95°F (35°C), it should be turned off andallowed to return to normal temperature
before use. Theunit maybedamagedbyexposuretotemperatures below -22°F
(-30°C) or above 167°F (75°C), or by exposure to humidity in excess of 95%. If
a unit exposed to such conditions fails to operate after it returns to a normal
operating temperature, contact your local service representative.
The MPX G2 doesn't respond to MIDI Program Changes.
Common MIDI
Problems
The MPX G2 and connected devices must be set to matching MIDI Channels,
or the MPX G2 must have OMNI selected for receipt of MIDI messages. In the
System mode MIDI menu, check the Receive control for the MIDI Channel
selected, as well as the MIDI Channel of the transmitting device.
Make sure that Pgm Change in the System mode MIDI menu is set to On. See
Chapter 6: MIDI Operation for Program Change messages which may be
ignored by the MPX G2.
Check MIDI In/Out connections between the units.
MIDI Program Change numbers are off by 1.
TheMPXG2transmits andrecognizesProgramChangemessages 0-127. MIDI
devices which transmit 1-128 rather than 0-127, will be off by 1.
