Foreword When we started development on the MPX G2 Guitar Effects Processor and the MPX R1 MIDI Remote Controller, we knew we were designing for the most discriminitating guitarists — players whose tonal foundation is based on this nocompromise 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.
Introduction Thank you for your purchase of the MPX G2 Guitar Effects Processor. The MPX 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.
An A/B glide function is also available from the front panel — and of course we've designed presets to show this function off to its fullest. Whenever the A or B LED is lit, press the A/B button to activate the glide. When you want to create your own versions, you'll find A/B available as an internal controller in Edit mode along with two LFOs, an Envelope, and more. The A or B LED will light whenever a program with A/B Glide is loaded. Press A/B to activate a parameter glide whenever these lights are lit.
Product Overview 1 Product Overview The Front Panel Program* Activates Program Mode where you can select and load programs and see which effects are active in any program.

MPX G2 User Guide Signal Flow Lexicon Following are diagrams showing signal flow in the MPX G2 Pre-Gain and PostGain 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.
Product Overview 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.
MPX G2 User Guide Lexicon Insert Send The MPX G2 Insert Send is always active. When Gain 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 through a programmable level control (Edit mode: Mix: Send Level) and analog noise gate before leaving the unit via the Insert Send jack.
Product Overview The MPX G2 Main Outputs are set to stereo at the factory. When connecting the MPX G2 to an external device with a mono input (such as a mono effects loop return), set the Main Outputs for mono as follows: 1.Press System twice. The display will show System select: Audio. 2.Press > to select Audio OutputMode. Connecting the Main Outputs to Mono Input 3.Turn the knob to change the setting from Stereo to Mono. 4.Press Program to return to Program mode.

Basic Operation 2 Beginning with a menu tree to guide you through the major areas of the MPX G2, this chapter focuses on the basics that you want to get to first — finding, loading, tweaking and storing programs.
MPX G2 User Guide Lexicon Loading and Playing Pressing the front panel Program button accesses the MPX G2 library of 300 with Programs presets and user programs. In this mode, you can select and load programs, select database sorting criteria and access the "Soft Row" — a selected set of the most useful parameters for each program. You can also access Tap, A/B, Mix and Patch functions, as well as selecting and bypassing effects in the program. Each of these is described in this section.
Basic Operation The front panel Effect buttons light to show you which effect blocks are active. — When you're scrolling through programs, they'll change to show you the effects in any displayed program. Once you stop scrolling, they'll return to display of the effects that are active in the currently loaded program. Effect Bypass To bypass any active effect, press its button. The light will turn off and the effect will be bypassed. Press the button again to make the effect active again.
MPX G2 User Guide Lexicon 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 pregain path, only the post-gain path or both paths. Bypass behavior for each path can be independently programmed as well.
Basic Operation A/B is a unique glide function which allows you to "morph" between selected parameters. Most effect parameters (or groups of parameters) can be patched to the A/B controller. Once a parameter is patched, the A/B controls in Edit mode allow you to select the rate at which you want to glide from A to B and from B to A when the front panel A/B button is pressed.
MPX G2 User Guide Using the DataBase In Program mode ... Lexicon The MPX G2 has a database sorting function which allows you to sort and search for programs in various categories. This is a great timesaver when you're looking specifically for guitar effects, or EQ effects, or for EQ effects for guitar. When shipped, the DataBase sorting option is set to "Sort by number", allowing you to use the knob to scroll through all of the 300 programs in numerical order in Program mode.
Basic Operation Once you've made changes to a program, such as turning an effect off, or modifying any of the soft row parameters, an edit indicator in the display (•) will appear in front of the program name. This identifies the program as having been altered since the last store procedure. This edit indicator, along with all of your changes, will disappear when you load another program. To save your changes, press Store.

Editing 3 This chapter describes all of the MPX G2 edit functions. As the first thing you are likely to want to modify in a program are its effects, this section starts there and then moves on to all of the functions available in Edit mode. Editing Effect Editing To edit any effect, press Edit, then press an Effect button to view all of the Effects of that type, and to edit the parameters of the current Effect. The display will show the Effect type and the name of the currently loaded Effect .
MPX G2 User Guide Coarse and Fine Editing of ms and Hz values Parameters whose values are displayed in ms or Hz have overall ranges of more than 1000 units. When you select one of these parameters for editing, you’ll notice that either the left or right portions of the value can be selected for editing. For quick, coarse adjustments, select the left portion of the value. For fine adjustments, select the right portion of the value.
Editing The MPX G2 Edit menus give you access to all of the controls you need to create your own programs. Whether you want to view the meter display, re-route the effects in a program, or create an entirely new sound, you will find the tools you need in this section. The MPX G2 Edit Menus The complete Edit mode menu structure is shown below, followed by detailed explanations of each main menu selection. Press Edit to enter the main Edit menu.
MPX G2 User Guide Lexicon Mix Press Edit to enter the main Edit menu and use the knob to select Mix. The display will show Mix and Level labels on the upper line, and the current settings on the lower line. One of the values on the lower line will be flashing to let you know which is selected for adjustment. Use the < and > buttons to select Send Level, Post Mix and Level, or to step to the Mix and Level controls for any active effect in the currently running program.
Editing 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 the MPX 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.
MPX G2 User Guide Automatic Speaker Sim Routing All routing to and from the Speaker Simulator is automatic, based on which Insert Return jacks are used and whether or not Split Preamp is loaded into the Gain effect block.
Editing The MPX G2 has two integrated noise gates, one analog and one digital. Both are driven by the direct signal. The gates share a common set of parameters 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. This allows you to gate the analog signal connected to your guitar amp. The attack and release times of the analog gate are fixed (both are preset to be very fast).
MPX G2 User Guide Lexicon Meters The G2 has a built-in meter array that allows you to simultaneously view guitar input level, main output levels as well as the levels of all individual effects blocks, except Gain. The meters are displayed in fixed order: Input, Effect 1, Effect 2, Chorus, Delay, Reverb, EQ, Output. Effect blocks are indicated by their number or inital letter.
Editing Selecting Effect Order from the Edit menu allows you to put the seven MPX G2 Effect blocks in any order you wish. Press > to display the current ordering and routing configuration. An ordering display such as the one shown below will appear. Effect Order An underscore identifies the Effect block which is selected for moving to a new location. 1=2=g=C=D=R=E Effect types are represented by their initial letters or numbers.
MPX G2 User Guide Routing Map Lexicon 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 connections between the MPX G2 effect blocks. Use the Routing Map to change connections between individual effects and also to change the overall routing configuration of all seven effect blocks as a group.
Editing 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 mono in, and stereo or mono out, depending on the particular effect. The path through an MPX G2 analog Gain effect is slightly different: Note that there is no wet/dry mix path for the analog effects and that these effects are mono in and mono out.
MPX G2 User Guide How to Change Routing Connections Lexicon The routing page lets you alter the connections between the inputs of the selected block and the outputs of the blocks in front of it. It is easy to think of these connections as patch cords connecting the different blocks. There are five possible connections for the inputs of any block. On the Routing Map, use the < and > buttons to select any upper case letter. (Lower case letters indicate inactive effects, which cannot be edited.
Editing In the following examples we’ve selected three presets that demonstrate creative applications of the routing and connection capabilities of the MPX G2. Example 1: Program 198 Cordovox (Stand Alone) Routing Examples Cordovox Routing Map 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.
MPX G2 User Guide Example 2: Program 61 Octave Fuzz (Amp Input + FX Loop) Lexicon Octave Fuzz Routing Map The Octave Fuzz program combines sub-octave and Octavia-style effects with analog distortion. When connected to the high gain input of a guitar amp, many classic Octave Fuzz effects can be produced. The Input block option is set to Split, to create two parallel paths. The paths are joined together at the input of the Gain block by setting its option to Merge.
Editing Example 3: 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).
MPX G2 User Guide Lexicon 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.
Editing This Edit menu selection provides controls for making individual adjustments and assignments for each of the MPX G2 internal controllers: Knob, LFO 1, LFO 2, Random, A/B and Env. This section describes controller editing. For detailed information on the controllers themselves, see Chapter 8. Controllers Making controller adjustments is straightforward. The first of the controller selections (Knob) is shown here as an example.
MPX G2 User Guide Lexicon Tempo 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. 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.
Editing Tempo is expressed in BPM. This control allows you to specify the value of the beat (Eighth, DottedEighth, Quarter, DottedQuarter, 2-126 Beats). If, for example, you select EighthNote here, each Tap will be interpreted as an eighthnote. If you select QuarterNote here, each Tap will be interpreted as an quarternote. (The factory default is QuarterNote.) Beat Value Option: Tap Average Press Options to access the Tap Average control which allows you to average the last 2-8 Taps.
MPX G2 User Guide Soft Row Parameter Assignment Lexicon Parameters that you want to assign to the Soft Row for easy access are selected from the Edit mode Soft Row Assign menu. Use the < and > buttons to select any of the ten Soft Row positions. Turn the knob to scroll through and assign parameters to the selected position. (All parameters in the current program are available for assignment. The example below shows the FX 1 Level parameter assigned to the first position in the Soft Row.
Editing When you select DataBase, the display will show a selection like the one below. The upper line identifies the selection category (guitar style, effect type or application type. DBase App Type FX Loop: NO The lower line shows the Style, Effect or Application type and the current DataBase selection (YES or NO). The selected field will flash to let you know which is selected for changing. The item on the lower line of the display which is selected for adjustment will flash.
MPX G2 User Guide Lexicon Copy Effect Copy Effect lets you take an Effect from any program in the MPX G2 and copy it into the current program. To use this function, select Copy Effect from the Edit menu. Press the > button and use the knob to display any of the MPX G2 programs. The front panel Effect buttons light to show you which effect blocks are active in the displayed program. Press any lit button to display: The name of the effect from the displayed program appears on the upper line.
Patching 4 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.
MPX G2 User Guide Lexicon Selecting a Source From the patch number display, press > to step to the patch Source and and Destination Destination assignment screen. The display will show the current Source Patch Sources All Sources are the same in the sense that each generates an output value in the range of 0-127. The output value is used to increase or decrease the setting of a Destination parameter value.
Patching With Src selected, pressing Options will allow you to specify range limits for the controller you have selected. With the following screen displayed, use the < and > buttons to select the Min, Mid or Max field, and the knob to set the value from 0-127. The default settings of Min=0 and Max=127, cause the parameter to be controlled linearly by the controller. Reversing these values (Min=127 and Max=0) will establish inverse control over the parameter.
MPX G2 User Guide MIDI Learn — Automatic Controller Assignment Lexicon You can have the MPX G2 automatically recognize a MIDI controller as a patch Source, as well as assigning its MIDI Receive channel to match any controller with the MIDI Learn function. From the Source Activity screen, press > to access the MIDI Learn screen. With this screen displayed, simply move any active MIDI controller to automatically assign it as the Source for the current patch.
Patching For most applications, the default full-range Destination values are all you will want, as these allow your selected Source to exert direct control over the full range of parameter values. In other cases, you may want to adjust the Destination values to a more limited range, or establish a nonlinear relationship between the controller and the parameter values.
MPX G2 User Guide Lexicon Linear or Nonlinear From either of the Destination Values screens, pressing Options will allow you Control to set the control relationship between your Source and Destination, temporarily suspend the current patch, or to clear one or more patches entirely. Patch Values > Unchanged Pressing Options from either of the Destination value screens lets you determine the control relationship between the Source and Destination, and clear any or all patches.
Patching Continuing to press > will step you to the Suspend option. Selecting Suspend temporaily suspends the patch until such time as you return to the Patch System Destination Option and select Unsuspend. Suspending and Clearing Patches Continuing to press > will step you to the options: Clear 1-5, and Clear All. These allow you to select any or all patches to be cleared.

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.
MIDI Operation Reception of MIDI Program Change and Bank Select messages can be selectively enabled/disabled from the System mode MIDI menu. The manner in which the MPX G2 interprets these messages is determined by the value of this parameter as follows: Program Change Messages 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.
MPX G2 User Guide Lexicon Automation SysEx Automation The MPX G2 will transmit SysEx automation messages when the System mode MIDI Automation parameter is set to On. Virtually all changes made by front panel operations are transmitted as MPX G2 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 Effects and Parameters 7 The MPX G2 contains a library of 76 effects, each of which is described in detail in this section. The Effects and Parameters The effects are organized into seven effect types corresponding to the Effect Selector buttons on the front panel (Gain, Effect1, Effect2, Chorus, Delay, Reverb and EQ). All of the effects available in each category are listed below.
MPX G2 User Guide Lexicon Notes on Different effects require different amounts of MPX G2 processing. The following Combining Effects notes should be kept in mind when creating new combinations of effects in a program. 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 Effects and Parameters Gain Effects Tone Lo ± 25dB Clean low frequency boost/cut Mid +12/-25dB Clean mid frequency boost/cut Hi ± 25dB Clean high frequency boost/cut InLvl -64 to 0dB Input level (headroom) Level 0dB to 64dB Output level Tone is a set of analog Tone controls which can be used as a clean-boost stomp box in front of your amp, or as a simple clean preamp when the MPX G2 is used without an external guitar amp.
MPX G2 User Guide Lexicon Screamer Screamer is an analog model of a vintage Tube Screamer overdrive (powered by a fresh carbonzinc battery). Care has been taken to make the behavior of this effect accurate both sonically and electronically. The ranges of Drive and Tone match those of the vintage effect and it will push your amp into high gear just like the original. We’ve also added Lo, Mid and Hi tone controls.
The Effects and Parameters Overdrive Lo ± 15dB Low frequency boost/cut Mid ±15dB Mid frequency boost/cut Hi 0-15dB High frequency boost InLvl -64 to 0dB Input level (Drive sensitivity) LoCut 0-20 Pre-Drive low frequency roll off Feel 0-64 Overdrive dynamics Drive 0-40 Amount of overdrive Tone 0-25 High frequency roll-off (Post-Overdrive) Level 0dB to 64dB Output level A more aggressive overdrive effect than Screamer, Overdrive is designed to be used as a stomp box — to push a cl
MPX G2 User Guide Lexicon Distortion Need more than just Overdrive? Distortion provides more than 100dB of analog gain — and it has an additional set of Bass and Treble controls following the distortion stage. Although not based on any particular pedal, this effect has a sonic kinship with several classic distortion pedals and fuzz boxes.
The Effects and Parameters 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 another will pay off when you’re searching for "the sound". Be aware that this preamp can produce well over 120dB of analog gain.
MPX G2 User Guide Lexicon Effect1 and Effect2 Effect descriptions for all of the effects contained in Effect1 and Effect2 are combined in this section. 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 Effects and Parameters Shift (M), Shift (S) and Shift (D) Shift (M) Shift (S) Shift (D) Mix 0-100% Level Off, -89 to +6dB Dry/Wet ratio Amount of effect in the processed signal Tune -4800 to +1900 cents Pitch shift (Optimize) 0-100 Adjusts the amount of delay in the pitch shifter Glide Off, On Coarse, fine resolution of pitch shift These effects use more processing resources than the detuners. Shift (S) and Shift (D) are among the largest effects in the MPX G2.
MPX G2 User Guide Lexicon Diatonic Hmy DiatonicHmy is an “intelligent” pitch shifter. The effect will automatically shift the pitch of an incoming monophonic notes to the correct harmony note in the selected key and scale. You select the key and scale — (E major, A minor, etc.) and harmony interval (up a 3rd, down a 6th, etc.). When an out of key note is detected, it will be shifted by the same interval amount as the last in-key note.
The Effects and Parameters Panner The Panner effect has the left input panned to outputs with Pan 1, right input with Pan 2. Because all the parameters of this effect are interpolated, this can be used to add interpolated outputs to effects which have non-interpolated output levels.
MPX G2 User Guide Lexicon Tremolo (M) and Tremolo (S) In Tremolo (M), the left and right inputs are mixed together, then a local sinewave generator modulates the volume. In Tremolo (S) the left input is modulated by a local sinewave generator before going to the left output. The right input is modulated by sin, cos, -sin, or -cos, depending on the Phase parameter. These are the smallest mono and stereo effects with interpolated output level controls.
The Effects and Parameters CustomVybe Mix 0-100% Dry/Wet ratio Level 0ff, -89dB to +6dB Amount of effect in processsed signal Rate 0-50Hz or Custom Vybe rate or period ratio This custom version of Univybe has additional parameters with extended ranges. The Rate can be set to any speed from 0-50Hz. It can also be set in cycles/beat, allowing you to tap in the sweep rate. When Depth is set to 100%, the effect is about twice as pronounced as the original.
MPX G2 User Guide Lexicon OrangePhase The sound and rate of this phase shifter are modeled on a vintage MXR Phase 90 stomp box — a signature component of the early Van Halen sound.
The Effects and Parameters Blue Comp Mix 0-100% Dry/Wet ratio Level 0ff, -89dB to +6dB Amount of effect in processsed signal Sense -72dB to +24dB Sensitivity (Pre-Compressor level) Thrsh -83dB to 0dB Gain reduction threshold Gain -72dB to +24dB Post-Compressor level ATime 0-2000 ms Attack time RTime 0-2000 ms Release time Blue Comp is a recreation of another popular compression pedal, the CS-3.
MPX G2 User Guide Lexicon OctaBuzz OctaBuzz is a very simple effect that mimics the “full wave rectifier” circuit used in many octave fuzz pedals, like the Octavia. Another signature Hendrix effect, (Purple Haze, Who knows, etc.) it is not a pretty sound, and requires a little effort to make it sing. Play single notes above the 12th fret to get a screaming tone an octave higher. Single bass notes can produce ring modulator-like sounds. Double-stops and chords produce wierd electronic hash.
The Effects and Parameters SweepFilter Mix 0-100% Level* Off, -89 to +6dB Dry/Wet ratio Amount of effect in the processed signal Fc* 20-20000Hz Corner frequency offset of filter FRes* 1-100 Filter resonance: 7=a maximally flat filter Mod* 20-20000Hz added to corner frequency offset to produce corner frequency Scale* -100 to +100% scales Mod Pan* 50L to C to 50R Left/right pan control SweepFilter simulates a Moogtype resonant low-pass filter.
MPX G2 User Guide Lexicon Wah 1, Wah 2 and PedalWah1, PedalWah2 Wah is a mono wah filter modeled after two classic wah-wah pedals. With Sweep selected, press Options to select Model C (CryBaby) or Model V (Vox). These models capture both the characteristic signature and nonlinear pedal response of the original pedals. Bass allows you to 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 keyboards.
The Effects and Parameters Volume (M), Volume (S) and Volume (D) Volume (M) Volume (S) Volume (D) Mix 0-100% Dry/Wet ratio Level* Off, -89 to +6dB Amount of effect in the processed signal Vol* 0-100% Amount of effect in the processed signal The Volume effects can be placed in front of, or behind, other effect blocks to provide smooth level control through a 95dB range.
MPX G2 User Guide Lexicon Test Tone Test Tone is an audio sine wave generator with its output quantized to correspond with the pitches of a chromatic scale (A = 440 Hz) over a nine-and-one-half octave range. It is provided primarily as a convenient way of generating test tones and tuning references. Bal controls the relative level of left and right output attenuation. When Bal=-50, the left output has no attenuation, and the right output is fully attenuated. When Bal=0, neither output is attenuated.
The Effects and Parameters The chorus effects are generally used to enhance a sound by modulating delay times and/ 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.
MPX G2 User Guide Lexicon 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 chorus 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 sixstring guitar into a twelve-string, or an in-tune piano into a honky-tonk.
The Effects and Parameters Flanger (M), Flanger24 (M) and Flanger (S) Flanger (M) and Flanger24 (M) Flanger (S) Mix 0-100% Level* Off, -89 to +6dB Amount of effect in the processed signal Rate 0-50Hz or 1:24-24:1 cycles/beat Flange rate or period ratio (Rate Units) Dry/Wet ratio Selects frequency or cycles/beat PW 0-100% Depth* 0-100% Flange pulse width Flange depth Phase 0°-270° In Flanger (S) sets the phase difference between the right and left flangers Res -100 to +100 Resonance
MPX G2 User Guide Lexicon Rotary Cab This effect simulates a Leslie speaker with one pair of stereo mics on the rotating low-frequency drum, and another pair on the rotating high-frequency horn. Bal sets the relative mix of Drum and Horn mics. Width controls the stereo spread of both pairs of mics. Rate and Depth 1 control the speed and depth of the rotating low-frequency drum. Rate 2 and Depth 2 control the speed and depth of the rotating high-frequency horn.
The Effects and Parameters Orbits Mix 0-100% Level* Off, -89 to +6dB Amount of effect in the processed signal Rate1 0-50Hz or 1:24-24:1 cycles/beat Left Mod and Pan rate or period ratio (Rate 1 Units) Dry/Wet ratio Selects frequency or cycles/beat PW 1 0-100% Left Mod and Pan pulse width Sync1 -120° to +120° Phase difference between left LFO Mod and Pan Dpth1* 0-100% Left Mod and Pan depth Rate2 0-50Hz or 1:24-24:1 cycles/beat Right Mod and Pan rate or period ratio (Rate 2 Units) O
MPX G2 User Guide Lexicon Centrifuge1 and Centrifuge2 Centrifuge1 The Centrifuge effects have a pair of modulated left and right delays routed into a single auto panner. In these effects, mod and pan rate and depth (Rate1, Depth1) are modulated by an additional set of rate and depth controls (Rate2, Depth2). These can create unique chorus and flanger effects with complex, undulating modulation rhythms.
The Effects and Parameters Comb 1 and Comb 2 Comb 1 Comb 2 Mix 0-100% Level Off, -89 to +6dB Dry/Wet ratio Amount of effect in the processed signal LoCut 100-10000Hz Corner frequency of the low cut filter HiCut 100-10000Hz Corner frequency of the high cut filter Comb 0-100 A microdelay which positions the notch Notch -100 to +100 Increases the audibility of the notch Ratio of filter and delay output levels: Notch -100 -50 0 50 100 Rate 0-50Hz or 1:24-24:1 cycles/beat (Rate Units) Filt
MPX G2 User Guide Lexicon Volume (M), Volume (S) and Volume (D) The Volume effects can be placed in front of, or behind, other effect blocks to provide smooth level control through a 95dB range. You can use them for dynamic input or output control, EQ input trim (helpful when adding large amounts of gain with an EQ effect), stereo to mono mixer, cross fade controls, volume pedal, etc. In Volume(M) the left and right inputs are mixed together, then sent to both outputs through a volume control.
The Effects and Parameters 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.
MPX G2 User Guide Lexicon Delay (M), Delay (S) and Delay (D) Delay (M) is a simple mono delay with feedback. Delay (S) is a simple stereo delay with feedback. Delay (D) is a dual delay with feedback, crossfeedback, independent output level adjusts, and panners.
The Effects and Parameters Echo (M), Echo (S) and Echo (D) The Echo effects are similar to the Delay effects, except the feedback inputs are sent through 1pole low-pass filters. Damp provides control over the cutoff frequency of the filter. (Increasing Damp lowers cutoff frequency.
MPX G2 User Guide Lexicon Looper In the Looper effect InMix controls the ratio of input to feedback into the delay. This parameter is ducked by the input level, so that louder signals route the input signal into the delay, and softer signals route the feedback signal into the delay. When Sense is at 0, no ducking will occur. At 100 the input will be ducked by even the lowest input levels.
The Effects and Parameters JamMan Mix 0-100% Dry/Wet ratio Level 0ff, -89dB to +6dB Amount of effect in processsed signal Size 0-20,000ms Loop size in ms (display only, this is set by pressing Tap) Fbk -100 to +100% Feedback level (defaults to 100% while looping) Clear Off, On Mutes and resets the loop when On Layer Off, On Adds new material on top of loop while On Replc Off, On Replaces existing loop with new material while On Delay Off, On Turns looper into mono delay while On Mu
MPX G2 User Guide Lexicon Ducker Similar to Looper, with the wet output getting quieter as the input gets louder. When Sense is at 0, no ducking will occur. At 100 the input will be ducked by even the lowest input levels.
The Effects and Parameters 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.
MPX G2 User Guide Lexicon Plate Plate effects were originally generated by large, thin sheets of metal suspended upright under tension on springs. Transducers attached to the plate would transmit a signal which would, in turn, vibrate the plate. Because the plate provided a denser medium than air, sounds broadcast through it would seem to be ocurring in a large open space. The Plate effect synthesizes the sound of metal plates, with high initial diffusion and a relatively bright, colored sound.
The Effects and Parameters Gate Mix 0-100% Dry/Wet ratio Level Off, -89 to +6dB Amount of effect in the processed signal Time 140-700ms Reverb time for mid and low frequency signals Link Off, On Scales Spred with Size Diff 0-100% Increase of initial echo density over time P Dly 0-250ms Delay inserted before the onset of reverberation LoSlp -16 to +16 Determines low frequency envelope shape HiSlp -16 to +16 Determines mid and high frequency envelope shape Xover 30Hz to 24.
MPX G2 User Guide Lexicon EQ Effects 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 frequencies together with gain controls.The three types of filters commonly used to perform basic EQ functions are: High Cut, Low Cut and Bandpass/Notch. High Cut High cut filters remove frequencies above a fixed level.
The Effects and Parameters 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 situations it is convenient to think of Q in terms of bandwidth in octaves. Some examples: Q 0.1 0.4 0.7 1.4 2.9 4.3 5.8 7.2 8.7 10.0 MPX G2 Parametric EQ: Gain Fc=1000Hz Q=1.
MPX G2 User Guide Lexicon 1-Band (M), 2-Band (M), 3-Band (M) and 4-Band (M) The 1-Band (M) effect provides a single band of double-precision parametric EQ. 2-Band (M), 3-Band (M) and 4Band (M) have two, three and four bands, respectively, of double-precision parametric EQ. Each effect has adjustable center frequency, Q, boost/cut and filter type (low shelf, band, high shelf).
The Effects and Parameters 1-Band (D) and 2-Band (D) 1-Band (D) has two bands of double-precision parametric EQ, one on each channel. 2-Band (D) has four bands of double-precision parametric EQ, two on each channel. Center frequency, Q, boost/cut and filter type (low shelf, band, high shelf) are adjustable.
MPX G2 User Guide Lexicon Crossover The Crossover effect is similar to Fc Splitter, but with only one crossover frequency, shared by low and high. In this effect, Level and Bal are not interpolated.
The Effects and Parameters PedalVol and ExtPedalVol Mix 0-100% Dry/Wet ratio Level* 0ff, -89dB to +6dB Amount of effect in processsed signal PedalVol is the same as Volume (S), except the Vol parameter is hardwired to the Foot Pedal input on the MPX G2. When using the MPX R1 MIDI Remote Controller, this parameter is automatically connected to the R1’s built-in pedal. This means that no patching is required to create a volume pedal effect.
