Getting Started Introduction Thank you for your purchase of the MPX 100 Dual Channel Processor. The MPX 100 is a true stereo dualchannel processor with 24-bit internal processing, 20-bit A/D-D/A and S/PDIF digital output. Powered by a new version of Lexicon’s proprietary Lexichip™, the MPX 100 has 240 presets with classic reverb programs such as Ambience, Plate, Chamber and Inverse, as well as Tremolo, Rotary, Chorus, Flange, Pitch, Detune, 5.7 second Delay and Echo.
Bypass Mutes or bypasses the signal depending on the setting of the System Bypass parameter. (Press for 2 seconds to access System Parameters.) Effects Lvl/Bal Sets the level of the Single effects and the balance of the Dual effects. Input Sets the level of the incoming signal. LEDs indicate acceptable signal level (green), or clipping (red). Edit LED Lights to indicate program is altered but not stored. Front Panel Overview Store Initiates store procedure. (When pressed with Tap, activates MIDI Learn.
Setting Audio Levels 1. Start with INPUT set to 9:00 o'clock and OUTPUT all the way down (fully counterclockwise). 2. Set the instrument output or effects send being input to the MPX 100 to a nominal level and play, or send audio to the MPX 100. The Level LEDs* should light green. If the Clip LEDs light red at this point, turn down the output of the instrument or effects send until the Clip LEDs remain off during the loudest passages. 3.
Rear Panel Connections MIDI Two 5-pin DIN MIDI connectors are provided for MIDI IN and software selectable MIDI OUT/THRU. POWER Use Lexicon 9VAC power pack. OUPUT Single-ended (unbalanced) stereo outputs provide +8dBu typical output level. Use the right output connector for mono output. If no connection is made at the right output, the left output can be used to drive headphones at modest volume. DIGITAL OUTPUT RCA S/PDIF connector. INPUT Single-ended (unbalanced) inputs accept levels as low as -30dBu.
Audio Connections Headphones Footswitch Audio connections to the MPX 100 are unbalanced and should be made with high quality shielded cables with 1/4" tip-sleeve phone plugs at the MPX 100 end. A stereo signal which is adequate to drive headphones is available at the left output (provided no connections are made through the right output). This feature is provided as a convenience for practice purposes, and is intended to provide only modest volume.
The MPX 100 can be used as two independent Effects Processors with Dual Program Variations 11-16. Designate two auxiliary sends on your console and connect one to the left MPX 100 input, and the other to the right input. Refer to the Program Descriptions to take advantage of this configuration.
Basic Operation Selecting Programs All of the programs on the MPX 100 are selected with the front panel PROGRAM and VARIATION knobs. The PROGRAM knob selects Single or Dual program banks. The VARIATION knob selects different program versions. The Single selections are arranged around the left side of the PROGRAM knob; the Dual selections and the User bank are arranged around the right side of the knob.
Dual Programs User Programs When User is selected with the PROGRAM knob, VARIATION selects 16 memory locations available for storing your own programs. When one of the Dual Programs is selected, the VARIATION knob will load 16 different programs, each containing two effects. (When shipped, User variations 1-16 contain duplicates of a selection of the factory-installed programs.
Editing Editing MPX 100 programs is easy. We've arranged the critical parameters of each program under the front panel Adjust knob, so all you have to do is turn the knob to adjust the program to suit you. You can also adjust the level of the Single programs, or the Effects Balance of the Dual programs with the Effects Lvl/Bal knob. Changes made with either knob are recognized as edits, and will cause the front panel Edit LED to light to alert you to the fact that the program has been altered.
Tap Tempo Functions Varying the Rhythm Audio Tap The MPX 100 Tap Tempo feature allows you to set the delay times and modulation rates of tempo-based programs to the beat of the music. To set the tempo from the front panel, simply press the Tap button twice in time with the music. That’s your tempo. No more dialing up what “could be” the delay time in milliseconds — just tap twice — the MPX 100 will figure out the time for you. When you want to change tempo, just tap twice again in the new rhythm.
Setting Tempo via MIDI When used in conjunction with the Learn feature, Tap can be set remotely from any MIDI device. MIDI controllers, such as Lexicon's MPX R1 Foot Controller, can be used to send Continuous Controller messages or Program Changes to the MPX 100 or you can send Continuous Controller or Program Change messages from the button and fader moves of many mixing consoles. The MPX 100 will Learn these messages and allow you to set tempo via MIDI.
Storing Programs When you want to save a program, press Store. The Store LED will flash slowly to indicate that the MPX 100 store function is armed. (If you want to exit without saving the current program, press Store again.) Turn the PROGRAM knob to User, then use VARIATION to select one of the 16 User locations. Press Store again to save your program to the selected location (and overwrite the program previously stored there). The Store LED will flash rapidly while the store operation is completed.
System Mode System parameters and MIDI dumps are activated in System mode. To enter this mode, press and hold Bypass for approximately 2 seconds. The Bypass and Store LEDs will blink slowly to indicate you are in System mode. The adjustable parameters available in this mode are shown in the chart on the following page. Turn the VARIATION knob to select a parameter. Press Store to toggle the state of the parameter, or to execute a MIDI dump. The Edit LED will show the current state of each parameter.

Program Descriptions The 240 programs in the MPX 100 are designed to provide a full palette of high caliber ambience, reverb, delay, pitch shift and other effects. As you audition the programs, be sure to vary the Adjust knob. The Adjust knob has been carefully customized for each individual program. In many cases it controls several effect parameters simultaneously to provide simple control of a complicated editing process.

Delay, Echo The MPX 100 Delay, Echo variations include mono (5.5 seconds), stereo (2.7 seconds) and 6-voice multitap effects. Each of the 16 variations can be used for digital delay or tape echo effects. When Adjust is turned past its center postion to the right, tape echo effects are produced. (Each repeat is darker and softer.) When Adjust is turned to the left of center, digital delay effects are produced. (Each repeat is the same timbre, but softer.

About the Dual Programs The MPX 100 Dual programs combine either a Delay or Reverb algorithm with a Flange, a Pitch or a Chorus. Effects Lvl/Bal controls the relative balance of each effect in the combination. Four routing configurations are used in the variations of each Dual program: Dual Stereo (Parallel), Cascade, Mono Split and Dual Mono.
Generally, the Effects Lvl/Bal knob controls the balance of the two effects in each dual program. In the cascade variations, rather than simply controlling balance, the knob varies the amount of the first effect or dry signal which is fed into the second effect.

MIDI Operation MPX 100 MIDI Behavior The MPX 100 “learns” MIDI Channel, Program Change and Continuous Controllers in its Learn Mode. As many as five Learn patches (for the front panel Mix, Effects Lvl/Bal, Adjust, Bypass and Tap controls) on as many as five MIDI Channels are supported. Program Change messages 0-15 are reserved for executing program loads on any learned MIDI Channel — or a separate MIDI Channel can be selected for program load.
Assigning a MIDI Channel for Program Load In order to use Program Change messages for Program loads as well as to control front panel buttons, the MPX 100 is designed to have one MIDI channel dedicated to loading programs. This is called the Program Load MIDI Channel. Although this channel can be used to receive other Program Change messages, numbers 0-15 will always load the 16 variations of the currently loaded program. Program Change messages 0-15 will be ignored on all other MIDI Channels.
Using Program Change Messages for Program Load The MPX 100 will allow loading of all of its 240 preset and 16 User programs via standard MIDI Program Change messages. It also conforms to the use of MIDI controller 32 to perform Bank Select, starting with the User bank as the first bank. (For the purposes of this discussion, each setting of the MPX 100 PROGRAM knob selects a “bank” of 16 programs.) The MPX 100 “banks” are ordered numerically from 0-15. Here’s how it works.
Learning Continuous Controllers The MPX 100 recognizes Pitch Bend, AfterTouch and MIDI Continuous Controllers 1-31 and 33-119. To Learn a Continuous Controller: 1. Simultaneously press Store and Tap to enter Learn Mode. (The Store LED flashes slowly and the Tap LED lights steadily to indicate Learn Mode is active.) 2. Move one of the MPX 100 front panel controls (Mix, Effects Lvl/Bal, Adjust, Bypass or Tap) to assign it to the controller. 3. Move the MIDI controller through its full range.
Activating Bypass or Tap functions with Program Change Messages The MPX 100 recognizes MIDI Program Changes 16-127 (17-128 on some MIDI devices) on any channel. To assign a Program Change message to Bypass or Tap: 1. Simultaneously press Store and Tap to enter Learn Mode. (The Store LED flashes slowly and the Tap LED lights steadily to indicate Learn Mode is active.) 2. Press the front panel button you want to control (Bypass or Tap). 3. Send a MIDI Program Change to the MPX 100.
Clearing a Learned Assignment 3. Press Store to clear the assignment. The Store LED will flash rapidly. Learnable Front Panel controls and Assignable MIDI Sources MIDI MIDI Front Panel Controllers Pgm Change Control 1-31, 33-119 16-127* 1. Simultaneously press Store and Tap to enter Learn Mode. (The Store LED flashes slowly and the Tap LED lights steadily to indicate Learn Mode is active.) 4. To clear another front panel assignment, repeat steps 2 and 3. 5. Simultaneously press Store and Tap to exit.
MIDI Clock MIDI Dumps The MPX 100 recognizes MIDI Clock messages and applies the tempo (40-400 BPM) to any program which utilizes the Tap-tempo feature. Connect a MIDI device which outputs MIDI Clock (such as the MPX R1 foot controller or a MIDI sequencer) to the MPX 100 MIDI IN jack, to have the MPX 100 automatically recognize and begin to process the MIDI clocks. When you change tempo on the connected device, the MPX 100 will follow along and adjust its delay times or rates to match the tempo.
