Untitled Document The MPX 1 Multi-Effects Processor fulfills the promise implied by the term "multi-effects." When summoned to do their best reverb, most single DSP multieffect processors run out of gas — you don’t get additional effects. The MPX 1 has Lexicon's own proprietary Lexichip, dedicated to delivering uncompromised Lexicon stereo reverb or ambience, in addition to another processor to create the other digital effects. So you get your best reverb, at all times, along with as many as 4 additional stereo effects.

Uncompromised Effects The MPX 1 employs two separate DSP processors: our proprietary Lexichip, dedicated to delivering world-class stereo reverb and ambience algorithms, and a separate, fast-math DSP processor to create the other effects. This means that uncompromised Lexicon stereo reverberation and ambience effects are available all the time, whether you’re running them alone, or in combination with any stereo pitch, chorus, EQ, delay or modulation effect. Many "multi-effect" processors can’t match even this basic requirement. The MPX 1 not only meets this standard expectation, but has processing power left over to run still more effects.
Instant Access The six effect types in the MPX 1 are accessible at all times via dedicated, back-lit buttons on the front panel. Each effect "block" is totally independent, with its own mix, level and bypass controls. The audio path through each effect is in stereo. An arsenal of exciting effects for each block (56 in total) is only a button push away, allowing you to easily select a new effect for any program.
Goof-Proof Program Fine-Tuning The MPX 1 comes loaded with 200 carefully crafted presets that really show off the the MPX 1’s versatility. Fine-tuning any preset to match it to your music or sound track is quick and easy with pushbutton access to a "soft row" designed to hold the most useful parameter combinations for each individual program. When you want to completely restructure a program, or create a new one from scratch, an Edit mode lets you dive as deeply as you want into an extensive pool of effect and program parameters.
On-Board Help A multi-level Help system built into the MPX 1 provides guidance through any front panel operation. At any time, simply press and hold any button to display a message explaining the function of the button without executing any action. This feature lets you look around and figure out most functions without ever having to open the user’s manual. In addition to press and hold Help, the MPX 1 has an optional Sleep mode help function which you can turn on for automatic display of useful messages when the system is idle.
Interactive Front Panel The MPX 1 front panel speaks for itself —with dedicated indicators and displays to let you know where you are and what features are available at all times:
Effect Select buttons light to show which effects are active in the current program
A Tempo LED flashes at the current tempo in any program that utilizes tempo- controlled delay times or modulation rates. A Tap button lets you change tempo on-the-fly
When the A/B LED lights, the A/B button lets you morph between effect or parameter variations.
A numeric display makes program and patch numbers highly visible
An alphanumeric display shows program, parameter and routing values
Dedicated Mix and Patch buttons give you instant access to mix and level settings of any or all effects, and the MPX 1 patch system. The Patch button lights whenever a patched parameter is displayed; simply press it to access the patch directly
Bypass lets you toggle master bypass
The Options button lights whenever additional functions and features are available.
Having many programs on-board is great, but with a library this large, how do you quickly find what you need? In the MPX 1, a built-in DataBase function makes it easy to find the right program for the moment. This database is completely user-definable, so you can reorganize all 250 programs any way you want. The MPX 1 DataBase Sort, Search and Show options include:
Sort by name
Sort by number
Search for source type (acoustic, drums, guitar, keyboard, live PA, sound FX, tempo and vocal)
Search for effect type (pitch, chorus, EQ, modulation, delay, ambient, chamber, gate, hall, inverse, plate and dual)
Search for source & effect (any combination of source or effect can be selected)
Show members of MIDI maps (Three 128-program maps are available)
Show members of program chains (10-program chains are available)
Last 10 programs loaded
Options When You Need Them The MPX 1 gives you as much control as you’re ever likely to want, while keeping the details out of your way until you need them. The Options feature is a good example of this. An Options button lights whenever there are additional features associated with the current display. Press Options to access the optional features. For example, when programs are displayed, press Options to access the DataBase Sort, Search and Show functions.
Additional options include:
Time Options: All MPX 1 delay parameters have an option which allows any delay time to be displayed in milliseconds, as echoes per beat, or in feet or meters
Rate Options: All MPX 1 rate parameters have an option which allows rate to be displayed in Hertz (Hz) or cycles per beat
Feedback Options: Feedback parameters have an option which allows any combination of effect blocks to be inserted inside delay or echo feedback loops
Patch Options: These options allow you to automatically "learn" MIDI control sources and create different control curves
Patching System The ability to dynamically control effect parameters is an essential aspect of creating great sounding, useful programs. Aside from the rate and envelope controls built into certain effects, the MPX 1 patch system provides more than 150 controllers that can be assigned to any effect parameter (up to 5 per program). These controllers include: LFO (2), ADR (2), Envelope Follower (2), Arpeggiator, Random Generator, A/B Glide, Tempo and Sample and Hold Generator.
Comprehensive MIDI Implementation In addition to the requisite bulk data dump and load functions, the MPX 1 provides an extensive set of MIDI control and processing features. In addition to global MIDI control for both individual and master bypass, mix and level, the MPX 1 gives you MIDI control of A/B and Tap, as well as all effect parameters. Tempo parameters synchronize to incoming MIDI clock, or the MPX 1 can transmit its own MIDI clock based on front panel Tap tempo. All MPX 1 internal control sources (audio levels, LFO’s, ADR’s, S/H, pedal, etc.) can be transmitted as MIDI Continuous Controller messages. A built-in arpeggiator "plays" MIDI sound generators and produces synchronized audio effects. In addition to separate OUT and THRU connectors, the MPX 1 supports remote power with a 7-pin DIN connector.
Audio Connections The MPX 1 is ready to plug and play in any situation: in a stage rig for guitar or keyboard, in a PA rack, in the studio or plugged into a digital workstation.
Operating levels from -10dB to +4dB
Analog I/O has balanced XLR and TRS 1/4" connectors
S/PDIF digital I/O
Great Expectations The MPX 1 is designed to exceed your expectations. With a well-balanced mix of high- quality audio effects, interactive control and intuitive operation, it has the sound, the flexibility and the feature depth to take you as far as you want to go quickly and creatively. The menus shown below give you a hint of what’s in store for you behind the front panel..
The Effects The MPX 1 has 56 pitch, chorus, EQ, modulation, delay and reverb effects, each with the audio quality and control flexibility you’d expect in a dedicated processor. A few examples are:
Multi-voice stereo chorus, flangers, phaser, wah, autopanner and much more Multiple Processor FX technology lets you combine these stunning effects into countless combinations.
Lexicon Reverberation Algorithms Lexicon's renowned reverberation algorithms are the sonic foundation of the MPX 1, and we give you a full spectrum: Ambience, Chamber, Hall, Plate, Gate — all are true stereo with independent processing of left and right inputs. The MPX 1's dedicated reverb processor ensures that you can load any reverb into any program, regardless of what other effects are already running.
The MPX 1 is the first effects processor to offer the Lexicon Ambience effect, previously available only in our dedicated reverberation processors (PCM 90, MPX 1 and 480L). Ambience is a "dry reverb" that can simulate the initial reflections of small through large rooms without the long decay associated with reverberation — an extremely useful effect for vocal and instrument sources and an essential tool for matching dialog or other source tracks.
Effect Ordering & Routing Maps The MPX 1 provides extremely flexible effect ordering and routing within each program. Ordering and routing of the six effect blocks is completely independent in each program. Effects can be placed in any order, simply by "dragging and dropping" them on a simple visual map.
Similarly, a routing map allows you to distribute the six effect blocks across two parallel stereo paths which can be split and merged at multiple points. The routing map is rewired by changing graphic "patch cord" connections.
Program Library The MPX 1 provides a large library of programs, crafted to provide a versatile array of sounds designed for a wide variety of performance, sound design and production applications. These programs not only exploit the unique characteristics of each effect, but provide useful examples of the effect combinations that can be created with the MPX 1. In addition, we’ve left space for 50 programs of your own design.
