Multi-Effects Processor (1988)
OVERVIEW LXP1 offers 16 preset reverb patterns, 128 user memories accessible by MIDI controller, some adjustable parameters thanks to optional remote programmer/controller MRC (pic below). Quite easy to use with a 16-position rotary encoder to select the effect. Two more knobs labelled Decay and Delay, these provide editing control over main edit e.g with reverb programs these are reverberation decay time and pre-reverb delay (up to 0.25 seconds in all cases). In other programs you have to check out the manual for relative parameter.
GROUPS There are two main groups to choose from: effects and reverb. Reverb have various sub-section like: HALL (dark bright), ROOM (small medium large) and PLATES (also dark bright). Other effects are chorus, gated reverbs and delay (with various panning ping pong effects)

For avanced editing the MRC is needed, as, for exemple the reverb have many possibile tweaks: Decay Time, Pre-Delay Time, Pre-Delay Feedback, Size, Diffusion, Bass Multiply, High-Frequency Cutoff and Effects Level. The Mrc (version 4) is compatible with other Lexicon FX units as the famous PCM-70, and LXP-5.
The factory programs are dedicated to those machine, but the MRC is able also to control generic machines units (e.g CC, pitchbend) but also SYSEX strings to edit older machines or even synthesizers. You can save your custom setups in one of the 20 slots available.
