edit VOICE system based on a Intel P8098 CPU which handles up to 30 voices polyphonic subtractive synthesis RS PCM Resynthesized Pulse Code Modulation.
RS SYNTHESIS the RS concept resynthesizes and rebuilds new harmonics using a custom sample interpolation, but it badly lacks a filter structure. The RS could be mistaken with older L.A synthesis implemented in the later Roland D-50 model, but the reality is that RS is more like a plain rompler than a true synthesis system.

edit EDIT sound hierarchy is a bit confusing: the lowest level is a tone which is composed by either 1 or 2 samples (2 samples tone reduces the whole polyphony) out of 128 tones available (drum is apart) with no possible edit.
STRUCTURE the upper level is the timbre composed by a single tone that has some editable parameters including:
- volume
- detune
- vibrato (LFO)
Finally 6 timbres make a patch for final performace.


edit timbre


edit WAVETABLE the 3MB PCM ROM (6X 512 kb ROM) is organized in 2 sound groups:
- acoustic samples eg: piano, bell, guitar, string, organ, brass ...
- precalculated basic waveforms e.g: pulse, saw and generated harmonics.



edit PERFORMANCE module manages up to 6 timbres (+ 1 drum part) and individual settings:
- split zones
- stereo panning position
- volume
- voice priority
- analog out routing
- voice reserve : sets a number of voice for each part for priority
The incoming aftertouch can be assigned either to LFO, pitch and volume.

edit ENVELOPE a simple 4-stages amplitude EG.



edit LFO modulates only the amplitude with variable depth, delay time and 9 shapes: triangle, sin, square, saw up, saw down, trill (x2) and random (x2).
Special AUTOBEND function is a basic modulation for a pitch-warp effect, so it should be considered as another simpler LFO.

vibrato LFo


edit EFFECTS there are 2 main FX sections with limited edit parameters:
- reverb: 9 presets including hall, delay, room and gate
- chorus: 5 presets including chorus, flanger and delay.




edit MEMORY:
- 128 tones
- 64 patches
- 64 performances
- 4 rhythm sets
RAM is doubled if RAM card model m-256 is present.
Battery replacement: a simple 3V CR-2032 in holder.
