SOUND system based on a Intel P8098 CPU which handles 30 voices polyphonic subtractive synthesis RS PCM Resynthesized Pulse Code Modulation. RS concept resynthesizes and rebuilds new harmonics using a custom sample interpolation, but it lacks a filter structure, in fact RS can be mistaken with older L.A synthesis implemented in Roland D-50 model.  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. The upper level is the timbre composed by a single tone that has some editable parameters: volume, detune and vibrato LFO.  Finally 6 timbres make a patch for performance. 

WAVETABLE 4 Pure rompler synth: 3MB ROM (6X 512 kb ROM) is organized in 2 sound groups:
- acoustic samples eg: piano, bell, guitar, string, organ, brass [...]  - precalculated basic waveforms eg: pulse, sawtooth and generated harmonics.

CARD EXPANSION The ROM can be expanded using special PCM cards, also compatible with: Here's the list of available models: SN-U110-01: Pipe Organs & Harpsichords SN-U110-02 :Latin and FX Percussion SN-U110-03:Ethnic SN-U110-04: Electric Grand and Clavi SN-U110-05: Orchestral Strings SN-U110-06: Orchestral Winds SN-U110-07: Electric Guitar SN-U110-08: Synthesizer SN-U110-09: Guitar and Keyboards SN-U110-10: Rock Drums INFO SN-U110-11: Sound Effects SN-U110-12: Sax & Trombone SN-U110-13: Super Strings SN-U110-14: Super Ac Guitar SN-U110-15: Super Brass >Also third part cards from Musitronics Akkordeon (ID: 25 / Analog Synthesizer / Voices (ID: 22) / Eldek (ID: 21)

U220 Parameters

ENVELOPE a single 4-stages amplitude EG.

LFO  modulates only the amplitude with variable depth, delay time and 9 shapes: triangle, sinewave, 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.

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. 

MEMORY 64 patches + 64 performances  + 4 rhythm sets. MEMORY  is doubled if RAM card model Roland m-256 is fitted.
