Sound & Performance

SOUND the rack main core is a single 8 bits NEC model D70320 which manages up to 16 voices polyphony; DAC is a Burr Brown PCM54HP.
A patch is composed by 1 sample PCM at 16 bits resolution based on "AI SYNTHESIS" with some edit parameters:  octave range: 4' / '8' / 16', volume gain setting, stereo panning , delay start and  monophonic mode.
Internal 3 MB ROM is organized in 3 wave categories: 45 PCM: percussives + 80 PCM acoustic instruments + 9 DWGS mathematically pre-calculated PCM derived from classic hybrid analog-digital Korg DW-8000. Rom can be expanded with several cards (list on new chapter), M3R wavetable can be expanded using some cards usually set of PCM+DATA: HINT: M3R and M1/m1r PCM cards are compatible, but not the DATA ones.

PERFORMANCE the combination mode up to 8 parts with settings:
Midi channel assign , keyboard zone assignment ,semitone transpose, volume-panning, pitch tuning , damp amount. External keyboard aftertouch can be routed to pitch, LFO1-2, filter or amplitude.

Filter, Envelope and LFO

FILTER VDF is digital, a simple non-resonant low-pass model.

LFO Up to 2 delayed modulators MG (4 shapes: triangle, saw-up, saw-down and square) with variable depth and retrigger option mode:  LFO 1 to pitch  /  LFO 2 to filter.

ENVELOPE 3 digital EGs:
- EG OSC VDA: 4 segments + 3 times  
- EG OSC VDF: 4 segments + 4 times  
- EG OSC pitch EG: 3 segments + 3 times

Memory and effects

EFFECTS  double digital engines that can be chained in either serial or parallel mode : equalizer, reverb (x9) delay (x2), chorus (x2), flanger (x2), tremolo (x2), phaser (x2), frequency exciter and ovedrive.

MEMORY:  100 programs +  100 combinations,  RAM doubled when using custom MCR-03 memory ards. 
Battery Replacement : a
 simple CR2032 in a simple holder: just open the rack, locate the holder then replace it with a fresh one. Then you have to reload your sounds: the factory patch set can be recalled anytime just follow this simple keystroke procedure: EDIT, GLOBAL, go to page 5, RELOAD PRESET, OK
