TECH main CPU based on a NEC V25 (uP D70325L) manages 32 voices (or digital oscillators) polyphony - relative DAC is a 16 bits Burr-Brown PCM55HP.
A patch is composed by 1 or 2 PCM (single OSC /double 2 OSC) samples with individual settings:
||- volume mix
- delay start
- pitch detune (in double mode)
- interval at +/- 1 OCT. (in double mode)
PCM WAVETABLE Rompler module, internal ROM contains 256 PCM samples recorded at 16 bits resolution. The 03RW wavetable is roughly organized into 4 sound familes:
||- 138 acoustic samples
95 drum / percussion shots
- 12 DWGS (from classic hybrid synth Korg DW-8000)
- 10 digital samples from analog basic waveforms (e.g: sawtooth, square).
EXPANSION Wavetable can be expanded using special PCM cards (PIC from ebay auctions)
PERFORMANCE the COMBINATION mode handles up to 8 parts (16 in GM mode) each with individual functions:
|- Midi Channel assignment
- semitone transpose
- stereo panning
- volume mix gain
- keyboard zone
- 8 preset velocity curves
- 5 standard tuning scales
- aftertouch is assignable to: pitch, filter cutoff, amplitude or filter LFO amount
- external bender / modulation wheel can be assigned to OSC1/2 pan, filter cutoff (sweep) and modulation to pitch (both OSC1/2) or filter.

ENVELOPE up to 4 EGS with same 4 segments + 3 times + keytracking structure:
||- 1 EG amplitude (VDA) for osc1
- 1 EG amplitude (VDA) for osc2
- 1 EG filter (VDF) for osc1
- 1 EG filter (VDF) for osc2
Also 1 EG pitch: 3 segments + 3 times.
LFO up to 3 delayed modulators (the MG) sharing same shapes (triangle, up-sawtooth, down-sawtooh, square and random).
||- LFO VDF: can be applied to OSC1/OSC2/BOTH with variable intensity
pitch OSC1: with variable intensity, fade IN and retrig at note
pitch OSC2: same as LFO pitch OSC1.
FILTER simple non-resonant digital lowpass filter (VDF) with no special control.
TIP: The VDF can be controlled by aftertouch signal or assigned to modulation LFO (the "MG")

EFFECTS up to 2 processors can be chained in serial or 3 parallel modes.
Inlcuded effects are: reverb (hall, plate, spring ...) delay, chorus, flanger, distortion, overdrive, phaser, autopanning, rotary leslie, EQ and effects combination (e.g:
delay+rotary) HEAR FX flanger
MIDI full sysex control, a few Midi Control Change for basic controls.
Sounds and library can be saved to standard Midi dump.
- 128 ROM presets
- 100 RAM slots
- 100 COMBINATIONS
RAM can be doubled using memory card model Korg SRC-512 also used by other Korg synthesizer including famous mono V.A Prophecy synth.
Battery replacement: just open the rack, replace the CR-2016 (3V) into dedicated holder - click LEFT to magnify -
MAINTENANCE & MODDING module 03rw is very reliable, never had any troubles: maybe tact switches can be replaced after some time.
- No special modding but a CIRCUIT BENDING
