VOICES cpu NEC-V50 (part of 70216 family) manages 16 voices polyphony based on 16 bit AI System subtractive synthesis - M1 DAC is a Burr Brown PCM 54HP.
basic patch is composed by 1 or 2 PCM (single/double) samples with individual settings:
- pitch detune
WAVETABLE 4 Mb ROM contains 149 waveforms organized in 3 categories:
- 75 PCM acoustic: acoustic instruments including strings, violins, sax and piano
- 44 PCM drum: percussions and chromatic
- 30 PCM DWGS: pre-calculated mathematically generated waves like additive harmonic, vocal formants and traditional basic waves like sine, saw or pulse.
TECH: DWGS were originally developed on previous model Korg DW8000.
EX UPGRADE standard wavetable can be expanded to EX with further 4 Mb PCM, in this case the rackmount became M1EX (EX upgrade is factory native in successive T series).
Even more waveforms can be added using Korg M1 PCM cards or others AI2 compatible Korg systems like Korg M3r orWavestation. Here's the list of the official cards, but there are plenty more from third-part :

PERFORMANCE the COMBI mode manages up to 8 parts at the same time with individual parameter settings:
- aftertouch assignable to Cutoff / EG AMP / LFO pitch/ or LFO filter
- volume mix
- zone split
- velocity split
- damper on filter
- scales one microtonal user-free slot + 4 ROM presets:
equal temp 1-2 pure major-minor.
FILTER section is the VDF Variable Digital Filter is a non-resonant lowpass filter with Keytrack function.
ENVELOPE up to 6 EGs:
- VDA amplitude : OSC1 and OSC2 4 segments + 2 times
- VDF filter: OSC1 and OSC2 4 segments + 4 times
- Pitch EG: :OSC1 and OSC2 4 segments + 2 times.
LFO there are 2 delayed and syncable modulators called MG (shapes: triangle, saw up, saw down and square)
MG1: modulates OSC1-OSC2 pitch
MG2: modulates filter VDF.
EFFECT DSP manages double 16-bits sound processors combined in parallel or serial mode.
There are mainly 9 categories effects: reverb, delay, overdrive, equalizer, chorus, leslie, phase shifter, frequency exciter and flanger.
SEQUENCER works in both real-time or step notes mode (quantizing up to 1/48 resolution) and manages 8 tracks.
MIDI limited CC# implementation but the exclusive systems are complete.
TIP: the MINDSCOPE function is a neat too for incoming events monitoring.
RAM: 100 patches
RAM: 100 combi
RAM: 10 songs + 100 patterns 4400 notes (7700 reducing memory balancing between patch- combi).
Sounds can be saved using special MCR03card.
Battery replacement: internal battery is a 3V lithium CR-2032 with holder, it is quite common and easy to replace.
