SOUND modules based
on a 16 bits NEC V50
(μPD70216) CPU manages 32 voices
polyphony based on Korg AI2 synthesis with a DAC Burr
A basic patch is composed 1 or 2 samples (oscillators)
that can be set in 2 manners:
- single: 1 oscillator per sound
- double: 2 oscillators per sound.
Just a few oscillator parameters can be edited
including: volume, tuning, panning and delay startwave.
internal 6 MB ROM contains 255 PCM
coded at 32 kHz wavetable including 3 kinds of samples
- acoustic instruments
- FM sampled
- mathematically generated.
waves can be added using special PCM cards also
compatible with 03RW.
list is NOT complete, cards picture from ebay
auction we do not have them yet.

digital process changes the harmonics contents
of a sample distorting it with 59 cycled
waveforms each with specific spectral
harmonics. Waveshapes are not really editable except for
the shaping envelope + amount applied to the sample.
AUDIO EXAMPLE MP3 demo
the wave sinewave starts with no waveshaper then
processed with same EG through the 59 waveshapers one
after one. Below how the waves changes.
TECH :Years later waveshaping had been
re-implemented on korg synthesizers including: Z1- Prophecy - Microkorg XL
manages 8 combination parts and some individual
- Midi channel
- pitch detune
- volume / pan
- split zone
- analog out assign.
LFO 3 digital
- LFO MG1 modulates oscillator 1
- LFO MG2 modulates oscillator 2
- LFO MG3 modulates filter VDF cutoff (the MG VDF can be
activated individually to OSC1 or OSC2).
Some extra LFO functions like delay start, note retrig,
modulation by aftertouch and ajustable depth.
5 possible waveforms: triangle, saw-up, saw-down, square
ENVELOPE 5 digital
- EG VDA 1 amplitude for oscillator 1: 4 segments EG + 3
- EG VDA 2 amplitude for oscillator 2: 4 segments EG + 3
- EG VDF filter: 4 segments EG + 3 time
- EG pitch: 3 segments model + 3 times.
FILTER the VDF is
a digital 2-poles lowpass filter, the emphasis Q

engine processors at 16 bits in serial or parallel mode.
This section offers 47 different effects such as reverb,
delay, overdrive, EQ, chorus, rotary speaker and some
combo of them.
tracks recordable by real time or step by step mode.
Recording system handles various handy functions such
as: OVERWITE, PUNCH IN, LOOP, OVERDUB, TRANSPOSE, FILTER
EVENT, BOUNCE, COPY TRACK, VELOCITY MODIFY.
SYNC sequencer can be set to external
or internal Midi clock in master or slave mode.
computer-based editors for 01w and 01RW:
- Midiquest (PC/MAC, commercial)
- Soundtower 01wEditPro (PC, commercial)
- Atari EMC editor (atari ST)
2 common issues:
-after some years the screen may disappear as
well as sound generation. Some bad capacitors
leak inside creating corrosion around tracks,
some luck there is no custom KORG IC around, I
had to replace these: C85, C29 and C30, C102,
C103 and C130.
It seems that NOT all series suffer from this
- display backlight: LCD fades out you have to
replace the E-foil. Quite easy to do requiring
some basic soldering skills.
right picture: bad capacitors alert!
