TECH drum machine based on a 8-BIT M50734 SP which manages 8 voices polyphony.
each voice can play a PCM SAMPLE with minor parameters edit (at 15 quantised levels):
- volume gain
- stereo panning
EDIT INTERFACE R100 is quite easy to use with logic matrix control interface:
WAVETABLE the R100 is a rompler machine which ROM contains 24 PCM samples at 32 kHz 12 bits. R100 PCM LIST: kick x3, ride x2, claps, timbale, snare x3, crash x2, shaler, claves, tom x2, cowbell, agogo, hihat x2, china and tambourine.
HEAR all the R100 sounds.
TECH: Officially there were 2 other EPROM kits sold by Kawai and a mod to switch between the kits.
SEQUENCER note entry system works in 2 possible modes:
- real-time quantisize range from 1/4 to 1/96 resolution
- step entries.
Some handy sequencer functions: erase, punch, reframe, swing (3 X modes, 12 X amounts), copy, overdub and insert.
SYNC tempo can be entered by TAP button, changed during a song or synched to external devices in different ways:
- Midi clock
- sync at 24 PPQ resolution
- tape sync protocol
- external analog trigger (24/48/96 PPQ)
The TIME ADJUST function sets the time offset if needed.
MIDI the machine receives and send Note with velocity, program change (pattern) and pads can be assigned to specific MIDI notes (for OUT) - in addition R100 handles Midi sysex.
- 100 patterns
- 100 songs
- 10 chains
- 3500 notes
Patterns can be saved to midi Sysex dump or to RAM cartridge model Kawai RC-16
MODIFICATION cheap digital drum machines are often modded for experimental noises. Most common modifications from the web are:
- EPROMS burning: wavetable is on 4 common EPROMS that can be reprogrammed with custom sounds
- Circuit Bending: experimental noises can be made bending both wavetable and R100 DAC.

Kawai R50 smaller version, no sensitive pads, less outs albeit it it features some extra effects. VIDEO
The R50 exists in 3 different ROM versions:
- R50 standard
- R50 E
- R50 III
