Kawai’s XD-5 is documented in its own manual and was firmly in the period music press by May 1991. It arrived as a 16-bit digital percussion synthesizer: a drum source whose samples, digital waveforms, filters, envelopes and routings could be built into an individual voice rather than selected as a finished kit.
A drum module for people who wanted to take things apart
The XD-5 looks like a compact 1U sound module, but Kawai designed it as a percussion synthesizer. Its manual describes a machine with 256 onboard waveforms, including 16-bit PCM and Digital Cyclic sources, plus digital filtering, amplitude modulation, ring modulation and 16-note polyphony. The point was not simply to call up a snare. It was to combine sources, decide how a hit behaved, and make a kit from there.
The review that caught the idea
Vic Lennard’s May 1991 Music Technology review makes the trade-off plain. The XD-5 left sequencing to the rest of a MIDI setup, then gave its owner room to layer up to four sources into a Tone, shape envelopes and velocity response, assemble 88-note kits, and route sounds through stereo and six individual outputs. Lennard thought the work paid off when a player knew which corner of a percussion sound they wanted to bring forward.
A Kawai pitch for stronger tracks
Kawai America’s 1991 campaign called the XD-5 a full percussion synthesizer rather than a sample-playback box. Its ten-point sales pitch concentrated on sound stacking, programmable 88-note kits, digital filters, output routings, pattern disks and a library of ROM kits. The language is commercial, but it is useful commercial history: Kawai was selling a drum module as an open-ended studio instrument, not a replacement for a sequencer.

Richie Hawtin’s spare non-Roland colour
Richie Hawtin told Sound On Sound that the Kawai supplied the non-Roland drum sounds in his Concept 1 sessions of 1996, the working year that led into Plastikman’s Consumed. It is a precise and revealing use case. In a setup remembered for 909s, 303s, Serge and long live takes, the XD-5 was the alternate texture: a small rack module contributing percussion that did not have to sound like the rest of the room.
