The Kawai K1
Digital Synthesizer (1988)
Cult lo-fidelity synthesizer based on 8-bits short-cycled waveforms.
A must for noisy textures and raw sounds. Sadly the K1 misses filter structure, later implemented on revamp model k4.
KEYBOARD 61 keys with velocity and aftertouch.
Main panel features a 16 x 2 lines LCD display (now some modern OLDED replacements are available), 26 buttons, a data slider, a vector joystick and 2 wheels for pitch bending and modulation.
Back panel terminal connectors:
main signal out
footswitch pedal input.
Power supply is external with 12V DC, any general PSU AC/DC 9/12V is ok with correct polarity -)+ and amp rate.
TECH a 8-bits cpu NEC D78310G manages up to 16 oscillators or voices polyphony- relative DAC is a uPD-6355G.
Each K1 voice is composed by a maxium of 4 assigned waves or SOURCES.
WAVETABLE ROM contains 256 waves at 8-bits resolution organized in 2 families:
- PCM acoustics: 52 waves sampled from true percussions & drums.
- VM cyclic waveforms 204 waves: generated by additive synthesis process out of 128 harmonics
composed by 2 sub-categories:
* BASIC classic basic waveforms e.g square, saw and sine.
* FREQUENCY RANGE are spectral transients e.g piano, strings, brass, lead, bell and organ.

PERFORMANCE machine manages up to 8 parts with individual parameters:
- keyboard zone assign
- voices reserve (priority)
- mix gain level
- Midi channel assign
- semitone transpose
ENVELOPE a 4-segments + 1 time EG DADSR for each source.
There are 18 preset velocities curves but no possible edit.
Vector joystick controls a global mix amplitude EG moving between 4 oscillators.
LFO a single oscillator (4 shapes: triangle, saw, square and random) modulates 2 destinations:
LFO to pitch
LFO to amplitude.

MIDI standard implementation with just a few CC# but full compliant to Midi Exclusives data for both edit and backup.
MEMORY (RAM chip is a NEC D4464C9):
64 RAM standard patches
32 RAM multitimbral
RAM is doubled with memory card model DC8, also compatible with DC16 and DC32.
Battery replacement: soldered lithium battery 3V Cr-2032
