info SOUND MODULE The main panel features a 16 X 2 lines backlit display, 25 buttons, a slider edit for data entry and a vector joystick for volume mix.

Back panel terminal connectors:
- Midi Interface
- main out
- headphones out.


acPower supply is external with 12V DC / 500mA - any general PSU AC/DC 9/12V can work with correct polarity -)+

 



edit TECH a 8-bits cpu NEC D78310G manages up to 16 oscillators or voices relative DAC is a uPD-6355G.

STRUCTURE Each K1M voice is composed by a maxium of 4 assigned waves or SOURCES.
K1 ROM contains 256 waves at 8-bits resolution organized in 2 families:
- VM cyclic waveforms: 204 waves
- PCM acoustics: 52 waves sampled from true percussions & drums.

wavetable
VM SYNTHESIS cyclic waves have been pre-generated by additive synthesis process out of 128 harmonics groups.
The VM is 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

signal flow

 

adsr PERFORMANCE machine manages up to 8 parts with individual parameters:
- keyboard zone assign
- voices reserve (priority)
- mix gain level
- Midi channel assign
- semitone transpose
- pitch tune.

adsr ENVELOPE
a 4-segments + 1 time EG DADSR for each source.
The vector joystick controls a global mix amplitude EG moving between 4 oscillators but it cannot be recorded. There are 18 preset velocities curves and no possible edit.

decay




lfo LFO
a single oscillator (4 shape: triangle, saw, square and random) modulates 2 main destinations:
- LFO to pitch
- LFO to amplitude.
