waveforms

info RACKMOUNT single unit. Main panel features a simple 16 x 2 lines LCD and 20 buttons.
Back panel terminal connectors:
- Midi interface
- main out

- headphonses
- data card slot.

acPower supply is external with 12V DC 500mA.

 


edit TECH a 8-bits cpu NEC D78310G manages up to 16 oscillators or polyphony 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 PERFORMANCEmodule manages up to 8 parts with individual parameters:
- keyboard zone assign
- voices reserve (priority)
- mix gain level
- Midi channel assign
- semitone transpose
- pitch tune.



k1r




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.
There are 18 preset velocities curves and no possible edit.
VECTOR since the K1r lacks the vector joystick, there are some free sotware that emulates the stick using exclusive systems.


vector control

 


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