VOICE core CPU Risc-32 manage 32 voices polyphony based on DAS - DSP ADVANCED SYNTHESIS (3x ASP Panasonic MN19412A) relative DACs are a Burr-Brown PCM69AU.
A basic k5000 patch is composed by 6 digital oscillators or so-called "elements" and each DAS element can be either a:
PCM sample wave
DSP additive wave (2)
ADDITIVE ELEMENT k5000s DSP generates 128 sinewave harmonic that can be summed following the traditional Fourier principle. The whole sinewaves are split into 2 harmonic groups (each group counts for 1 element):
- first harmonic group: from 1 to 64
- second harmonic group: from 64 to 128.
The relative harmonics levels can be set in 4 ways:
DHL: step by step values entries
- DHE: EG envelope
6 macro harmonic templates: bright, odd, even, octave, 5th and whole-harmonics selection.
- Morphing function which is able to record up to 4 harmonics snapshots with progressive interpolation values for a smooth motion.
PCM ELEMENT internal 16 bits ROM contains 123 PCM waveforms split into 2 main category groups:
PCM acoustic instruments
- PCM transient attack PCM.
PERFORMANCE special MULTIMODE manages 4 parts with individual features:
- mix gain
- panning position
- zone assign
- transpose and tune
- Midi assign.
ENVELOPE 5 EGs:
- amplitude osc: 4 segments+ 2 levels
- pitch osc: 4 segments+ 2 levels
- standard filter: 4 segments+ 2 levels
- formant filter: variable structure.
- harmonic: variable structure every harmonics has its own EG with possible loops scan between decay segments.
FILTER the special filter DCF is multimode:
highpass (for both PCM+ ADD)
lowpass (for both PCM+ ADD)
formant (only ADD) is a 128 bands resonant comb-model defined by 128 DFL steps, each step contains 2 values for both level and envelope. For quick edit it is possible to fill steps using the macro bands selections (5-10-15-20 or whole ALL).
LFO 4 digital modulators (shapes: triangle, saw, random and square) and 4 destinations:
- LFO to oscillator pitch
- LFO to
LFO to filter "standard"
LFO to filter formant.
EFFECTS fully editable sections includes: reverb, delay, chorus, flanger, leslie, distortion, exciter and overdrive.
MIDI quite all parameters can be controlled by Midi Control Change and K5000S outputs the frontal knobs as standard CC# values.
ARPEGGIATOR really complete with adjustable octave range, hold, random notes, gate velocity. The arpeggios are midi-output to other devices and they can be synched to external Midi clock tempo.
IMPORT function loads short Midi files into special slots for creative arpeggios edit.
REPAIR & MAINTENANCE no great issues there, with time it might be necessary to replace:
- tact switches
electro-luminescent EL display backlight
256 RAM patches.
RAM doubled if special memory expansion model Kawai ME-1 is fitted.
Sounds and performances can be saved either to Midi Sysex dump or to internal 1,44 MB disk drive
which file system is a standard PC MS-Dos file system.
