TECH main core 8-bits HD 63B03X manages 8 voices polyphony based on DWGS Digital Waveform Generator System subtractive synthesis. Each voice is composed by 2 oscillators DCO + 1 white noise circuit with variable parameters:
|
-
volume gain
- octave set 16' / 8' / 4'
- pitch detune |
WAVETABLE the 256 kb ROM (4X EPROMS) contains 16 short-cycled spectral 8-bits PCM TECH: It seems to be possible to hack the internal EPROMS to change the waves.
|
waveform list : sawtooth, square, piano, electric piano (x2), clavinet, organ, brass, sax, violin, guitar, electric guitar, bass, digital bass, bell and whistle. |
PERFORMANCE the system handles voices in various playmodes:
- poly1 rotate sequentially the 8 voices in constant order
- poly2 same as poly1 but restarts from first voice
- unison1 retriggers the EG when a key is pressed
- unison2 only the first key activates the EG
- aftertouch be assigned to filter, amplitude or LFO depth
- joystick can be assigned to pitch, LFO and VCF cutoff
- interval transposes the OSC2 pitch to keep a constant interval above first OSC values: minor 3rd, major 3rd, perfect 4th, perfect 5th and unison. |

FILTER based on analog 8 X NJM2069 (same found on Korg Poly-800 which is paraphonic)
Lowpass resonant VCF at -24 dB/Oct and polarity inversion. Section features a primitive Keytrack system and 4 fixed rates: 0 / 25 / 50 / 100 %.
|
Hear cutoff and resonance |
LFO a single delayed modulator MG (shapes: triangle, square saw-up and saw-down) and 2 destinations:
|
- OSC 1 & 2 pitches (both not individual)
- VCF cutoff.
Hear LFO |
ENVELOPE 3 EGs:
|
- EG1
VCA: 4 segments + 2 times (ADBSSR)
-
EG2
VCF: 4 segments + 2 times with polarity inversion
- autoBend: simple pitch EG (OSC1 / OSC2 or both) 2 modes up / down. |
EFFECT 12 bits digital delay with 2 - 512 ms time range able to generate short delays and chorus. Time can be set in coarse of fine mode as well as total feedback.
Hear delay
MEMORY:
- 64
slots in RAM patches.
Sounds library can be saved to either Midi sysex dump or magnetic tape.

LEFT - System works with a 3V CR-2032 soldered to the mainboard, you have to disassemblethe whole keyboard and remove board KLM-661-3.

EDITORS there are some free and commercial editors for DW8000:
- Soundquest (MAC/PC $$)
- ctrlr (PC LINUX)
- DW8000 Patch Editor (old PC OS free)
UPGRADE third-part companies projected some hardware boards that adds some new functions like split, key transpose, random LFO and more. |
