SOUND main core 8-bits at 2 mHz HD63b03X 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 between 16' / 8' / 4'
- pitch detune. |
DCO WAVETABLE the 256 kb ROM (4X EPROMS) contains 16 short-cycled spectral8-bits PCM. It seems to be possible to hack the internal EPROMS to change the waves.
|
DW800 internal 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 rotates sequentially 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
|
Some other performance functions:
- aftertouch be assigned to filter, amplitude or LFO depth
- joystick can be assigned to pitch, LFO frequency 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 OTA IC analog 8 X NJM- 2069AD9, same found on Korg Poly-800 which is paraphonic, a lowpass resonant VCF at -24 dB/Oct and polarity inversion.
|
VCF offers a primitive Keytrack system with 4 fixed rates: 0 / 25 / 50 / 100 % |
HEAR VCF cutoff resonance
LFO a single delayed modulator MG (shapes: triangle, square saw-up and saw-down) and 2 modulation destinations:
|
- LFO OSC 1 & 2 pitches (not individual)
- LFO TO VCF cutoff
|
HEAR LFO modulator to VCF
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 a 12 bits digital delay is onboard with 2 - 512 ms time range able to generate short delays and chorus; DW delay ime can be set in coarse or fine mode as well as total feedback amount.
HEAR delay panned
ARPEGGIATOR features 3 direction modes: up, down an special custom which records up to 64 notes - in addition It is possible to set the octave range and a latch mode.
|
SYNC arpeggiator temp cam be set internally or synched to external Midi clock.

Sounds library can be saved to Midi sysex dump or to magnetic tape.
Battery replacement: System works with a 3V CR-2032 soldered to the mainboard - click to enlarge pic |
OS ROM operating system can be displayed switching on the Dw8000 holding [1] + [2].
Lastest known version is officially 1.2
UPGRADE third-part companies like Musitronics Turbo "DW800EX angel" projected some hardware boards (MODS) that adds some new functions like split, key transpose, random LFO and more:
|
- Splitting and Doubling Sounds
- Local off function
- Key Transpose, Random MG Waveform and Compare function
- Two MIDI Send- and Receive channels
- Compare and MIDI Program Change for all 128 Sounds.
