Korg DW-8000
Waveform Synthesizer (1985)

 

Near-classic hybrid analog-digital synthesizer: internal wavetable waveforms are digital while filter and envelope stages are analog.

info KEYBOARD 61 velocity keys with aftertouch.
Main panel features a segment display, 22 buttons, 4 sliders and joystick on the left side.


Back panel terminal connectors:
- Midi interface
- tape interface
- headphones
- main out with impedance switch high/low
- program up pedalswitch input
- portamento pedalswitch input
- damper pedalswitch input

 

 


edit SOUND
main core 8-bits at 2 mHz HD63b03X manages 8 voices polyphony based on - DWGS Digital Waveform Generator System- subtractive synthesis.

DWGS

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.




edit DCO WAVETABLE
the 256 kb ROM (4X EPROMS) contains 16 short-cycled spectral8-bits PCM

rom mrmory DW800 internal waveform list : sawtooth, square, piano, electric piano (x2), clavinet, organ, brass, sax, violin, guitar, electric guitar, bass, digital bass, bell and whistle.
edit It seems to be possible to hack the internal EPROMS to change the waves.




multitimbral PERFORMANCE
the system handles voices in various playmodes:
- poly1 rotates 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

functions 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 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.

cutoff mrmoryVCF offers a primitive Keytrack system with 4 fixed rates: 0 / 25 / 50 / 100 % demo HEAR VCF cutoff resonance






Eg LFO
a single delayed modulator MG (shapes: triangle, square saw-up and saw-down) and 2 modulation destinations:

lfo

- LFO OSC 1 & 2 pitches (not individual)

- LFO TO VCF cutoff


demo HEAR
LFO modulator to VCF





Eg ENVELOPE
3 EGs:

eg vcf - 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



FX 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.

arpeggiator 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.

arpeggiator
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:

upgrade

- 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.
