Korg DW-8000
Waveform Synthesizer (1985)

 

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

keyboard mode

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 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 16' / 8' / 4'
- pitch detune.


DWGS





edit WAVETABLE
the 256 kb ROM (4X EPROMS) contains 16 short-cycled spectral 8-bits PCM waveforms: saw, square, piano, electric piano (x2), clavinet, organ, brass, sax, violin, guitar, electric guitar, bass, digital bass, bell and whistle.
TECH: It seems to be possible to hack the internal EPROMS to change the waves.

multitimbral 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
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.



functions


 

filter 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 %.



cutoff




Eg LFO
a single delayed modulator MG (shapes: triangle, square saw-up and saw-down) and 2 destinations:
- OSC 1 & 2 pitches (not individual)
- VCF cutoff.


lfo



Eg 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


eg vcf

 

 

FX EFFECT a 12 bits digital delay is onboard 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.





arpeggiator ARPEGGIATOR
features 3 modes:
- up direction
- down direction
- custom 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.




mrmory MEMORY
:
- 64 RAM patches
Battery replacement: System works with a 3V CR-2032 soldered to the mainboard.
Sounds library can be saved to Midi sysex dump or to magnetic tape.

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:
- 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.

REVIEW "The sound is nice, some waveforms are wasted. The keyboard version is pretty big, consider rackmount version EX8000 albeit DW has a neat arpeggiator "
