Overview
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
- 3 pedalswitch inputs
Voice
8 voices based on DWGS- Digital Waveform Generator System subtractive synthesis- each DW voice is composed by 2 DCO oscillators + 1 white noise circuit.
Wavetable
the 256 kb ROM contains 16 short-cycled spectral 8-bits PCM waveforms
Performance
the system handles voice in various playmodes:
- 2 polymodes
- 2 unison modes
- aftertouch be assigned to filter, amplitude or LFO depth
- 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 IC X 8 NJM2069AD , lowpass resonant VCF at -24 dB/Oct and polarity inversion.
LFO
delayed modulator MG and 3 destinations:
- OSC 1 & 2 pitches (not separate)
- VCF cutoff
- time delay
Envelope
- EG1
VCA: 4 segments + 2 times (ADBSSR)
- EG2
VCF: 4 segments + 2 times with polarity inversion
-
autoBend is a s imple pitch EG (OSC1 / OSC2 or both) 2 direction modes: up / down
Effect
12 bits digital delay with 2 - 512 mS time range able to generate short delays and chorus.
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.
Memory

Review
OK: filter / arpeggiator
NOT : bulky / some DWGS are wasted
"The sound is nice, some waveforms are wasted. The keyboard version is pretty big, consider rackmount version EX8000, but DW has a neat arpeggiator! "
