OVERVIEW Midi polyphonic module can be rackmounted with optional ears. The panel features a segment display, 24 buttons and 2 knobs.
- stereo output (mainly for chorus effect)
- sequencer clock input
- headphones out
- Midi interface
- pedalswitch input (assignable to LFO retrig, sequencer start/stop or patch UP)
VOICE machine handles 8 voices polyphony type DCO based on a custom SGS IC M112B1 which is also the VCA.
The oscillator is digitally controlled DCO which basically features 2 shapes:
- Square with 3 summable harmonics (each has individual gain)
- Square at 16' / 8 ' / 4 '
EX80 can stack polyphony voices into 2 different DCO modes:
- Single --> 1 DCO and 8 notes + 1 pink noise
- Dual --> 2 DCO and 4 notes with detune + 1 pink noise
SEQUENCER manages up to 2 tracks with no special functions but an internal Metronome.
Sequencer clock can be synched to either:
- analog trigger input
- digital Midi clock
EFFECTS just one analog chorus based on BBD TDA1022P with no possible edit; Chorus is not available when using WHOLE DCO detune.
Other machine with TDA 1022 chorus: Elka Synthex / Siel Cruise / Orla DSE24 / Elka Omb5.
EDITOR (for ex80 which is the same) Just a few editors are available:
- Midiquest Ex80 editor (pc/mac)
- GD80 for Commodore 64, absolutely no info but this pic:
