Overview
Main panel features a 16 x 2 display, 35 buttons, 3 knobs and a special joystick ball for vector function control.
Rear panel terminal connectors:
- Midi interface
- main signal out
- AUX out dry



Voice
system manages a total of 32 voices or elements and 2 kind of syntheses or tones:
- AWM PCM samples (16 voices)
- FM frequency modulation (16 voices)

Structure
basic patch combines the tones in 2 different manners:
- 1 PCM + 1 FM
- 2 PCM + 2 FM
PCM are always assigned to TONE A-C and FM to TONE B-D, then elements can be mixed or detune using the apposite vector joystick.

AWM PCM
1 MB ROM holds 128 waveforms coded at 8 bits .

FM
frequency modulation engine is a 2OP with 8 harmonic sinewave variations. FM edit is limited to basic parameters like feedback , advanced functions like algorithm, waveform, frequency and special fixed mode ( DX-7) can be changed only by Midi Sysex commands.

Envelope
each element offers an indipendent EG:
- FM: 4 segments ADSR + 4 times
- AWM: 4 segments ADSR + 4 times

LFO
- LFO FM amplitude
- LFO AWM amplitude
- LFO FM pitch
- LFO AWM pitch

Memory
- 64 ROM patches
- 64 RAM patches
- 16 RAM multis

Review
OK: PCM + FM / raw / cheap / vector
NOT : lack of filter / no deep edit from pannel
"cool machine! for those raw digital textured pads with a touch of dirty FM! my favorite Lo-fi box with Kawai k1m."

cool
