Overview
KEYBOARD 61 velocity keys with aftertouch.

Back panel terminal connectors:
-
Midi interface

Voice
main core is a RISC manages up to 64 voices or TONES.
A basic patch is composed by 4 tones PCM samples
Wavetable
ROM contains 448 PCM at 16-bits waves split into 2 main families:
- 193 PCM percussive and chromatic one-shot
-
255 PCM instruments
Structure
The tones can be combined in 10 different signal paths (algorithms) or structures inspired from Roland D-50 technology These are pre-fixed audio patch that connects the 2 pair of tones into variable setups mixed with audio elements such as amplifier, filter and 2 digital processe
Filter
TVF Time-Variant digital Filter offers 4 modes:
- lowpass
-
bandpass
-
highpass
-
peaking
LFO
2 modulators, they do provide 7 shapes (triangle, sinewave, sawtooth, trapezoidal, 2 random modes and sample-hold) with adjustable symmetry.
Envelope
each TONE offers 3 EGs:
- EG1 amplitude: 4 segments + 3 times, 8 velocity curves + key follows option
- EG2 filter : 4 segments + 4 times.
- EG3 pitch 4 segments + 4 times, keyfollow + random pitch
Effect
Digital DSP: reverb, chorus, distortion, overdrive, phaser, EQ, Leslie, tremolo, flanger, delay, and pitch-shifter
Sequencer

common issues are: dead display (condensers) and tact switches replacement
Review
OK: pads / sequencer
NOT : unreliable / a bit outdated by new roland synts
REVIEW "it's another classic JV rompler workstation, not the best of the series - but still worth a try. Pay attention to frequent issues."
