Synthtiseur analog (modlisation), vocoder, arpgiateur, effect block ... there is plenty to do.
wholesale: 3 OSC, LFO 2, 12/24 db low pass, etc ... I will not repeat the data sheet!
It can store 400 programs.
The audio connection is complte and noon (between Mono / Stereo out, midi in / out / thru).

UTILIZATION

Relatively simple to take in hand, the edition of sounds can not be easier and direct all potentiomtres.
Some blame the diodes notch ... I think it's good because I trs n'achte not the hardware for the notches, menus and all the mess we have on a computer screen.
The manual is clear trs with some "grip" for easy startup.

SOUNDS

The sound is the strong point ...
The presets are excellent and provide a good working basis.
Sound (general) trs is good and the possibilities are wide: as comfortable in the flat sheet and in the deep bass or aggressive leads.
It might be an AIM high-pass filter in addition to two low-pass, but that's the quibble.

OVERALL OPINION

Hard to beat ... there must be at once more for having this level among competitors. Anyway the sound is really excellent and when we find it used (like me) the case is even better.
A small dtail: to save space (1U!) There is no on / off button.
