Very ergonomic to use with its plethora of control knobs in real time, it suffers from the syndrome DX7, that is to say that for editing patches, given the tiny size of the screen and the large number parameters, it is better to go through the editor on the computer.

The supplied software is quite usable but a bit tedious. SoundQuest is compatible with the beast, and more pleasant to use.

The manual is available in French on the net and comprehensive enough to remain.


Even today in hardware synth I have not found better overall for the hard trance and electro, and it has its uses in other styles of electronic music. If you are looking for grand pianos, strings or other "real instruments", look elsewhere.

The touch is still perfect after more than 20 years of almost daily use. expression is excellent, better than a lot of synths today, and polyphonic aftertouch is a nice addition.

There is a secret weapon, wheel morphing between two scenes, which allows mixing and switcher two completely different sounds.

The ribbon of expression is a little more, and the breath sensor.

The effects are good, there are subtle to the contempt.

The arpeggiator is very good in my opinion.


I bought new in its release and I still have it, while quite a few other synths have passed under the bridge, that says it all: o)

I had tried just about everything he had at the time and it is he who has come home with me. I rachèterais eyes closed.

This is a great synth, it stands up to a lot of competition now and the number of controllers available makes it a good master keyboard too.

It was a bit expensive at the time, but is now found with two expansion cards already installed at attractive prices.
