I got this at a cut price of €20 during sale this summer, which is a steal seeing what this machine has to offer.
It comes loaded with 256 presets, which IMO is particularly usable for trance or Berlin School type music.
The filters have got a nice responsiveness, which makes Crisalys very hands-on straight out of the box.
What makes this program special though is the fantastic sequencer, one really can make some complex and unique loops with that.
My only criticism is that Crisalys is rather heavy on CPU use, and during complex sequences playback can begin to stutter. The adequate provided documentation contains tips for how to sort out this problem, but it goes without saying that you need a better than average machine to fully appreciate Crisalys.
