Classic analog polysynth. Sounds great, even the pre-sets sound great. Extensive control matrix and quite affordable. The only downside is that you need an editor to create/change sounds. And while it does supports MIDI CC extensively, it is not always fluent when doing so. There are some aftermarket firmware updates which make it slightly better but I wouldn't do that live. This is however not really an issue when you're just playing it pre-sets and you can still keep the sounds interesting by using the extensive control matrix.
It will get it's 5th star when someone fixes the response to MIDI CC's.
