This synth is great for quick and easy techno sounds, but that's about it. You just can't go wrong for $40 though, and I heard a while ago (hopefully it's still true) that the Junox3 that is in development will be a free upgrade no matter when you purchased 2 (though 3 will cost about $20 more). So if you make any sort of techno do yourself a favor and get this now.
The only problem I have with it is that it seems to have higher cpu ussage than most other synths (especialy for how simple it seems).
