I have used it for several weeks. It is similar in concept to  Rebirth (3 and 1 TB-303 Drum Machine), but it looks like a mini Orion too. I love the interface. It is almost perfect, it was quickly CASC all functions. I'm impressed because everything fits in so little space! My only wish is that it had a  melodic instrument sampler like in Syntrax for example. The PC version will convert your compositions to WAV but not back into MIDI, which is a shame because it can be used (for example) to create rhythmic patterns when you're out and about and want to use them in a more powerful software. Well, I'm watching to create a backup utility that would allow this MIDI conversion. The quality and price are great although somehow Syntrax is free. Anyway, I prefer Phoenix Studio and I think it is a great choice!
