It is a cheap little machine so don't expect this to cover all your needs, Behringer drum machines cost about the same and offer much more both in terms of sound and versatility.
The sound is good, the kick can sound ok on any type of electronic music, from hip hop to techno it is usable but this drum voice should have had one more parameter to play with e.g. a pitch envelope in order to sculpt the sound even further.
The snare and claps are ok as well, but the biggest letdown are the toms which are almost inaudible, really a missed opportunity which Arturia doesn't seem to care to fix or even aknowledge (I suppose it could be fixed through firmware update) those looking for a drum machine that can do toms should look elsewhere.
The coolest feature here would be the FM drum (which you can sculpt) and polyrythmic options for each voice.
What makes this machine stand out though is it's small size, I use it for hybrid dj sets (synced from traktor) which also serves perfectly as a clock generator for my Octatrack and keystep, syncs perfectly.
The build quality is pretty good, looks durable.
All in all a cool little machine but to pricey considering what is outhere especially from Behringer.
