volcas are a blast i love them but ive outgrown them i think i want something more serious and full, the keys is ok, the bass is sick as hell and i like the filter, the beats are also fun in their own right they can sound great . I may keep them just for how fun they are to jam out on, its so easy to make them sounds good they are just a bit limited tho with only 8 memory spots. I wish the delay on keys was louder but other than that they are great, i fear im gonna have the same feeling i got from selling my monotribe if i sell these little guys which was not good, im still looking for one on craigslist cause i refuse to pay 200 for it again.
even if you just get the bass its a nice bassline synth, obviously not a 303 but the resonance on the volca bass can get quite nice. and with 3 tracks u can makes some pretty nice patterns and screw with them on the fly with active step.
