I would use taht, yes! Imagine a live DJ, using a lot of samplers and drummers and CDJs. He would aprecciate using a MIDI sequencer like that instead of using a computer under a low light ambient. What about that siclke cell taht most DJs are using, it seems even less usable thant that. To se if something is usable you first must use it. And of course, one thing that may not be useful to you may be to others.And finally, before you critisize something, try doing it better.
