It has the potential to be fun, but sadly it falls short on a couple of very, very key points:
1) No key overlap. It is 100% impossible to get smooth playback, because if you hit one key before releasing the former, the new key just won't play. I understand that this is probably because the plugin does 0% attempt at multiplexing the sample, but really, for the thing to be even remotely useful, this direly needs to be fixed.
2) No fade. No option to either. Meaning that when you hit a key and it starts playing, there's a POP. And when you release, or the segment you're playing ends, another POP. A small fade-in/out could deal with this, but is not there.
3) Almost no way to adjust playback tempo. You can play in the sample's original speed, or half that. Nothing else. No double. No custom. Nothing.
4) No way to make custom cut-points. You can pick between 4th, 8th, 16th, 32nd, and "Auto", which tries to guess where good beat points are. No way to adjust these, or make up your own.
It's a free product, so there's a limit, I guess, to what you can demand. But really, as it is, it's not useful. At all.
