Pros:
1. Fully customizable: inputs, outputs, footswitch functions, external footswitch or midi, recording options, etc. It will CERTAINLY adapt to your own workflow (you just have to spend some time with it and set it up right).
2. 2 tracks.
Cons:
1. Not that big of a deal but the drum patterns could be a bit more sophisticated and let you import your own pattern, which it doesn't. the 3/4, 5/4 and 7/4 patterns are VERY unconvincing though, they just feel like a chopped up 4/4.
