I will not give the characteristics (you already know everything). I think the only BIG FLAT, is the lack of MIDI IN able to synchronize the tempo with other device noon and you can call the loops via program change.

UTILIZATION

easy to use, handling a few hours

SOUND QUALITY

sound quality transparent enough. I use the output of a pre-mixer for my keyboards.

OVERALL OPINION

It allows me to send loops is made live (for the easiest) is pre recorded. The advantage is that you can 'tap a tempo to synchronize a loop sending a drummer and a separate click the batter does not move then exit .. We can also load and play WAV FILES (always with the advantages of the click and time strech) via software (which in turn is really a big Mr. ...) but hey, you get there.
