Looper upgrade. This one has 40 separate drum tracks that could be added to the loop. Also, has an auxiliary input where you can sample from existing materials. Also can run directly to a computer's USB to record if needed. My only concern, is whether or not it is simple enough to use. I don't like equipment with a heavy learning curve. I want to be able to plug it in and make it work. The YouTube tutorials I have seen on it seem to be relatively easy to follow. We'll see how this adds into my board.
