I fired it up and messed with it. The polyphonic nature of it makes it quite forgiving of sloppy playing. It tracks well all the way to bottom. The arpeggiator is lots of fun, but with no tap tempo option I cannot see how I can use it in the real world. I had hoped that aspect would replace my Boss Slicer. It wont. There is a movable filter doobrie on it but that is universal so if it is set for one sound it is set for everything so that is not so great. The sounds are fine. The sustain pedal function is the bomb. The lack of tweakability which is programmable means it is not for me.
