GREAT APP!

It works, its powerful, and its fun. Have successfully triggered synths on a laptop computer WIRELESSLY (works better on a dedicated peer-to-peer network). The MIDI implementation is outrageously robust. The best thing is that its really musical and sounds great the minute you start using it. It can be used as a toy or a (fairly) pro MIDI controller. I can see why it gets good reviews. Easy to get lost in for hours cause its so sweet to listen to.
