program change in detonate

The last two inlets and outlets of detonate can be used to record and play back any arbitrary data you'd like to be associated with note events, so you could use those to record and play back MIDI program change values. Here's an example that uses those one of those inlets/outlets to record and play back MIDI panning data. (The example is somewhat abstruse, but if you just focus on the use of that one inlet/outlet, it should serve to illustrate the idea.)
