MIDI input objects

Max has dedicated objects for parsing each particular type of MIDI channel message coming into the computer, such as notes, pitchbends, controllers, etc., and it has corresponding output objects for formatting and transmitting MIDI messages to be sent out of Max.

Transpose and invert MIDI notes

This patch demonstrates a couple of very simple sorts of transformations that could be imposed on incoming MIDI pitch values before sending them on to a synthesizer. One is transposition, achieved by adding a certain number of semitones to the MIDI pitch value (and sending it out with the same velocity values as were in the incoming note messages).
