[sdiy] Release Velocity & Poly Aftertouch -- Too Much?

Because with no release velocity, you can use a note on with velocity
zero as a note off.  So you just send a note-on and a string of 
note number and velocity data.  If you start using release velocity,
you have to start using both note-on and note-off status messages
as well as data, so less running status and up to 50% more data.

This is only significant for a simple system sending mainly note 
messages on one channel, but that was often the case in the early
days of midi, and that's when release velocity fell out of favour.
