Subject:        Re: MIDI from PIC devices

 Hi.  Thanks for your reply.  I'm developing a MIDI Brass controller that
has sensors on each of the valves to switch between harmonic series pitch
classes to be stored in an EEPROM and to do freqency counting on the
signal from the instrument using a pick-up mic.  Each valve combination
chooses a set of 16 pitches and the freq. data narrows the pitch down to
one and outputs it via the serial port.  I also will run the audio signal
through an A/D convertor for Velocity data.  Where I am novice is putting
it all together and outputting realtime midi data.  There aren't too many
sources for that, so I hope you can help. 
 For the prototype I hope to send pitch and volume/velocity data.  I'm
not worried too much with pitch bend at the moment, but want to implement
that in the future.  Also, I'd like the option to map an A/D of the
acoustic signal to the breath control feature.  One thing that I'm at
odds with conceptually is note on/off with breath control.  Maybe you
have some insight. 
 I realize that a lot of these are very general questions and require a
lot of explanation in their entirety.  I hope you can bear with me. I
really am in need of some basic starting ideas for the MIDI
implementation.  I'm very familiar with MIDI and the spec.  I just am not
so experienced with the PIC.  My mentor in this project is a PIC
programmer, but isn't too well versed in MIDI.
 What is your implementation of the PIC for MIDI?  It sounds interesting.
Thanks for your interest and I hope you might be able to give me a
starting shove in the right direction.
