First, Mel isn't likely to help. Remember, he quit TI calculators for 
"bigger" things. 

That's not my piont though. I have been sating MIDI like standard, not 
true MIDI!!! all we need is an I2C 8-bit paralel chip or two, and a wave 
form generator such as the MAX 038. Maybe we can find a serial 2 wire 
waveform generator, but I doubt it. Personaly, I'd use the SID chip from 
the commodore 128. It had 3 chanels, 4 waveforms (sine, square, 
triangle, and noise), and it has 4 bit audio amplitude control (volume 
from 0 to 15), and the wave form is 12 BITS!!!. That's high quality. You 
don't need much to control it Atack, sustain, reverb, decay, waveform, 
pitch, and volume level. The SID chip can emulate a Piano and play a not 
with a few commands!!! I've set it up to play music before with piano 
carring the melody, harpsichord on harmony, and noise to simulate drums! 
It's a pain, but no more dificult than sheet music in numbers! Try it! I 
can get you pinouts specs, everything!!! You can even control audio 
levels from an input, using it as an amplifier!!!

We don't need MIDI, just something that works like MIDI, where you 
define instruments and then send notes and sustain times and stuff 
rather than digitizing music. I but you could get it to work at uner 1 K 
per second!!!
