[sdiy] Microcontrollers

[Theo]

I agree with Jim,
IMHO AVR is a very nice uC for midi.
Should forget about the RTOS tough especially when timing is important, any
overhead is well, err, overhead.
Assembly coding is a breeze not in the last part because of the wealth of
registers available.
Me like it :)
