[sdiy] Another Amtel-based synth core

[Neil Johnson]

Well, this is turning into quite a "me-too" concert.  So, not wanting  
to be left out, I'll just chip in with my ATMEGA8-based DCO I put  
together for my Jen SX1000 restoration.  Ok, I did this a couple of  
years ago, but its still going strong!

Details here:

Does keyboard scanning, MIDI receive, interrupt-driven portamento, uses  
one of the timers to generate a clock output while being driven from an  
external high-frequency VCO.
Nothing quite so exciting as filters and envelopes though :-)

Oh, and all the code was written in C, using the AVR port of GCC (I  
used the "WinAVR" distribution) and the rather neat and tidy AvrX RTOS.

Cheers,
Neil
