[sdiy] kinda interesting audio arduino thing

[Jason Proctor]

IIRC, there are analogue pins on the basic Arduino board that could 
be used for CV ins and outs.

the thing looks sufficiently interesting for me to pick one up. 
initially i'll probably write some CV and clock processing goodies 
and park it behind a modular panel. then i'll move on to MIDI and 
audio later. i'll advise on progress as and when it happens.
