[Coco] Project Sneak Peek

[S Klammer]

With a $15 Arduino board, we can create and play with short samples in
order to get a feel for Darren's implementation.  As playback is direct
from samples on the SD card, it would presumably be able to play longer
samples and be able to switch those samples quickly.

Darren, glad to see we have new features, like audio, in a single
CoCoSDC-2... and if discussions like this may provide you with other
ideas... I'm still looking to upgrade my CoCoSDC.

I'll leave it at that as I have to prep for work.
