Latency may be an issue on a Rasberry Pi. You can subtly feel a latency of 10ms-30ms in the sound when playing a guitar. And over 30ms is outside the Haas effect zone, so is glaringly obvious. Rasberry Pi also has no audio input, and only HDMI audio output, which is digital. Guitar amplifiers take an unbalanced high impedance analogue input. I don't think embedded OS is as important as the programming OS. I would certainly like to see the other OSes supported for developing patches.

Turns out there is analogue audio out on the Rasberry Pi. Sorry about that. No inbuilt audio in though.
