[PD] Raspberry Pi versus BeagleBoard ?

[Pierre Massat]

Hi Miller,

Thank you for your reply. I didn't know there could be such a difference in
performance between two ARM chips.
It seems very attractive indeed, and i think i'll contact the people at
CCRMA to ask about the latency they achieved. If it's low enough i'll
definitely give it a try.

Cheers,

Pierre.
