Hi Miller,<br><br>Thank you for your reply. I didn't know there could be such a difference in performance between two ARM chips.<br>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.<br>

I could be wrong, but I believe the Beagleboard is ARMv7 and the Pi is<br>
ARM v6 - so BB could easily have twice the floating-point erformance of<br>
Pi. I'm not sure why and whether there would be any difference in Jack<br>
for the two. I believe (but am not sure at all) that BB doesn't have the<br>
same USB problems the Pi has. All in all it's still a very attractive<br>
possibliity, perticularly since the Stanford people have tested and exercised<br>
it thoroughly.<br>
<br>
cheers<br>
