[PD] Pd Vanilla on Raspberry Pi

This is good news about the TASCAM devices (I see there's a whole series
of them and they're cheap.) I've also heard that Presonous's interfaces
are class compliant, but I've now forgotten who told me that.
I read some months ago on the Raspberry Pi site that it should perform
"about like a 300 mHz Pentium II" - and the fact that it runs the phase
vocoder patch without running out of CPU cycles roughly confirms that.
For those of you who are getting skips in the sound, I'm curious if Pd
is printing the usual messages like:
priority 96 scheduling enabled.
priority 98 scheduling enabled.
on standard error when it starts up -- if not, it would be worth trying
to figure out how to get Pd to be able to get real-time priority which
might fix some of the problems.
