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.

hey folks - just commenting on USB class compliant devices - the Tascam US-800 interface (about $100US) is another class compliant device. it's been shown to work reliably with 8 track recording on iPad. just wanted folks to know there was a cheaper interface option out there, though i'd certainly love to own a Fireface USB interface myself. The US-800 has 6 Neutrik inputs with phantom, 2 SPDIF (Stereo In and Out) and 4 unbalanced outs. it's very light, though, and it may be possible (with modification) to stick the R-Pi inside its case.
hope this might help somebody...

Hi all,
I don't know whether this was mentioned here, but the audio output
throught the built in jack is bad because it uses PWM followed by a filter, no real dedicated dac. You can tweek the settings of Pd for years but you'll never get an good quality sound out of it.
