yeah.. i just saw a note on an alsa page, that you should set the -p(eriod) to a multiple of 48 when using the emi2|6 (to fit the native sample rate).
More exactly, the reason is, that USB-audio gets delivered in chunks of a fixed time (every 1000 or 100 msecs, I think), whereas standard soundcards have a buffer, that is sized in samples. So if you are running the interface at 48kHz, your period should be a multiple of 48, so that it can match the usb-buffer with integer multiples.
I'm not sure, if what I say above is fully correct, it's just what I remember from talk with Takashi Iwai and I might be wrong...
And actually I can run Pd just fine on my Quattro without using the multiple of 48.
should i avoid reading too much into "ATM"? ;)
the idea of skimping on the interface reminds me far too much of doing purely midi controlled csound/sfront patches.
GUI and DSP are still tightly coupled in Pd, so it's not really skimping, but a hard task, to de-couple both again.
