I really don't know where to post, but at the end I have to admit this is a technical issue.
I'm currently running PD under OSX with an Edirol FA66, and I have two questions for you, wise men!
-- Does PD use all resources of my mac?
-- That's true that the maximum sample rate is, in PD, 48 kHz?

I've noticed that setting the audio interface on 96 kHz I hear tons of clicks coming out, even changing latency duration; do you know why?
Probably will help changing some flags at the startup, but in this my ignorance is abyssal.

Thanks wise men, have a good day
