Quoting mattn-l@rogers.com:
is this because of portaudio on os x?
yes.
or is there something i can do about it?
start here: http://developer.apple.com/audio/macosxaudio.html
i have too much on my plate right now to rip all the portaudio out of pd and replace it with straight CoreAudio calls. but that's what someone needs to do...
i know that the motu will do 3-4ms with max/msp and reaktor, but not with pd.
there's not a single reason pd can't do the same - all it requires is a little work. pd desperately needs a few more OSX devs that know their shit. we've got the video down cold, and jamie is hard at work making tcl/tk less ass-tastic, but some of the basic pd functionality still needs work. nothing a little OSX native code/APIs couldn't fix.
