that's good news.

the thing that sort of concerns me is that portaudio seems to need
patching to support every new device release for OSX. this is not
good, and pretty much defeats a lot of what CoreAudio is meant to do.
plus the AudioConverter routine adds another buffer to the I/O chain
which might mean at least another 64 samples of latency on both ends.
pd already has a relatively high latency on OSX right now, so this
isn't going to help out.

CVS is a good place for testing and experimentation. go ahead and
commit it and i will compile a version and give it to some people
using devices like the 828 and report back.
also, i would be interested in working on a direct CoreAudio
implementation for pd. i'm tied up on a project until the second
week in April, so i won't even take a look until then. anyone else
interested in doing this?
