[PD] dropouts on mac os ...

[derek holzer]

Hi Sciss,

fact of the matter is that the Aqua Tcl/Tk GUI on OSX interferes with 
audio processing in an entirely unacceptable way. When I want to do 
serious PD audio work, I boot Gentoo PPC Linux. Quite a bit of 
optimization for video/3d has been done for the OSX version of PD,. This 
was mostly for GEM, as PDP and PiDiP remain quite unoptimized. But audio 
doesn't seem to be a specialty/priority for the developers right now. I 
base this on comments from James Tittle and others when I brought this 
issue up before. I've also gotten feedback from others on this list that 
PD+Audio+OSX is on the border between crippled and useless in its 
current state.

One suggestion which HC Steiner made (IIRC) is to compile PD against a 
Fink or DarwinPorts X11 version of Tcl/Tk instead of the Aqua one. This 
entails some makefile buggery which I haven't gotten around to yet.

Another suggestion is to make sure that the realtime priority flag is 
disabled on OSX with the -nrt flag. This seems to be a workaround in 
some cases, but not a solution to the problem.

best,
d.
