[PD] OS X & motu 828

[Olaf Matthes]

Hi Miller,

I got it - sort of - working using -audiobuf 20. But audio sounds a bit
'distorted' (like buffers skipping some data...). And I get some really broken
stuff out of adc~ with -noadc set! And I can't use 48kHz, just 44.1.

BTW, there are some other problems on OS X: when turning on Audio using the
button in the main window I get 'can't read "Priv(repeated)" no such variable'.
Turning on audio via the menue or using a message "; pd dsp 1" works.
Second thing: "error: #keyname: couldn't unbind" sometime appears in the
console. I haven't figured out jet when and why...  Ah, and I'm using Tcl/Tk
8.4a4 from sourceforge.

Olaf
