I had some problems with hdsp:
for example: if you set portaudio with a sample-rate of 44100 it will 
show 44100 but it will set the sample-rate to 48000 (you can check it 
with Daisy.app),
all because the hsdp is a mono mode driver (maybe RME forgot hdsp).
To solve this trouble I've written a new pa_mac_core.c file that you 
must use to compile pd, you can find it here :


or if you want you can use Jack ( http://www.grame.fr/~letz/jack.html , 
http://www.meskalina.it/elementicaotici/dev/audiounits.html ), but 
you'll need a special portaudio driver for RME too (If you want I can 
send it).

I've written an application that load pd simply:
first set the command line from preferences then close and relaunch
