instruments as well and I have to very careful about weight and size
(airports and security checks...). The magma isn't big but it's bigger than
the RME break out box. Actually, I share some of your concerns WRT USB for
pro audio (Firwire has wrked fine for me at least under OSX) and I'm hoping
to get better performance from the RME Cardbus than what I've been able to
achieve from USB interfaces.

64-bit is Chuck. It's my feeling that some software (such as flash) has been
less stable for me under 64-bit than what it was under 32-bit, but this is
more of a feeling.

Therefore, you can probably run 32 bit 'pd' on a 64 bit F12 system, w/ all

Thanks a lot for all the helpful tips!
