Don't hold your breath, the multi core support just came with the
latest beta of Bidule. I decided to try it out and loaded up a
session on my Apple G5, which at the moment is the only pc I have
around that uses dual processors. My finding was that activating "MP
Assign" for modules induced crackling noise in the input audio. I
tried every combination of MP assignment among VST's and other
modules but could not find a setting with a clean input. I reported
it to the developers. This was a dual G5 and you may get different
results on multi core machines and dual core intels.
If you intend to try MP Assignment it's a good idea to read up at the
Bidule forum on how it works, so you can better chose which modules
to MP assign and which to not.
