I've been wondering about multicore issue a bit,
it seems ProTools have managed multi CPU (multi DSP) operation with
their DSP Farm cards for many years (decades). As a result it also
seems that they managed the transition to multicore computers pretty
easily.
I do not know the technical details, just thinking "conceptually"
about the issue.
Is there anything in terms of general approach that we could "borrow"
from ProTools to make Csound multicore enabled ?
