Apple Logic Pro /LogicExpress Discussion

they have to match because the hardware on board for the G4 and G5 is clocked and timed differently
that would actually slow the machine down
memory access is different
refresh happens at different times
lots of other hardware reasons why it couldn't happen
dual CPU motherboards still share memory and CPU clocks or things couldn't happen in synchronicity


its not that there are different types of multi-processing
think about the fact that photoshop doesn't have to happen in real time
it's done when it's done and you get the result when it's done
with audio eventually everything has to be sent to the d/a in time for real time uninterrupted
audio to result so timing is critical.

I believe the multiprocessing algorithm is handled by the operating system not by logic.



There are different types of multi-processing. I think that Photoshop might actually take a task and split evenly among the processors. But what little I know of Logic's implementation, they split major tasks to separate processors - e.g. OS X and midi on one, audio on the other. 

I always wondered why they had to have symetrical multiprocessors. Why not use a G4/1.4 for the OS, and a G5 for Audio and soft synths.
