The whole point is whether Sequencer and VSTi all internal processes of it count as one process for dual core or not ? Since Fruity or Cubase while loaded shown as one process even if you put thousand of VTS's inside or not.
Any programmer here ?

i know that opening fl into cubase as an instrument want make dualcore enable but opening it rewire its like having 2 applications running so in theory it should work!!!!???
i was testing it today and could not recognise if it realy works i could see more action in the second core but crackles and pops ocured aswell!!
indeed any programmers in here??

Well i guess it's wrong forum! Orange i'm intrested in that case as well, just for Cubase and it's internal shits i will try to ask local programmers. Also best thing is to send an email to your CPU developer and ask them.
Thanks in advance!

In multiprocessing system programmers need to pay attention to synchronizing the data between different cpu's (or cores). That's why by default any program will use only one cpu unless the programmer has done the multiprocessor support (which isn't necessarily an easy task to do).
If you use fl as a vst, fl is used as a plugin, not a separate process - and it's up to the host how well the multiple processors will be used. Single vst cannot be shared between different cpus/cores (this would mean the vst is already MP-ready). So if your fl vst uses 70% of single cpu, it can't properly balance because fl vst cannot be shared between the two. So the other processor would always use at least 70% even if your other stuff would use only 10%...
How does the cubase handle the cpu load when using fl as vst? And can you use multiple fl vst's? This might help divinding the cpu load between the cores.
orange-atropa, if you heared crackling it might be the two programs were running on different cpu's and the data weren't properly synchronized. I'm not sure if rewire is designed to work in such configuration, though it seems odd because there have been a lot of dual core macs already... |
