Hi Jurgen,
Just some additional info using EW PLAY observations with Logic 8. If used as a instance (1 instrument) in Logic 8, 1 core is used. Add a second, 2 cores are used... etc. If you use it as a multi (16 channels) only 1 core is used. EW recommendations are to use multiple instances rather than a single multi in order to spread the workload across all cores. I've tested this and it appears to be the case when viewing the Logic CPU meter which by the way doesn't agree with the OS CPU meter which appears to be spreading across all cores regardless whether I use multiple singles or a multi. In Cubase it seems to spread but I reach a point where my fans Kick in on High Speed indicating that the CPU is really being task even though the OS Meters are only at 60%.
I know you are working with VSL and the reason I bring this up is there seems to be some inconsistency between sequencer CPU meters and the OS meters and how cores are being utilized. Maybe this additional info may help shed some light on your situation.
Thanks for the clarification, Chuck. I indeed was aware of the multiple instances recommendation. This fact is actually evident when taking ReWire out of the picture and using the VSL VE instances directly in Logic 8, which then spreads the load of the convo reverb plug-ins across the Logic CPU meters.
The reason why ReWire is in the picture at this point is, because I am running all my virtual instruments (VSL and EW) on a different workstation and the current version of VE has the habit of clearing all instruments when I change projects in Logic. I have a full orchestra template loaded on the workstation, so my workflow is VE/EW instruments (on second workstation) -> Bidule (running on my sequence DAW where I also have Logic running) -> Logic via ReWire.
Using Bidule in Logic via ReWire has multiple channel support, but seems to be reducing Logic to a single CPU focused app (not technically, but realistically as experienced and outlined in the earlier post), including any convolution reverbs that I may be running in Logic.
So, all this to say that Logic has a bottle neck in terms of using ReWire, which may force a different templating setup.
Can't wait for VE Pro. 😊
