In a project heavily loaded with Vst’s an Vsti’s and the performance indicator goes through the roof.
Even at a 2048 buffer size i get serious glitches. Ok, to be fair, it is a very heavy project but;
When i check Activity Monitor the percentage of CPU used never exceeds app. 460%.
I have a MacPro5,1 with 12-cores and so the maximum percentage of CPU usage should theoretically be 1200%.
Why is this and what can i do about it?
Specs:
Cubase 7.5.20
MacPro5,1 2 x 2,66Ghz 6 Core Intel Xeon,
16GB 1333Mhz RAM,
1TB OWC Mercury Accelsior PCIe SSD,
Osx 10.9.3,
Steinberg UR28M USB Audio Interface with latest drivers.
Multi Processing - On
ASIO Guard - On
Direct Monitoring - Off
Of course I can start bouncing tracks or freezing but that’s a total workflow killer.
Hope someone can help and if more info is needed please ask! I need this fixed!
My theory is : Its the way Cubase process audio, it’s an old engine originating from Nuendo 1 or 2 , and refined over the years .
More generally, I think it’s also the way computers work with audio.
Audio is a realtime thing so data needs to arrive fast and all “in time” . While other type of processing ( like
compressing a RAR file or decompress) dont need this so that type of processing can use all the cores processing available.
I know its annoying but I think Steinberg will need to reprogram its audio engine from scratch so it can uses all the amazing processing power we have noawadays , maybe for Cubase 8 ?
