Yeah, that’s with only one of the 32 tracks armed and the 12 frozen, ASIO guard off, 512 buffer, audio priority boost.
The way I determined this was intentionally using an instrument I knew would take up a fair amount of power, then having the Cubase cpu meter and the Mac activity monitor open side by side and going through setting after setting to see which combo provided the best results.
Like I said, I would probably never use 32 instances of a software instrument most likely, and with the above settings I was also able to add four fx tracks with two plugins each on them, and duplicate an audio track six times with two reverbs, a compressor, an eq, and a flanger on them without spiking and dropouts. So for me, for now, that’s acceptable.
It’s a 6 core i5 Mac mini with 32gb ram. I will say it does get warm and the fan does come on, but it doesn’t come on like it did when I tried to run 32 tracks with none frozen and ASIO guard on.
I do wish Steinberg would sort it out on the processor usage. I know Apple has the advantage with Logic being their own, and hence I was able to get 48 tracks without freezing. But I’ve tried them all, and Cubase has been the one for me. Looks like it’s time to start saving for a new Mac Pro (if the CPU is also upgradeable). But for now, the setup I have is acceptable if I make freezing tracks my best friend. (Hey Steinberg, make it so we can freeze more than a track at a time.)
