Why does Studio One uses CPU resources (tracks are deactivated!!!)

Hey folks,

can someone please explain me, why S1 (3.5) is using CPU-Power, even if all my tracks are deactivated?

I want to build a huge production template, 1000+ tracks and right now, at 250+ Kontakt tracks, there is no chance, I will work smoothly, because 15% is already used by the CPU (everything is deactivated). I know a guy, he has a much less powerful machine than myself, but runs 3000+ tracks in Cubase with no issues at all. There were no improvements, when I tried with S1 4.5. Same result.

My iMac has 4.2 Ghz / i7 / 4core.

Thank you in advance! :)

The CPU meter doesn't necessarily show how much CPU Studio One is using, but how busy your CPU is and the impact it can have on S1's performance.

If you have high CPU activity when opening an empty song in S1, with no plugins loaded, I'd say there is something fishy going on with your processes.

Have you tried using Activity and sort the column on CPU & CPU Time?

This will often give the best indication of what applications and processes that actually drains your CPU(s).

Choose "View -> All Processes Hierarchically" in the menu bar, to get a good overview.

Sometimes the ucdeamon process fires up and uses a good deal of cpu power for some reason.

When this happens, I just open a Terminal and kill / sighup the process using:

$> sudo kill -HUP <PID OF PROCESS HERE>

And it calms down again...
