Hello everybody. I am having CPU problems (clipping etc) when using Unify standalone, also in Logic Pro. I just got the BBC Discover Unify library and in most of the sounds I am having the situation, the %CPU goes to 218.0 and above in my Activity Monitor. Is there a way to solve this with some kind of configuration please? I have tried changing the audio buffer size but still, no luck. I am using a 2014 Macbook Pro 15 inch i7 2.8Ghz and 16GB of Ram (MacOS Catalina). Thanks in advance.

The BBC Symphony Orchestra plug-in is a bit of a CPU hog, but your computer should be quite adequate to use the Discover patches. (BBC Core is quite a bit more demanding.) For the MacOS Activity Monitor to show CPU above 100% is not necessarily a problem; this is just something it does on multi-core systems.

Please switch on Unify's own CPU meters (click the concentric-circles icon at the very bottom center of the Unify GUI and choose "Toggle CPU meters"), then take a screenshot of the GUI when you hear the audio problems, zip and post here as an attachment.

@getdunne Hi, thanks for the reply. It's really weird, it goes to red sometimes even without playing a note.

My best guess is that some other process on your Mac is using the CPU. Please check in Activity Monitor when Unify is not running.

Do you have any kind of antivirus/anti-malware program running?

CPU metering is very subtle. See https://pluginguru.net/unify/manual/doku.php?id=cpu-meters

Spitfire's BBCSO is a definitely a  CPU hog.   However, in Logic Pro X, make sure to optimize/increase your I/O Buffer.  I set mine to maximum 1024 samples and that does the trick, plus I moved all my sample libraries to an external SSD Hard drive.   I'm able to stack Insta Score & Flutes of Paradise and play without any issues 99.9% of the time.  Below is the link to avoiding system overload in Logic Pro X.
