Kontakt 6.7.0 - CPU Spikes in Logic (Universal)

re201spaceecho Member Posts: 5 Noise

Hey folks! I'm having some trouble with Kontakt 6.7.0 in Logic Pro 10.7.2, running on a new MacBook Pro M1 Max, 64GB RAM.

I've been testing Kontakt in a small session with only 3 instances record-armed. When running Logic natively, I'm getting CPU spikes on 2-3 cores, and audio drop outs, sometimes clicking. My Logic settings are a 512 buffer, with all high performance cores enabled (8). Running in Rosetta solves the issue.

What is strange... is that I ran a much more stressful test with Kontakt in another session with 18 instances of Kontakt, including CPU heavyweights like Slate + Ash, CineStrings, etc. It seems to run well, even with live tracks record armed. Not a realistic test, but interesting nonetheless. I'm seeing load distribution across all 10 cores, maxing out around 75-80%.

What could be the issue here? Any insight would be helpful!

My libraries are located on my system SSD, but they were copied from my external SSD and not re-downloaded from Native Access / other downloaders. Could this be related...?
