Out of the blue I suddenly have white noise/hum when using certain Kontact instruments in Logic Pro X, but not others. I hear it if I play back a recording, and I hear it if I am just playing while not recording. I often wont hear it until I hit a key on my keyboard, and then it starts up, and then it will go away maybe 4 seconds after the midi part ends. Interestingly, if I go into Kontakt and on the upper right hit the "FX" button to turn them off, it goes away. I can still hear the part play but without the hum (and the effects).
I have not been able to identify a ground loop issue. And if there was one it wouldn't make sense to me that it would only come on with certain instruments/samples, and not others. And I don't know why it would go away with the FX button.
I read other old threads I could find. One guy said his went away when he turned ON auto quantizing, but that didn't work for me.
I tried opening a brand new project and it did it there too.
I did recently upgrade to a new Macbook with the M1 max processor, and am opening with Rosetta. But the weird thing is it all seemed fine at first. This popped up all of a sudden.
Any ideas? Have lost many hours.
