I really appreciate the feedback yall. Tomorrow I will start a file from scratch, add parts, wait for the latency issue to begin, then upload the file to Dropbox if anyone wants to check it out. I will be more careful to note what triggers it.
No idea if this is related but wanted to add — a few years ago I bought three plugins from Waves which I ran on the old iMac. When I set up the new Mac Mini in August, the Waves installation process seemed like it had changed in the meantime where I had to install a desktop app and even though I only paid for three plugins, when I browse the Waves item, I get a zillion (demo) plugins in the menu (see attached). Even though I'm rarely running the plugins could this be related?
As far as version, I'm running Logic 10.8, and then Sonoma 14.1.1.
Interesting... gonna try to add and remove those and report back... thanks!
