However in our test we didn't see any obvious error message with UAD. Can you repro that in a simple project with just 2 or 3 UAD plugins in a track? Also please indicate the specific error message and which plugins throw the error.
in my experience,
UAD errors pop up
when I drag copy plug-in(non-UAD) into another track which is loaded UAD.
when I drag copy UAD plug-in into another track which is loaded non-UAD plug-in.
when do nothing (during mixing, rest few minute. many plug-ins loaded)
Pop up messages which I experienced.
UAD sample rate error
UAD disabled error (communication non response)
I do work one mixing project after install new update.
After I found this issue, I turned off plug-in load balancing.
There is no issue but cpu performance is very unbalanced haha.
I turned Plug-in Balancing function on now for testing, Error message pop up again in few sec.
