I have checked the archives and there is nothing mentioned about this, and I hope that I am not the only one experiencing this (for trouble shooting reasons!). I have Automatic Delay Compensation turned on in prefs. When I have a UAD-1 plug-in enabled as an insert on an audio channel, delay compensation works just fine *as long as the channel is selected* on the track mixer or in the arrange window. Once another track becomes selected, audio shifts out of delay compensation. Am I missing something? G4 DP533 Mac OS 9.1 LAMP 6.1 UAD-1 3.1 http://www.dylandrazen.com
