I thought the 2.3 version of the UAD-1 plugs was supposed to fix the cracks and pops associated with the combination of the UAD-1 and the Delta series audio cards. If anything it's much worse. I am getting cracks and pops when zooming in and out as well as the regular crackles and sometimes it just completely distorts. I tried going back to 2.2.6 but it didn't help. I get the crackles and pops with Studio Vision Pro as well. any ideas? thanks Holmes Ives
