I found the VST had crackling / drops with the UI open. Close the UI and it sounded normal. Well that was the case in Logic running as AU in M1 native mode. Not sure what their problems are. They seems to want to pump out new things while not fixing existing things. I bought the full Amp package about a year ago so kinda upset right now with their lack of M1 VST3 native support. There is just zero excuse at this point as Intel macs are about to cease from being sold, and realistically probably aren’t selling very much.
