@AlGrenadine - Totally appreciated. Just sold my AF2 so this timing is excellent. Donated before but will again shortly.
I converted a relatively simple 5-scene preset the other night as a test. After loading the correct IR and adjusting the cab block to find it, I was a bit surprised to find that the preset didn't sound right. I did a quick scan of the blocks and everything looked like the conversion was successful. There were no errors on complaints along the way.
I'm going to update FracTool tonight, try again, and then dig deeper.
General Question: For the presets people are converting, AF2 sound = AF3 sound? I assume YES but have to ask. My issue is likely a simple fix and a result of user error!
