I just did an uninstall/reinstall, problem presists. I know @edm11 you use BIAS, wonder if this makes any sense to you–> If I convert the signal path inside BIAS (while having the plugin open in GP) to a dual path, it sounds fine again. If I revert it back to single, its no good again. I suspect it has something to do with the standalone audio input settings from MONO to STEREO. When I put it to stereo, it sounds similar to the GP plugin behavior.
UPDATE: An hour later… I noticed that if I changed the audio input from STEREO to MONO in standalone BIAS, it would set off a warning in GP that either I am missing an audio input in my original audio interface, do I want a virtual one etc… Now mind you, I did NOT change audio interface. I only changed the settings inside the plugin, which was chained AFTER my audio interface, yet somehow when I changed the audio setting in the standalone BIAS, GP interpreted that as a change in audio interface having one less input. Is that normal behavior?? So essentially, for whatever odd reason that I cannot even beging to wrap my brain around, all this time I was plugging into the LEFT (input 1) in my audio interface, all I had to do was plug in the RIGHT (input 2) b/c all the presets that didnt sound right, sounded just fine once I plugged into the R (input 2).
So I don’t get what made the change from L to R in my audio interface signal since last night AND why if I change the input from stereo to mono in BIAS, does that get interpreted by GP as my actual hardware audio interface’s input was lost from 2 to 1?
