I use guitar amp sim VSTs. When you open a VSTs editor, at the top there's a Preset list dropdown. None of the sims I use display their presets in this list. Not a problem with VSTs that map their presets internally (Amplitube, Guitar Rig, S-Gear, TH3), but some VSTs don't (BIAS, Kazrog -Thermionik, Recabinet, Redwirez IR Loader). Anybody know what this dropdown list is for and how to use it? Near as I can tell it's kind of like an appendix...
