So many Kontakt libraries have the same array of control knobs across the bottom that I thought I'd just assign knobs on my Artutia Essential 49 keyboard to control them. I set them up with MIDI Learn, and they work great, but I can't figure out how to save the assignments. Maybe they aren't supposed to be saved. Is this some esoteric lesson on the shifting sands of existence? Maybe it's a user error. Help, please.
