Can I permanently create one playlist for the bass- and one list for the synth-band, each with correct input-settings? In other words: Can I save those input settings in a playlist or do I have to readjust them every time in the globals-menu?
Operating levels are global, so they need to be adjusted in the System menu. They are not stored on a Playlist basis. Regardless, switching operating levels takes the same amount of time as switching Playlists. It’s easy.
