The ‘Mix Library’ is for the settings of the mix master output channel (eq, processing, etc).
you need to use Scenes to save and recall different monitor mixes for the band.
The easiest way to do this is to create a ‘store all’ scene once you have the basic mixer set up.
then for each song where you have different settings in the iems you use store all to create additional scenes (give them names as per the song etc). then edit out of these scenes all the items you dont want affecting by a scene recall or / and set ‘scene safes’ to isolate channels globally from inadvertent changes. its usually the send levels, mutes, FX units etc that get changed song by song. if you are mixing FOH from the same mixer too then you can use these scenes to control elements of the PA mix if you want.
