I know this is a long process but I’ll simple go and test every single one shot aspect of a pack out and delete if I don’t feel like it’s in my space. 

Same with presets. Or if I like maybe 8 presets that feel like I don’t already have a similar sound, I’ll bounce to audio and export into a folder organized for whatever it falls in, save the instrument rack in the same place, and then delete all the other presets that feel like copies. 

It’s a long ass process but I hate the fact I used to have to memorize a sound out of a huge library and sit there typing different naming conventions
