I got it!!!!
Here’s the procedure. I’ve got separate files of notes in numerical order, produced by splitting them into regions from a single audio file. When Logic does this it sometimes calls the lowest pitch $whatecer_bio .aif so rename it to $whatever_00.aif.
- new software instrument
- change to sampler mult
- mod wheel off
- delete all groups and zones
- gear icon top right new mapping
- new group
- new zone
- zone editor
- pitch key C2
- key range low C2 high C6
- turn off zone prefer splitting zones by silence
- automap using pitch detection
- read root key from audio analysis
At this point, if it’s first time, open library and save this as “empty sampler file”
- drag multiple files into zone window
- change key from bottom to top of usable pitches
- move around any mismatched pitches
- change length and set to forward loop
- rename track
- open library
- save
