Problems with rex2 files & EXS in 9.1.1

Everything works as expected when importing rex2 files, creating an EXS instrument, & saving it, but as soon as I quit & re-load a song, it seems to loose the rex2 files & only load the associated audio file (without the chops).

When you load a REX file, EXS converts it to an EXS instrument and creates a midi region in the Logic Arrange named to the EXS instrument. This midi region contains the midi slices and it can not be saved inside EXS. You can save it in the Logic project or select it and export as Standard Midi File (SMF).
It is a matter of organization if you want just to convert your Rex files and organize their SMF regions. For example you can create a folder named "My Rex Midi" and place in some conformable place - dock, desktop even Logic Help Menu ( you need to modify a help text file in the Logic resources to show it there ).
The idea is when load a certain EXS (previously rex converted instrument) to drag & drop its corresponding midi file from "My Rex Midi" folder to the Arrange EXS track. The "My Rex Midi" can contain subfolders according your Rex file tree organization. It is some kind of workaround if you remember the old Stylus way.

This midi region contains the midi slices and it can not be saved inside EXS.

Actually, the MIDI data is stored inside EXS converted instruments irc, and you can recreate the MIDI region at any time - see the manual:

"You can generate new MIDI regions at any time from the imported EXS instrument (see “Generating a MIDI Region from a ReCycle Instrument”), so feel free to modify or delete the region."

The MIDI data is stored in the EXS as metadata, and is always there, so you don't need to store MIDI regions independently. You just use the command to create a MIDI region on the arrange page when you want to use the MIDI data from that imported Recycle EXS instrument.

Right, I have not used the "Recycle Convert" menu for very long time obviously.
Thanks for the clarification!

If you use a lot of rex loops, I'd take a serious look at Stylus.
