New to Reaper. When I try to load the project template linked in the OP, I get this message:

 

 

What should I be doing here? I assume there are some additional files I should get, and I’d put those in an “RBN” folder before proceeding?

 

I’m also having trouble understanding this part listed in the instructions:

Also included are note name files (BASS note names.txt, etc). These can be useful when importing bare MIDI files. Right-click in REAPER’s MIDI editor, and select File / Load note names from file.

I think I’ve gotten into the MIDI editor (I dragged a MIDI file onto Reaper and it opened a bunch of tracks), but when I right-click I’m not seeing a “File ” menu.
