BUG: BBMO unable to complete "Export All Folders and Drumsets" function

macOS 26.3 developer beta 1 (as well as macOS 26.2)
Vivaldi and BBMO 2.0.4

Expected behavior: that BBMO 2.0.4 would complete the export of all Songs (currently still mislabeled as Folders) and drum sets.

What’s happening:

  • the function completes the export of all songs
  • the function stops during export of drum sets on or about the export of file 340 of 462 (or the 27th drum set) and begins to display an error message; when I press OK to continue, every drum set file attempt to export continues to display the same message. The function stops on file 461 of 462 99%) and I have to quit the BBMO because it will not advance beyond file 461.

Preliminary steps to troubleshoot this issue:

  • verified that every song would open in the BBMO; they all did
  • since the function stopped every time with the export of the drum sets, I thought that one of the drum sets might be corrupt so I verified that every drum set could open in the drum set editor. I also checked that a test song could play every drum set. They all did.
