In the process of trying to export all of my folders and drum sets using the Export All Folders and Drumsets from the BBMO, I expected that the BBMO would export the folders as .pbf files but learned that the BBMO exports all of the individual songs in its respective folders.
Why is this somewhat misleading? Because in the context of the BBM and the BBMO, exporting a folder should result in a .pbf file—not individual songs.
While not a bug, this operation could probably be named better so as not to be misleading: Export All Songs and Drumsets
I also found that if a user opens the target folder during the operation of exporting the drum sets, the BBMO will throw a javascript error. Moral of the story, don’t open the target folder while the operation is taking place.
