I used bb loader to create two playlists directly on the SD Card. When I synchronize the project, does it copy those playlists to the project in my lib?
Do you mean synchronising your project in BBManager?
There the answer is, no. BB Manager doesn’t handle playlists
It seems like the place to create playlists is in BBM. Hopefully they will add that capability.
I typically create playlists directly on the pedal—but mine tend to be short and short-lived
