Create a blank song in Folder 1, Position 1. Enter just a Null or Empty in the main loop slot. I have attached a file that can be used. Select your desired Drumset as the default drumset for that song. When you start BBM, this will be the song and Dumset loaded.
I hesitate to give you another tip, since nothing seems to work, but you might want to take a look at this thread, post #2, and try the process beginning in step 5. If that fails, I got nothing else for you. I edit kits all the time using this process, and I do not experience the problems that you do.
Drums Sets Percentage indicator now shows 99% when I start BBM and load the correct drumset just like when I made it
Don’t really know exactly what made it work though, maybe after I deleted folders with older drumset names I’d used earlier but don’t use anymore in the Workspace folders.
I also tried open/importing drumsets several times.
Thanks for the tip !
It may come in handy for future issues !
