In my setup, all song files are handled by myself. I maintain them on my desktop and rsync them into place on the external SD card of the tablet.
I did give some thoughts to 'switching databases' on the fly, but unfortunately it is a bit more complex than that.
First, it is not just the database, I'd want to switch the settings as well. To be on the safe side, I'd need to switch the complete file trees /data/data/com.zubersoft.mobilesheetspro and /storage/sdcard1/Android/data/com.zubersoft.mobilesheetspro .
I could write some shell scripts to do the switching, start MSPro, wait for its completion, and then restore the switching. I could run these commands using a tool like QuickTerminal. I still haven't gotten that far, waiting (hoping) for Mike to implement a far better solution.
