Hi thank you for your quick reply. To be clear, I am not attempting to use Fl studio as a real time controller (although that might be cool!). I am using Fl studio as a composition tool, saving the composition as a midi file, then importing the midi file in BB manager to create a new song part. I was hoping someone else was using the same workflow and had already worked out the bugs.
I really think the issue is on the Fl studio side - where the midi output file isn’t assigning the notes to midi numbers that BB would recognize as valid.
I think I may have a work around by converting to piano first, aligning to the piano notes that match the correct midi numbers, then importing into BB manager. Will report back if that works
