Maybe this approach could be better:
- Open my Daw (Reaper)
- Go to Band in a Box in Reaper
- Drag my BiaB file to Reaper as a first track
- Create a second track
- Go to Kontakt and load my VST Bluegrass Banjo V3 (Boulder Sounds)
- Create just 3 notes in this second track
- Play both tracks together
