So far as I can tell, the fretboard can only be showing while in staff view, so that's not the problem. For what its worth, the CW version i'm on is 2020.1, which should be the latest.
Either way, it 'kind of' works, but is not as responsive as I would have liked, and often skips the first note, and holds other notes, usually at the end. If I get to the bottom of this strange behaviour, I'll be sure to update this thread. I'm also having issues with Cakewalk interfacing with the sound drivers and my A/I that need some troubleshooting when I get some time to research further, so that may be a contributing factor.
In the meantime, the ASCII tab export is good enough - far more useful than the current DAW I use, which has nothing like this at all.
Anyway, I appreciate your help, regardless of the outcome. If I don't get to the bottom of it I'll reach out to Bandlab.
