Trying to add a hold at the end of a bar - the bass and drums 'hold' fine, but the guitar does not play at all - I look at the notation, and there's nothing there for the guitar for that bar... Using RT 485 jazz guitar - and it does have # for holds.... am I missing something here?

What version of BIAB? What Build #? (Help, About)
