Just a followup for Andy T .. If I understand what you do is to create a wave file in BIAB and then bring that into RB. What I did was a little different. I brought the BIAB file into RB so it brings in the chords, etc. Then I picked a midi track like piano and there is an option to convert that to audio track. Once I did that the audio track lined up with the drums. But the solution from Mac also worked to get the midi and audio tracks aligned. But now I have the issue of a midi track not generating the full 2 bar ending. Just the 1st bar of the 2 bar ending. The real drums do complete the ending.
