I just worked on another song and ACW did another great job of breaking it down. What I found was that the song worked best when I started out with 4/4 time signature then changed the first two verses to 5/4, the next 4 set to 4/4, and then repeated this sequence for the whole duration of the song. All the beats fall in the right places in ACW and the bars are correct. However when I go back to Biab now without using the tempo map, it sounds like Biab just ignores the 5/4 time signatures and sets everything to 4/4. If I use the tempo map, then everything sounds bad as the tempo shifts up and down.

Oh - I am sooo confused.
