Hi Gavin,

You can change tempo bar by bar or even more. Your only constraint is the number 255, I believe..255 as in the number of total bars in your song.

To change the tempo of any bar, right click in the middle of that bar (in the default BIAB GUI) and you will see "Bar settings" in that menu. Left click that, and then carefully change the number to the right of "tempo change to" to whatever tempo you want. BIAB will continue to play at this new tempo until a new tempo change is given in a later bar. Of course, it will play in the original tempo when you start the song and continue in that tempo 'til it comes to your change.

Remember that Real Tracks can sound fairly decent up to about twice their INTENDED tempo. Your song sounds like it's about 120 BPM, so to get the most out of the deal, realize that styles intended for a greater tempo (such as 140-160) will take you easily into the 280-300 BPM range with only instruments that have vibrato on them fairing poorly (that sax vibrato will sound way too fast and weird towards the end of the song--although maybe give it a Benny Hill effect?)

So you could gradually increase the tempo every bar, but probably every other bar would be less work and just as effective. Once you see how easy it is to do, I'm sure you'll come up with a plan that works for you, if you decide to go the 'manic inquisitor route'. Sounds like it could be a hoot.

EDIT: You can even use your already recorded vocal track by importing it into BIAB (Menu<Audio<Import Audio<Browse for file) and if you did this it's best to set up your vocal with the same amount of "lead in" as the rest of your BIAB tracks or your vocal track will be out-of-sync. The default is two bars. And unless I'm mistaken it will change your vocal's tempo along with everything else. I'm not sure if this would be a better choice than you actually re-singing the song, but just so you know..
