I checked but could not find a native BiaB solution, however I don't work in audio inside of BiaB so maybe others with more experience can help. But if there isn't any native BiaB you could detune each track -33 cents by using Melodyne as a plug-in. If you don't have Melodyne then DL a free auto-pitch plug-in like Grallion 2:

I hope this helps and good luck.

PS - you may be able to detune by using a precise pitch bend number via automation. Again I don't work with audio in BiaB so I am assuming pitch bend automation is available.


Why is it that doctors call what they do 'practice'?
If flying is so safe, why do they call the airport, the terminal?
