Hi Rudy,

Your detailed explanation helps a great deal. I can now appreciate your problem.

As I see it, the problem arises because converting 80 quarter notes per minute to dotted quarter notes per minute gives (2/3 * 80 =) 53.3333333333333. It's that decimal place variation that is causing the issue as BIAB cannot accommodate decimal point tempos.

The quarter note equivalent of 53 dotted quarter-notes per minute is (53*3/2 =) 79.5. My calculations suggest that if you work at 79.5 in Cubase rather than 80, the BIAB files at 53 should match (if you ignore the 2 bar intro in BIAB and align the audio).

Since the alignment is not out by a great deal, you should also be able to time-stretch or time-shrink your BIAB wav file to match with file in Cubase.

I use Reaper and in a situation like this, what I would do is... align the left sides of the two tracks. I then go to the right end of the file I want to stretch/shrink, press and hold CTRL+ALT and drag the end of the faulty file to match the other file.

Below is a video clip that I found regarding time-stretching in Cubase.



I hope these thoughts help.

Regards,
Noel

NOTE: the ratios 2/3 and 3/2 arise because 80 bpm (1/4 notes) has a single beat consisting of two eighth notes, while 53 bpm (dotted 1/4 notes) has three eighth notes per beat.
