I started creating a song in BIAB using _CBOOGS2.sty @ 129 bpm and got to the point where I could lay down the vocals. (Trying to match Elvis is NOT easy !!!). Up until today I was quite excited with the
progress I had made and put it into Cakewalk by BandLab. I thought to then tinker as a means to becoming more familiar with all the software that I have. I wanted to put a slightly more interesting drum track to the song than was provided by the Style that I had used. I turned to EZDrummer and created a new drum track that rocked a bit more with the song. I muted the BIAB drum track and sat back to enjoy.

I find that I'm not on Cloud 9. As the playback progressed, I found that all my hard work on the vocals and editing and rough mixing in Cakewalk was not resulting in me reaching for a glass of Scotch for the right
reasons. The timing/tempo between the BIAB tracks and the EZDrummer track started to drift by the time the playback got to Bar 35-36 (very slightly and NOT from the start) and then by bar 65-66 seemed to 'jump' to a greater degree of difference. The BIAB tracks and my vocal track (which I had recorded against the full BIAB song, had started to fall behind. As I said, it was not at an even rate through the song.

I soloed the BIAB drum track with the EZD drum track so not to be confused. The tempo changes were clearly there. I then needed to discover if it was the BIAB or EZD drum track that was at fault, so I soloed each one
in turn with Cakewalk's metronome switched on. It is BIAB's drum track that falls behind at 2x different points in the song. By the end of the song there is a 2x BEAT difference or thereabouts.

My dilemma now, is how to move forward. Do I try to mess around with squeezing the EZD drum track to fit with all the other tracks, or do I try stretching the BIAB tracks to fit with the EZD drum track. Either way,
it seems that I have to re-do the vocals (which my neighbours aren't going to appreciate !!).

Any constructive thoughts on how I should go about this would be appreciated - but MORE IMPORTANTLY - has anyone else experienced the same issue ?? Has this got something to do with Style built in tempos being squeezed or stretched to fit the tempo of the BIAB song you are creating ??

It would be a shame if this is a weakness of BIAB because I am anticipating using EZD drum tracks in favour of BIAB Style generated drum tracks for most of my songs, simply for the fact that you can have each piece of drum kit in EZD placed on its separate DAW track for individual treatment and mixing purposes.

I look forward to any response.

All the best
