CocoTex,

When you record a track on your Zoom R16 are you creating space for the two bar lead in BiaB requires? When you listen to a BiaB recorded track on the Zoom R16 while you are recording a new track you will hear a two bar count-in generated by the R16 and a two bar count in generated by BiaB. Even if you do not include the BiaB generated two bar count in when BiaB renders the track, two bars of empty space need to be present at the beginning of the R16 created track if the R16 track is going to be imported into BiaB.

Another thought is your R16 recording settings may not match BiaB settings. BiaB uses 16 bit depth at 44.1Khz sample rate. You indicated the R16 bit depth is 24 bits. That's fine as BiaB just ignores the extra bits but what sample rate do you have the R16 set at? A mismatched sample rate can cause pitch or timing error.

Here's another approach to mixing you may like:

Lower all track faders to 0 volume.

Raise the drum fader until the drum volume level is comfortable.

Raise the bass volume level until the sound of the bass blends well with the drums. Can you clearly hear the kick drum? Does the kick drum hide any of the bass notes? If so then you need to adjust both track EQs until everything can be clearly heard then adjust your fader levels again to blend the tracks.

Add another track and repeat the last step.

By the time you're finished adding tracks everything should still be clearly heard and at the correct volume level relative to each other.
