In the dialog box that you get when you right-click on a note, the Duration is measured in beats then ticks. What you need to know is that BIAB uses 120 ticks per beat.

So, if you wanted a quarter note, this Duration would appear as 0 beats, 90 or so ticks. Using a value of 80 to 100 will sound the note almost a beat worth, but also give a space (rest) afterward so that it would not run into another quarter note starting on the next beat.

If you wanted a half note, it would be 1 beat 90 or so ticks (which sounds almost two beats).

To get your final note in your example at the beginning of this thread, which is an eighth note on the and of beat four tied to a whole note in the next measure, this would appear as 4 beats and maybe 90 or so ticks (VideoTrack's illustration shows 100, which works).
