To elaborate a little more on what Dan has said... this is how I understand the Timebase feature (rightly or wrongly!)...

From a BIAB's perspective, 'Doubletime' means that the length of time it takes for a measure to play is double the length of time that the Realtrack would normally take to play a measure. From a tempo setting perspective, this means that the tempo must be halved (i.e. it is set to 65 bpm) if the notes are going take twice as long to play.

As a result of the above, using the 'Doubletime' setting will mean that 4 beats of Realtrack will now be played every two beats of the song given the bar setting of 65 bpm.

In the same way as the above, the timebase setting of 'Halftime' is an indicator for the Realtrack that says that 4 beats of the present song will play in 'half the length of time' that 4 beats of the Realtrack will play. That is, the song's tempo must be 260 bpm. As a consequence, the Realtrack now play its 4 beats over 2 bars of the song.

One particularly useful consequence of using the 'Halftime' setting is that the Realtrack is essentially playing in cut time (i.e. with a 2-beat feel in a 4/4 tempo). This can be quite effective in a backing.
