CHAPTER 14. MIXING 185
A key mapped to any one of the three assignable crossfader positions (left, center or
right) will toggle the crossfader's absolute left and right positions.
Mapping to two of the three elds allows for a snapping back behavior when one
of the assigned keys is held down and the other is pressed and released.
Crossfade Assign
Buttons.
Each track has two Crossfade Assign buttons, A and B. The track can have three states with
respect to the crossfader:
If neither Assign button is on, the crossfader does not affect the track at all.
If A is on, the track will be played unattenuated as long as the crossfader is in the left
half of its value range. As the crossfader moves toward the right across the center
position, the track fades out. At the crossfader's rightmost position, the track is muted.
Likewise, if B is on, the track's volume will be affected only as the crossfader moves
left across its center position.
It is important to understand that the Crossfade Assign buttons do not affect the signal
routing: The crossfader merely inuences the signal volume at each track's gain stage. The
track can be routed to an individual output bus regardless of its crossfade assignment. In
studio parlance, you can think of the crossfader as an on-the-y VCA group.
As with almost everything in Live, your crossfading maneuvers can be recorded into the
Arrangement for later in-depth editing. To edit each track's crossfade assignment, please
choose Mixer from the Envelope Device chooser and X-Fade Assign from the Control
chooser. The crossfader's automation curve is accessible when Mixer is chosen from the
Master track's Device chooser and Crossfade is selected from its Control chooser.
