CHAPTER 9. TEMPO CONTROL AND WARPING
129
The four Warp From Here commands provide various ways of resetting Warp Markers to
the right of the selected grid marker or Warp Marker, leaving Warp Markers to the left
untouched. These commands are also available from the start marker.
Warp From Here
runs the Auto-Warp algorithm on the material to the right of the
selected marker.
Warp From Here (Start At ...)
directs Auto-Warp to use the current Live Set's tempo as
a starting point for tempo tracking. The strategy here is as follows:
1. Deactivate the Warp switch for the clip so that it plays unwarped;
2. Use the Control Bar's Tap Tempo button to tap along, thereby setting the
Live Set's tempo to match that of the clip;
3. Turn warping on again and use the Warp From Here (Start At ...) command
to tell Auto-Warp to use your tapped tempo as a reference.
Warp From Here (Straight)
tells Auto-Warp that this is a clip with no tempo variations
(common in electronically produced works). Auto-Warp will then set a single Warp
Marker derived from its guess of the le's original tempo.
Warp ... BPM From Here
will also set a single Warp Marker, but in this case, Auto-Warp
is forced to interpret the clip as exactly matching the Live Set's tempo. This is useful
in cases when you happen to know the exact BPM value of an electronically-produced
work and can type it into the Control Bar before warping.
Multi-Clip Warping
When clips of equal length are multi-selected, adding or changing Warp Markers for one
clip will apply identical Warp Markers to all. This is convenient in any situation where several
tracks have the same rhythm, and you wish to alter the timing of each recording in the same
way. A common scenario would be when multi-tracking a band's performance, where the
musicians all play in time with each other, yet the timing itself is in some way awed.
