Using Warp Markers
In the following sections, we will look at a couple of applications for time-warping samples.
Warping is, of course, an optional property of clips.
Syncing Straight Loops
When you import a sample that represents a well-cut musical loop of 1,2,4 or 8 bars in
length, Live usually makes the correct assumptions to play the loop in sync with the chosen
tempo. It creates two Warp Markers, one at the sample's beginning and one at the end.
A Two-Bar Loop as It
Appears in the Clip
View, by Default.
The Seg. BPM eld displays Live's guess of the loop's tempo; if you happen to know the
tempo of the loop, you can type it in here. Sometimes Live's guess of the original tempo
is wrong by half or double. If so, correct this by clicking on the buttons labeled *2 and
:2, respectively. The sample plays at double speed when you press :2 because you are
changing Live's interpretation of the sample's tempo, which serves as a point of reference
for determining the required time-stretch factor.
Syncing Uncut Loops
When importing a loop that has not been edited into a well-cut loop, Live will play it out
of sync. Suppose there is a portion of silence at the sample beginning, prior to the rst
beat. You can easily correct this by placing a Warp Marker at the beginning of the audio
and dragging it so that it lines up with the beginning of bar one in the timeline. Likewise,
