Apple Soundtrack Pro 2 - Manual (Page 187)

Chapter 5 Working in the Timeline 187
The tempo change created when you score a marker to the playhead is always
instantaneous; that is, the tempo changes from the previous tempo immediately, without
ramping. The distance between the two envelope points determines whether the
resulting tempo change can be heard easily. If the resulting change in tempo sounds too
abrupt, you can edit the tempo envelope to make the tempo change less noticeable.
To score a marker to the playhead:
1 Select the marker’s handle at the top of the Timeline, above the Time ruler.
2 Choose Mark > Score Marker to Playhead.
You can also adjust the tempo relative to a marker’s position by Option-dragging the
marker in the Timeline. As you drag, the red segment of the tempo envelope moves
vertically as the tempo changes. By Option-dragging a marker, you can synchronize the
marker’s position with the Beats-based units.
Note: If you score a marker to the playhead, and the tempo change resulting from the
scoring operation sounds too noticeable or extreme, you can undo the scoring
operation. After undoing the scoring operation, add an envelope point to the tempo
envelope at a point after any audio clips you do not want to be affected by the tempo
change, but before the marker to be scored, then repeat the scoring operation.
Click the marker handle at
the top of the Timeline.
The marker is scored
to the playhead.
