Beat mapping involves two steps:first, you graphically connect notes to ruler positions in
the Beat Mapping track. A tempo change event is inserted at each of these ruler positions,
so that the notes align with musically meaningful time positions in the ruler, although their
absolute time position is unchanged. A beat-mapped project contains the same tempo
variations as the original recording.
Because beat mapping can create changes in the Tempo track, altering existing tempo
changes or creating new tempo changes, you should avoid making changes in the Tempo
track after using beat mapping functions. Doing so will defeat the timing derived from the
beat mapping functions.
In the upper part of the Beat Mapping track, a ruler shows the same time divisions (bars,
beats, and subdivisions) as those that appear in the LCD (and also depend on the current
zoom level).
The following sections describe beat mapping in the Tracks area. Beat mapping is also
available in the Piano Roll Editor, Score Editor, and Step Editor. When working in these
editors, you can see the corresponding (beat-mapped) notes as you work, which can speed
your workflow.
