Global Tracks
All linear editing windows feature global tracks, which are displayed just below the Bar
ruler, when opened. Click the disclosure triangle to the left of the Bar ruler (labeled Global
tracks) to view the global tracks.
• Marker track: Contains markers, which are used to label bar positions and parts of the
project. Their length, text, and color can be edited freely. For further information, see
Working with Markers .
• Tempo track: Contains all tempo changes in the project. For further information, see
Using the Tempo Track .
• Beat Mapping track: Allows you to assign a bar position to any musical event (both
MIDI notes and distinct accents in audio regions). This makes it possible to adjust the
musical timeline to the original timing of a MIDI or audio region that has been recorded
rubato (free time, including speeding up and slowing down), or just without a
metronome click. The audible outcome remains unchanged, but the resulting display
will fit the musical timeline. For further information, see
Beat Mapping Regions .
• Signature track: Contains the basic key of the project, along with all time and key
signatures, as they are displayed in the Score Editor. For further information, see Working
with Time and Key Signatures .
