Marker bar
The marker bar runs the length of your project and contains the tags for markers and regions positioned
along the projects timeline.
Beat ruler
The beat ruler allows you to place events in reference to the musical time of bars and beats. This ruler is
fixed and does not update when you change the tempo. This allows the events in the tracks to maintain
their size when you adjust the tempo.
Time ruler
The time ruler provides a timeline for your project. This ruler can show real time in many different formats.
For more information, see Changing the time ruler format on page 173. The ruler changes with tempo, since the
number of beats and beats per second of real time changes with tempo.
Transport bar
The transport bar contains the playback and cursor positioning buttons frequently used while working on
your project.
ACID also includes keyboard shortcuts for these playback commands. For more information, see Playback
commands on page 19.

project is displayed as possible.
