Playback and Recording : Record Setup : Setting the Session Meter and Tempo : Using Manual Tempo Mode

Using Manual Tempo Mode
In Manual Tempo mode, Pro Tools ignores tempo events in the Tempo track and instead plays back a Manual Tempo. This tempo can be set with the Tempo slider, or if you are not sure of the actual tempo, by tapping in the tempo.
While you can adjust the Manual Tempo during playback, doing so momentarily interrupts playback.
To set the Manual Tempo with the Tempo slider:
1 To view the MIDI controls in the Transport window, select View > Transport > MIDI Controls.
2 In the Transport window, click the Tempo Ruler Enable button (Conductor) button so it becomes unhighlighted. Pro Tools switches to Manual Tempo mode. In this mode, any tempo events in the Tempo track are ignored.
3 To base the BPM value on something other than the default quarter-note, click the Tempo Resolution selector and select a different note value. (For example, if you are in 6/8, select a dotted-quarter note.)
4 To enter a new tempo, do one of the following:
*   
Drag the Tempo value up or down. For finer resolution, press Control (Windows) or Command (Mac) while dragging.

To lock in the new tempo:
*
Take Pro Tools out of Manual Tempo mode by clicking the Tempo Ruler Enable (Conductor) button, then set the default tempo for the Song Start Marker to the new tempo.
