Calculate the tempo of a selected range
To calculate the tempo of a selected range, use the Edit Tempo command. This command lets you quickly determine
loop tempo in Edit View or change session tempo in Multitrack View. It also lets you change the beats-per-minute
(bpm) value for horizontal rulers in the Bars and Beats time format.

Set the following options, and click OK:

values. Before clicking Extract, make sure to enter a value for Beats per Bar.
Defines the bar and beat information for the selection's starting point (or the current cursor position

Ticks Per Beat
can enter a number between 2 and 3600. For instance, if you enter 32 ticks per beat, a time setting of 4:2:16 represents
an eighth note halfway between beats 2 and 3 in 4/4 time.
