Tempo

The Tempo ruler lets you edit Tempo events one
at a time or according to tempo curves. You can
edit tempo visually in the Tempo Editor, or
make precise changes in tempo using the Tempo
Operations window.
To set the default session tempo, see "Set-
ting the Session Meter and Tempo" on
page 351.
You can use Beat Detective to generate
Bar|Beat markers (tempo map). For more in-
formation, see "Generating Bar|Beat Mark-
ers with Beat Detective" on page 560.
When working with tempo changes and
tick-based material, set the Linearity Dis-
play Mode to Linear Tick Display.
Tempo Events
Tempo events can be assigned to the Song Start
Marker to replace the default tempo (of 120
BPM), and they can be inserted anywhere else
within the session to change tempo.
In Manual Tempo mode, the Tempo track is
ignored and the session plays at the tempo
defined in the Transport window, see "Us-
ing Manual Tempo Mode" on page 352.
