Use Tempo Operations
Tempo Operations overview
When Advanced Editing options is selected in the Advanced preferences pane, you can
use the Tempo Operations window for greater control of the project tempo.
You use Tempo Operations to create tempo changes, and edit existing tempo changes. The
window automatically displays the area you’ve selected for editing. Changes are displayed
graphically in real time, as the tempo curve is processed, so you can see the results of your edits.
Open the Tempo Operations window
m Choose Edit > Tempo > Tempo Operations (or use the Open Tempo Operations key command).
Create and edit tempo changes in the Tempo Operations window
You can create tempo changes in the Tempo Operations window using the following operations:
•
Create Tempo Curve: Lets you create numerous tempo change events with just a few
parameters, and provides a smooth overall change in tempo.
•
Create Constant Tempo: Creates a constant tempo in the selected area. The default setting
assigns an average tempo for the selected project section (based on existing tempo change
events).
•
Scale Existing Tempo: Alters existing tempo changes proportionally (scales them). This allows
you to speed up an entire project section, without losing the relationships between any
subsequent tempo changes within the area. Scaling is done by percentage.
•
Stretch Existing Tempo Curve: Stretches or compresses an existing tempo curve.
•
Thin Out Existing Tempo Changes: Reduces the number of tempo changes in the selected area.
•
Randomize Tempo: Adds random tempo changes based on the parameters you specify.
