Tracktion 4 Reference Manual

Figure 6.2.1 shows a tempo curve, the current time signature, and the current key. The time signa-
ture and key are shown on the left of the image.
Once the global track is visible you can also use it to easily add and adjust tempo changes. The
curve shown in Figure 6.2.1 is the tempo of the edit. Note that the spacing between the bar divisions is
proportional to the tempo at each point on the curve.
You can insert new tempo changes by either double-clicking on the curve at the desired insertion
point, or by clicking on the tempo eld in the transport section, and using the insert tempo change
at cursor option (Fig. 6.2.2) in the tempo properties to insert a new change at the current position of
the play-head cursor.
Note that each tempo change on the tempo curve has a third node located between the two ends of
the tempo range. This handle can be used to adjust the tempo curve between this tempo change and
the next. This allows you to create smooth tempo ramps.
You can also access the properties by clicking on a point on the tempo curve in the global track. Be
careful to click on a node, as the curve itself will display another set of properties (Fig. 6.6.3).
You will also nd the following options in the tempo properties:
Time: You can use this eld to view, or adjust the location of the selected tempo change.
BPM: This eld allows you to view or change the tempo.
Curve: This option controls the rate at which the tempo will change. A value of zero will create an
abrupt tempo change at the tempo change point. A value of one will create an abrupt change at the
next tempo point. Values in between these points will create tempo ramps of varying curvature between
this and the next tempo change.
Click here to tap out a tempo: This pad allows you to set a tempo by clicking the pad at the desired
speed.
Insert tempo change at cursor: This option will insert a new tempo change at the current position of
the play-head cursor.
Delete: This button displays a pop-up menu with the following options:
•
Delete this tempo setting: The current tempo change will be deleted.
Keyboard shortcut: DELETE or BACKSPACE.
•
Delete all tempo changes from the edit: All tempo change points will be deleted.
