Editing tempo and signature
The Time Warp tool (Cubase only)
Viewing and adjusting tempo events
When you select the Time Warp tool, the ruler of the active window is shown in
brown. Existing tempo events are shown in the ruler as “flags” with the tempo values
displayed.
This helps you see what’s going on, but you can also use this for editing the tempo
track:
• If you press the create/erase modifier key (by default [Shift]) and click on a tempo
event in the ruler, it is deleted.
[Shift] is the default modifier for this – you can adjust this in the Preferences dialog
(Editing–Tool Modifiers page).
• You can click on a tempo event in the ruler and drag to move it.
This automatically edits the tempo value in the event so that elements to the right
keep their positions.
• If you press [Alt]/[Option] and move (or delete) a tempo event in the ruler, the
tempo value is not adjusted – this means elements to the right will be moved.
This is the default modifier key for this – you can adjust it in the Preferences dialog
(Editing–Tool Modifiers page).
Using the Time Warp tool in the Project window
In the Project window, there are two modes for the Time Warp tool. To select the
desired option, click on the Time Warp tool and click again to open a context menu.
The available options are:
• Warp Grid
This is the default mode. If you use it, all tracks are temporarily switched to linear
time base. This means that all tracks will keep their absolute time positions when
you adjust the tempo track.
• Warp Grid (musical events follow)
If you use this mode, no tracks are switched to linear time base. This means that all
tracks that are not set to linear time base will follow the changes you make to the
tempo track.
Matching a musical score to video
Here’s an example of how to use the Time Warp tool in “musical events follow” mode.
Let’s say you are creating the music for a film. You have a video track, an audio track
with a commentary and some audio and/or MIDI tracks with your music. Now you want
to match the position of a musical cue to a position in a video film. The musical cue is
located in bar 33. There are no tempo changes in the project (yet). Proceed as
follows:
1. Make sure tempo track mode is selected on the Transport panel.
2. Now you need to locate the position in the video. If you do not need very high
precision, you can simply locate it by looking at the thumbnails on the video track –
otherwise you can pinpoint the exact position and add a marker to the marker track
(to which you can snap later).
You can also make a note of the exact position and add an extra ruler track set to
show the timecode (Cubase only).
