Editing tempo and signature
The Time Warp tool (Cubase only)
Let’s say you need to match another cue to another position later on in the video. If
you simply repeat this procedure, you will find that the first cue gets out of sync –
since you are still changing the first (and only) tempo event on the tempo track!
You need to create a “lock point” – a tempo event at the first cue position:
10.Press [Shift] and click with the Time Warp tool in the event display at the cue
position.
In our case, this is bar 33.
A tempo event (with the same value as the first one) is added at that position.
11.Now match the second musical cue to the correct video position by dragging the
musical position to the desired time position as before.
The new tempo event is edited – the first tempo event is unaffected and the
original cue is still matched.
• If you know you are going to match several cues this way, make it a habit to press
[Shift] each time you use the Time Warp tool to match positions.
This adds a new tempo event – that way, you do not have to add tempo events
afterwards as described above.
About snapping
If Snap is activated in the Project window and “Events” is selected on the Snap Type
pop-up menu, the Time Warp tool will be magnetic to events when you drag the
tempo grid. This makes it easier to snap a tempo position to a marker, the start or end
of an audio event, etc.
Using the Time Warp tool in an audio editor
Using the Time Warp tool in the Sample Editor or Audio Part Editor is different from
using it in the Project window, in the following ways:
• When you use the Time Warp tool, a tempo event is automatically inserted at the
beginning of the edited event or part. This tempo event will be adjusted when you
warp the tempo grid with the tool.
This means that material before the edited events will not be affected.
• Only the default mode for the Time Warp tool is available.
This means that when you use the tool, the edited track is temporarily switched to
linear time base.
Making a tempo map for a “free” recording
The following example shows how to use the Time Warp tool in the Sample Editor to
create a tempo map matching freely recorded music. Let’s say you have recorded a
drummer, playing without a metronome – this typically means the tempo varies ever so
slightly. To be able to add more material and easily rearrange the recorded audio, you
want the tempo in Cubase to match the recorded drum track:
1. If necessary, move the recorded event.
Move it so that the first downbeat (“one”) happens at the start of the bar – zoom in
if needed.
2. Open the drum recording in the Sample Editor and make sure Hitpoint mode is not
selected.
The Time Warp tool cannot be used in Hitpoint mode. However, if you have
calculated hitpoints already, these will be visible when the Time Warp tool is
selected (see below).
3. Set the zoom so that you can see the individual drum hits clearly.
To achieve this type of “visual” beat matching, it is important to have a fairly clean
recording, such as the drum track in this example.
