Editing tempo and signature
Tempo Detection (Cubase only)
Using the Time Warp tool in a MIDI editor
This is very similar to using the tool in an audio editor:
- When you use the Time Warp tool, a tempo event is automatically inserted at the
beginning of the edited part – this tempo event will be adjusted when you warp the
tempo grid with the tool. Material before the edited part will not be affected.
- Only the default mode for the Time Warp tool is available. So when you use the
tool, the edited MIDI track is temporarily switched to linear time base.
- The rulers in the MIDI editors can be set to “Time Linear” or “Bars+Beats Linear”
mode (see
“The ruler” on page 485) – the Time Warp tool requires Time Linear
mode. If necessary, the ruler mode will be switched when you select the Time
Warp tool.
- If Snap is activated on the toolbar in the MIDI editor, the tool will snap to the start
and end of MIDI notes when you drag the tempo grid.
Typically, you would use the Time Warp tool in a MIDI editor to match the Cubase
tempo to freely recorded MIDI material (much like the audio example above).
Tempo Detection (Cubase only)
Cubase offers a powerful tempo detection algorithm that can be used on any rhythmic
musical content, even if it has not been recorded to a metronome click and/or
contains tempo drift. This feature serves two main purposes:
Analyzing the tempo of freely recorded audio so that other (audio or MIDI) tracks
can follow this tempo.
Adjusting freely recorded audio to the project tempo, which can be fixed or variable.
Audio requirements
- The audio event has to be at least 7 seconds long.
- Musical Mode has to be deactivated for the clip.
- The track has to be set to linear time base (this happens automatically).
- The audio material needs to have discernible beats.
The Tempo Detection Panel
The Tempo Detection Panel contains the functions for analyzing the tempo of an audio
event. It is opened via the Project menu.
In the top section of the panel, the name of the selected audio event is shown. Below
the name, the Analyze button is located. Click this button to start the tempo detection
for an event.
The middle section contains several functions for correcting and fine-tuning the
detected tempo curve. These functions are described in the section
“Correcting and
fine-tuning the detected tempo map” on page 626.
