About tempo changes and tempo automation of audio tracks
The built-in Stretch function in the Audio Track devices allows you to change the tempo of the song without affecting
the pitch of the recordings on the audio tracks. This is great if you want to adjust the tempo after you have recorded
your audio tracks. In Record, the Stretch is enabled by default for all audio clips.
There are two selectable Stretch algorithms which are suitable when playing back different types of audio material:
the “Melody” Stretch type is best suited for sources sounding one note at a time e.g. solo vocals, and the “Allround”
Stretch type is best suited for all other types of audio material.
D Select stretch type by clicking the Stretch Type radio buttons on the Audio Track device in the Rack.

Stretch preview vs. high quality stretch
Stretch is always made in two parallel steps: a real-time “preview” stretch so that you can instantly hear the result of
your tempo changes, and a high quality stretch “in the background” to further improve the sonic results. As soon as
high quality stretch is in progress, the “Calc” indicator on the Transport Panel shows a progress bar:
The CALC progress bar appears when Record performs high quality stretching of audio
Since the high quality stretch is performed in the background, you can still continue to work with your song without
any interruption. When the high quality stretch is finished, the “Calc” indicator goes out and the high quality audio au-
tomatically replaces the “preview” audio.
About disabling Stretch for audio clips
In some situations, you might want to exclude audio clips from tempo automation. For example, if you have recorded
dialogue or sound effects that shouldn't adapt to tempo changes. In such situations, you can select the audio clip(s)
you want to exclude from the tempo changes and select “Disable Stretch” from the Edit menu or clip context menu.
Automating time signature
Time signature automation events can only be manually drawn with the Pencil tool - not recorded like tempo automa-
tion, parameter automation or performance controller automation. A single time signature automation clip can only
contain a single time signature value. In practice this means that each time signature automation clip can only contain
one time signature automation “event”. All time signature changes in the song will require a unique clip.
1. Set the desired time signature in the Signature display on the Transport Panel.
This will be the Static Value, i.e. the time signature of the song wherever there is no clip present on the time sig-
nature automation lane.
2. Hold down [Alt](Win) or [Option](Mac) and click in the Signature display on the Transport Panel.
This will select the Transport track and create a time signature automation lane in one go. The Signature display
will also be displayed with a green border, indicating that the time signature has been automated.
q It is generally a good idea to activate Snap (see “Snap”) and have the Snap value set to “Bar” when drawing
clips.
