Tempo automation recording

In Reason it’s possible to record automation of the sequencer’s tempo. This means that a song can automatically change tempo whenever you like. You can record tempo automation events on the parameter automation lanes on the Transport track.

Recording tempo automation

Automating tempo is done much in the same way as with other parameter automation. You record the tempo changes by changing the Tempo value on the Transport Panel. When you later play back, audio clips will automatically be stretched to follow the tempo changes (unless you have disabled stretch for the clips - see “About disabling Stretch for audio clips”). Note clips and automation clips will always follow tempo changes.

To record tempo automation, do as follows:

1.	Set the desired song tempo in the Tempo display on the Transport Panel.

This will be your static value, i.e. the tempo of the song wherever there is no clip present on the tempo automation lane.

2.	Press [Alt](Win) or [Option](Mac) and click in the Tempo display on the Transport Panel.

This will both select the Transport track and create a Tempo automation lane at the same time. The Tempo display will also be marked with a border, indicating that the Tempo parameter has been automated.

3.	Start recording in the sequencer and record the tempo changes by changing the value in the Tempo display.

Click and drag up/down in either of the display segments to change tempo in BPM steps or 1/1000 BPM steps.

You can also manually draw Tempo automation events in the parameter automation clip, using the Pencil tool - see “Drawing tempo automation events”.
