Tempo is a floating point parameter with values denoting beats-per-minute (BPM). Synfire supports continuous tempo changes.

Tempo Tap-in Feature

Using the Parameter Inspector, you can tap ¼ notes on your external MIDI keyboard. Press the Tap-In button and start tapping until the tempo value stabilizes. Finish by clicking the button again.

Tip: With File > Convert > Scale Tempo you can globally double or halve the tempo of an arrangement. All phrases are then automatically stretched or compressed to reflect the change.


The parameter is Global and thus influences all instruments in the container.

Using the fader (slider) on the Parameter Inspector sets a particular value for the entire duration of the container (constant). If you want to continuously automate this parameter, you need to draw values in the Parameter View.


Drop a Container or Snippet on this outlet to extract the parameter.

Instead of drag and drop, you can also use copy and paste.
