Can I control Ableton Link’s BPM via hardware?

When hardware such as a DJ controller is connected, you can't change the BPM of Ableton Link using the TEMPO slider.

To control the BPM via hardware, you have to control the BPM on the Ableton Link subscreen (*1).

To do this, MIDI mapping is needed for the encoder or the button you want to use.

*1 While Ableton Link is turned on, you can right-click the [LINK] button in the global section and choose to show or hide the Ableton Link subscreen.
