Applies to Launchpad X
The Launchpad X is supported in Live 10.1.3 or later so will not function to its full potential in Live 9, but if you have an older version of Ableton you can use it as a generic/basic MIDI controller.
To do so please go the Link/MIDI preferences of Ableton and match the settings below, your operating system will affect how the ports appear:
You can then use the MIDI Map button in Ableton to map the controls of your Launchpad to the device/mixer of Ableton.
Features that are not possible without Abelton integration mainly include but are not limited to; Clip Launching, Record/Capture, Mixer control
Alternatively, you can install the included copy of Ableton Live 10 Lite for free for more advanced control.
