How do I implement red box paging?

0

I’d like to create a script that allows me to page through scenes 8 at a time in session mode using the existing red box for the Launchpad. The reason is because Ableton is slow and tedious when scrolling through scenes one at a time. For projects that have over 200+ scenes, this isn’t practical during a live performance. Jumping 8 scenes at a time would be a game-changer! I do not wish to overwrite the existing Launchpad behaviour, since I’ve been able to leverage that to good effect. As a compromise, I’m willing to map two buttons on my Launch Control XL to perform the paging (up: 9/104, down: 9/105). The CC values for the Launchpad up and down buttons are 1/91 and 1/92, respectively.

I’ve watched several video tutorials, browsed the forum, and played with Python and ChatGPT to get something working, but alas, no dice. What do I need to do to get this working?

Hi John,

Thank you for your quick reply. Unfortunately, this did not work. A message appeared in Ableton 11 saying: “There’s no active session box, so feedback cannot be sent.” The existing red box appears in Ableton since I have the Launchpad plugged in. This is the red box I’d like to control.

Here are the things that I tried:

  • I made sure to push updates to the folder, even deleted the folder, and your software recreated it.
  • I made sure to shut down and restart Ableton after each script deployment.
  • I added css movebox as a control surface and added the Launchpad as both an input and output.
  • I also tried the step above, but without the Launchpad as an input and output.

I can also confirm that the Launch Control XL is sending CC messages properly since both Ableton and your software light up accordingly.
