It’s an extension for Ableton Live that lets you recall up to 500 scenes on dLive and Avantis consoles via MIDI. The concept is pretty straightforward: MIDI notes select groups of scenes (10 per note), and velocity determines the exact scene within that group. So with a single note + velocity value, you can directly trigger any scene.
Everything is designed to be quick to set up and reliable in a live environment, especially if you’re already working with dLive or Avantis.
It actually does use Program Change under the hood
The MIDI note + velocity mapping is just a more “musical” way to think about it inside Ableton.
Instead of dealing with PC numbers directly, you can trigger scenes in a way that fits naturally into clips and MIDI programming.
Glad to hear it might be useful — that’s exactly the kind of use case I had in mind (triggering scenes from a backing track rig at FOH or on stage).
