Just diving into this, and find myself giggling like a kid at some of the things it can do. If you ever wanted to do something very specific that isn’t a canned feature in Live, chances are you can do it with this.
Tiny example of something I occasionally need to do: to play all scenes in order, create a new scene at the top. Place a clip in this scene on a new midi channel, and make this clip the duration you want to cycle through the scenes, and name the clip
 (LSEQ) SCENE >. This trigger the “next scene” action on every clip loop. Remove the stop button from this channel on all subsequent scenes, and play the top scene.
This only scratches the surface. It makes Live almost completely automatable. Also, I think something about the terse mini-language make me feel like I’m programming a mainframe.
