You could also just use it as a voice interface, not touching the keyboard and just say "Compute, add reverb to my chords" "Computer, switch 808 drums out with 909 drums but keep the pattern and effects"

Which reverb and at what levels? It's way, way faster to hot swamp for previewing and getting the sound at what levels. Same with drums, I believe there are about 10 different kits per each of the 909 and 808 flavors in the factory tool kit. Typing out claude commands to do this kinda thing would be way slower than actually doing it. I'm not opposed to LLMs having control of the ableton interface, but adding and tweaking devices is going to be glacially slower via an LLM.
