Max4Live devices, Selected Track Control, Shortcut Buddy, TekktrackControl and TrackController for most things. Stability is variable!!
Focussing on using my midi controller and a custom script called Selected Track Control (just to be awkward). I've made a few changes to this script and in the process found a few limitations that make some things virtually impossible to implement for anyone outside ableton. So we're kinda stuck.
Learning the ones that are there. Seriously, there are more than 200!! I counted.
