For people into this sort of thing, another option is using my foss Max extension, Scheme for Max, to script Live through the live API using Scheme. https://www.youtube.com/watch?v=j0sKBA-Pv2c&t=1s

The live object model is MUCH nicer to use in a lisp, as basically you do everything by making dynamic lists to represent what you want to access! There are examples in the Scheme for Max help file.

(Also, Scheme for Max can run in the scheduler thread, unlike JS in Max. Though of course calls to the Live API are deferred to the lower priority thread anyway)
