Other Lisp music related things include Incudine, Slippery Chicken, the Snd editor, MozLib (CL stuff for Max).
There have been several Scheme-like live coding systems that have become popular and faded away over the years. https://tidalcycles.org and its web-based friend https://strudel.cc are Haskell-like and were also getting some good attention a while go.
Either way, going to give this a go!
So when I read something like
> you can run Scheme (lisp) code directly in Ableton through my Scheme for Max project in Max for Live
Well ... sometimes the universe decides to make your decision really really easy.
If your budget constrains you to Garage Band -> Logic or Ableton Lite -> Standard, you will get more with the upgrade to Logic, especially if you rely on the instruments/presets that come with the DAW rather than 3rd party plugins. Note that you can't use the Scheme integration unless you buy Ableton Live Suite, which costs considerably more than Logic or Standard.
S4M is an open source extension to Max that allows you to run the s7 Scheme interpreter in a Max object, similar to the JS object in Max. Advantages over JS are that in can run in the high priority scheduler thread, enabling accurate timing, it has direct access to the file system from Scheme code, and allows you to make Scheme s-expressions directly in Max messages. It is also a very nice way to control the Live API, as the live API works on lists of symbols.

I'm planning another major release in the next few months as part of my PhD work.
