Add custom python code that generate MIDI signal, note or CC

Hello,

is it possible in Action for reactions to add custom python code (switch to custom coding) that generate MIDI signal, note or CC?
I tried, but do not have expiriece in pytoh, and did not get any results.

My idea for this is that for different conditions in Reaction to generate differnet MIDI notes/CC, and that MIDI notes/CC can be usted for example with BOEME MIDI creator or Autohotkey to trigger something else outside of Ableton (not for playing music, but for some functions).
