I just released PKMidiCron 1.0 which will execute scripts, open files, and run custom python scripts with custom UIs. It also contains a decent midi simulator that is very useful for making midi mappings in Live. You can download it here:

I created this to remote-control my headless Ableton Live pedalboard, and use it almost every day. More here:

Please donate if you think it is useful and wish for others to be able to use it as well!
