There isn't a way to generate system-level key or mouse events from within Pd. You'd have to use the platform native interfaces and probably write some code or use a user testing/scripting library.

I would go with the networking socket as that would work on both Windows and Linux.

I want to control OBS Studio with a MIDI device.
OBS Studio does not presently support MIDI directly.

I want to communicate to my MIDI controller with Pd.
I want to translate MIDI note-on/off messages into keystrokes
and pass those on to OBS.

Can I emulate "midikey2key" in Pd?

I guess I could also use obs-websocket

Thanks for your ideas :)
