Control sc through hid keyboard

i want to control some sound things in sc with one hand from time to time while i am playing an instrument. i did/does work in pd with the hid-keyboard object. in sc i can’t really find anything in the documentation. HID class seems to have an empty space. i have set the proper permissions with an udev rule but now i am stuck. i am not an expert in sc…but want to learn hot get this going. some good tips welcome.
my first test configuration would be to play a major chord by pressing two keys f.e. “c”+“d” at the same time…

On a typing keyboard, as opposed to a midi keyboard?

jumping on, I’d like to know if there’s HID bindings to a PS4 controller.

Any thing here, maybe? Modality Toolkit [Supported Controllers]
