How far are we from being able to use a computer keypad to control axoloti?
In the raspberry pi times I used one to control a synth and it turned out to be a great solution.... I could play polyphonic and I used some keys as shift functions in order to multiply the functionality of the number keys.
Unlike most cheap Diy buttons, It's possible to do finger drumming in a keypad.
for what I see here: https://github.com/axoloti/axoloti/blob/master/firmware/STM32_USB_Host_Library/Class/HID/Inc/usbh_hid_usage.h
Axoloti might recognize a keypad (among many other things) but then, we just miss an "hid" object? If it's made in a generic way (like in puredata) just one hid object will allow to use keyboards, joysticks, trackpads / etc.
In the picture you can see my salvaged keypad (It was from the trash)
