On a recend trip to uganda I've seen someon controlling ableton with a usb computer keyboard as a foot controller. I like the Idea, it's cheap and replacable, perfect for a traveling setup!
But since my usb input is always taken by a midi controller I was wondering if it would be somehow possible to hook up an oldschool keyboard with a ps/2 connector somehow to the serial pins on the axoloti. Aparently it's possible on the arduino http://www.instructables.com/id/Connect-PS2-Keyboard-to-Arduino/ so I guess theoretically this could be adaptaed to axoloti?
