A Python / OpenCV plugin that adds aftertouch/wind control capabilities to any standard MIDI keyboard. Only requires an external webcam and a simple 4-note initial setup.
Good demos would be for playing a stringed instrument (guitar/violin) and … adding some extra soul to a Moog piano or something.

SoundFonts are like external libraries to generate sounds… hence the name! Most seem to be free.
