web application made by jen hill that lets users draw and sonify an Etch A Sketch drawing via MIDI protocol using chrome's Web MIDI API. try it at EtchASketch.FUN
for use with USB midi device:
connect midi controller && it should appear in the dropdown menu below the screen (you may need to refresh the page after plugging controller in)
click on a dial && turn a knob on yr MIDI controller to assign it to that dial ~~ reassign the dial to a new MIDI control knob by clicking again && turning a new knob
if no MIDI controller is available, user can draw pixels using the up/right/left/down arrow keys, even though this isn't nearly as much fun as MIDI
