Dani Sanz was showing off his uber cool way Draw It Yourself MIDI controller using conductive ink to create push button surfaces at the Sonar 2014 festival, Barcelona. And, as you'll see from the videos the immediacy of altering your MIDI interface is mind-blowingly simple. If nothing else, this is a great way to prototype a hardware controller/instrument project.
Watch Draw It Yourself MIDI Controller in action:
Here's a video showing “Draw It Yourself” in multi-track mode:
In Dani Sanz' own words: "'Draw It Yourself' is a MIDI controller based on Arduino and capacitive sensing. It can be used as any kind of controller: you just have to draw the buttons on a paper using conductive ink, connect the buttons to the pins of the box, and you can play as in any other MIDI controller. The capacitive sensor detects the a change when a finger is touching the ink."
