Here’s an example of controlling the Zynthian hands free. I find it far more accurate than pressing a button for quick sound changes. I also finally got my first 3D printer so I built the gesture sensor into a small little dongle that can work with any Zynthian. Next stage will be to design and print a new Zynthian case so that I can have the sensor and Zynthian all in one box.
Here’s a photo of the sensor in it’s case.
