Madrona Labs has put together a controller called the “Soundplane A”, made out of beautiful solid walnut. The idea is that it’s supposed to offer an organic feel, and high sensitivity that you might get out of an organic instrument.
The wooden surface is touch-sensitive, so can detect how hard you are pressing on the surface, and can act as a 150-note controller, or a fully continuous surface.
The video above shows it being used in a bit of an experimental piece. Very, very cool.
