New Musical Instrument Made With Thumb Sized Joysticks And #RaspberryPi #piday @Raspberry_Pi

Dave Sharple creates a whole new musical instrument called Joytone, a synthesizer made with thumb sized joysticks, a hexagonal grid, and Raspberry Pi

We wanted to invent an entirely new electronic musical instrument, and there were two things we wanted to focus on in the design of the interface. The first is that we wanted to improve upon the physical design of musical instruments. Most acoustic instruments are designed around physical phenomena that make sound rather than convenience for the user (violins are smaller than cellos because shorter strings make higher notes). This instrument uses a hexagonally isomorphic layout, which means that the notes are distributed on a hexagonal grid, and they all have the same physical size and shape. They also have the same musical relationships to each other – if you move to the right by one thumbstick, that corresponds to going up a perfect fourth musically, and this is true no matter where you start on the grid. This means that musical structures like a major chord or a minor scale are always the same shape, no matter which note you start on, which is pretty rad. The second thing we wanted to focus on was making the instrument really expressive. Lots of synthesizers only measure how hard you strike the key and other timbre controls are available on knobs that you have to remove your hands from the keyboard to use. We’re using little thumbsticks, which give you two dimensions of analog control in a familiar physical interface.
