Tuna Knobs are a set of knob-based controls that can be attached to any capacitative touchscreen to add a whole new dimension to the digital music-making experience. The knobs essentially bring the sensation of touch-based feedback to music-making apps and software.
The setup begins with the attachment of a transparent acrylic base to the touchscreen of the device using a suction cup. The base is attached so as to align with virtual knobs displayed on-screen. This allows digital music composers to turn the knobs and see their physical movements translated into touch commands in the accompanying app.
Tuna Knobs are compatible with iOS, Android as well as Windows devices. The developers of Tuna Knobs have taken to Kickstarter to raise funds for further development and production of their nifty product.
