Stringtrees is a New Interface for Musical Expression, and part of the ongoing research of Michael Gurevich. I specifically developed the front panel interface, laser cut plectrum holders, rotor lock mechanism, and rotation speed sensing (as pictured above). For more information on the project see the page on Michael Gurevich's website, or the NIME paper.
