This is an international competition to find the musical instruments of the future. The instruments produce nontraditional sounds and use technology to let us play in a new way. 

Twenty semi-finalists performed before judges Thursday and Friday. The judges narrowed the group to nine finalists. The finalists are (listed in the order they will perform):

• Push Pull - This instrument looks like an accordion but it combines inertial sensor data with sound input and digital synthesis. 
• Nomis - This instrument aims to make loop based music more expressive and transparent through gesture and light.
• Magentic Percussion Tower - This instrument combines aspects of kinetic sculpture, music box design, drum machine and interactive art. 
• Dulsitar - This instrument incorporates traits and design found in both the sitar and dulcimer.
• Cantor Digitalis - This instrument is an open-source real-time singing synthesizer using hand gestures, with the help of an accurate and intuitive interface based on a pen/touch tablet.
• D-Box - This new digital instrument is encased in a wooden cube and is designed to be repurposed and rewired by performs. This hacking lets a performer play it in unusual ways.
• Dualo Do-Touch - This instrument is a controller, synthesizer and a looper/sequencer that is based on a new layout of notes.
• Ndial - This instrument combines automated sampling and sequencing with manual controls to navigate sound worlds in unpredictable ways.
• The Sponge - This instrument is a a piece of foam equipped with sensors which can detect when it is squeezed, twisted or shaken.
