The seventh annual Guthman Musical Instrument Competition finals were held Friday night in front of a packed house. Nine finalists, from all over the world, competed for $10,000 in prizes. They were:

• 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.
