Jordan Rudess plays the Qu Nexus.

“QuNexus is a vividly illuminated keyboard that is both fun for beginners and a must have for modern musicians.”

QuNexus is a controller that everyone can have fun with. 25 vividly illuminated, touch-sensitive keys invite the beginner to explore, and provide valuable performance feedback for the professional.

Smart Sensor keys detect pressure, location, and velocity giving you unprecedented musical control.

Great for beginners and educators

Together with popular software apps, beginners can learn to play quickly and easily with QuNexus’ game-like blue and white glowing keys, creating a fun and interactive learning experience. Now anyone can play the piano.

Pro functionality

QuNexus is the first keyboard controller to unite four generations of synthesis: MIDI, Control Voltage, OSC and USB.

“Though unconventional, QuNexus’ sensor keys are faster and more accurate than my other keyboard controllers” Lauren Urroz (Keyboardist-DJ-Producer)

QuNexus is fully designed and prototyped. We are reaching out to you on Kickstarter to help us raise the funds for tooling and production.

Last year we successfully funded QuNeo on Kickstarter, raising more than $165,000 on our way to becoming the most funded music technology project in Kickstarter history at the time. In a poll taken after our project fulfillment, 94% of our backers said they would participate in another KMI Kickstarter project. Since the conclusion of our project QuNeo has continued its success, and we are very excited to launch our newest project, QuNexus.
