What is QuNexus?

QuNexus is the next generation of portable keyboards.  The most playable, portable and powerful MIDI keyboard controller on the market. 25 pressure-sensitive silicone keys and LED illumination make QuNexus uniquely interactive and fun to play.

QuNexus Feels You

QuNexus' Smart Sensor keys detect finger pressure, tilt and velocity. Each key sends out a unique CC# as well as Polyphonic Aftertouch, and Channel Rotation allows for polyphonic pitch bends. Imagine pitch bend and modulation in every key.

Control Nexus- 

QuNexus fits perfectly in the center of your studio; a hub that integrates every synth protocol. Route controls for vintage CV analog gear, external MIDI hardware and audio production software.

Plug and Play

QuNexus is class compliant and works natively with any system that supports MIDI. Mac OS, Windows, Linux, iOS, and Android* with no software drivers required. You can also take control of analog gear via Control Voltage (CV) or 5-pin MIDI**.

Rugged on the Road

The QuNexus keys and buttons are made from a durable silicone composite, so don’t worry about the keys or buttons breaking when you throw QuNexus into your backpack or laptop bag.
