QuNexus is a powerful MPE keyboard controller and three track arpeggiator/step sequencer. Its 25 touch-sensitive keys detect velocity, polyphonic aftertouch, and per-key tilt, giving you unprecedented control and musical expression. Each of the three arpeggiator/sequencer tracks can be programmed with up to 32 steps, 10 selectable arpeggiator patterns, and can be independently assigned to USB, MIDI, and Eurorack outputs. Blue and white LEDs illuminate the keys during arpeggiations, step sequences, and playback.

QuNexus can control MIDI hardware using the included MIDI Out cable or our optional MIDI Expander (sold separately). You can connect to modular synthesizers via the gate, three CV outputs, and two CV inputs, all of which can be assigned using the QuNexus editor which is compatible with Windows and MacOS.

We've re-imagined QuNexus as the center of your jam table. It's the first MPE capable keyboard controller with an onboard arpeggiator and sequencer, and with three tracks you can now easily switch between multiple synths, lay down different parts, and improvise on the fly. We've taken everything we learned from our flagship K-Board Pro 4 and rewritten the QuNexus key algorithm; the slides are instant, pressure is responsive, and switching between standard and MPE mode is as simple as recalling a preset. And, if you already own a QuNexus, all of these features are yours with a simple firmware update.
