Keith McMillen QuNexus RED MPE MIDI-CV Mini Keyboard Controller

Quality and Flexibility - The Keith McMillen QuNexus RED MPE MIDI-CV Mini Keyboard Controller

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.
