## Overview

The Keith McMillen Instruments QuNexus RED is a cutting-edge 25-key USB MIDI keyboard controller designed for musicians and producers. It features polyphonic aftertouch, a 3-track step sequencer, and an arpeggiator, all housed in a sleek, durable ABS-Polycarbonate finish. With multiple connectivity options, including CV I/O and MIDI expanders, this controller is perfect for both studio and live performance settings.

## Description

QuNexus RED 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Small. Smart. Multifunctional.
*by M***S on September 30, 2022*

For me, the Qunexus is a great solution for my travels. Very stable, small and the design suits my taste. The only advance warning is that the menu goes in depth with key combinations, but that shouldn't deter you. At least you learn something, the manual sums it all up. I recommend buying the midi expander if you intend to use it with other hardware. The package includes a usb cable and a midi trs cable. Cheers.

### ⭐⭐⭐ Mushy inconsistent key presses
*by T***N on January 16, 2023*

The made headline for this product is it's portability and it's MPE capabilities, but it uses a PCB capacitive touch design where the sorta-rubber key material makes contact with the PCB itself and it registers pressure. I've found the pressure sensitivity to be wildly inaccurate and inconsistent. As much as I loved the portability, the actual key feel and aftertouch response is awful.

### ⭐ DO NOT BUY - product broke and CUSTOMER SUPPORT DOES NOT ANSWER
*by A***  on July 10, 2023*

The worst customer service I have ever experience with not even a reply. WHAT KIND OF BUSINESS CHARGES A RIDICULOUS AMOUNT FOR A KEYBOARD and then DOESN'T REPLY TO A SUPPORT COMPLAINT!I am never one to complain but it has been around a month with 4 complaints I have sent and asking for an update. Ridiculous.The product isn't all that great either and there are much better options out there for what this is. Absolutely ridiculous please do not buy from this company. They don't deserve our money.
