The QuNexus Smart Sensor Keyboard Controller from Keith McMillen Instruments is a 25-key USB MIDI controller that features versatile parameter mapping as well as OSC and CV/Gate support. It is designed to provide expressive control of software instruments, MIDI sound modules and analog synths, for everyone from the beginner musician to seasoned professional.
The QuNexus' 25 "Smart Sensor" keys are designed to give the user comprehensive musical control. The controller detects both the tilt and the pressure being applied to each key as you play, both of which can be mapped to the MIDI parameter of your choosing. For example, key tilt can be mapped to the MIDI pitch bend parameter for applying vibrato to your performances by simply rocking the key back and forth. Also, each key is backlit by its own blue or white LED with 16 levels of brightness.
The QuNexus connects to your computer's USB port allowing you to control your software instruments as well as any MIDI sound modules that are connected to your MIDI interface. In addition, the QuNexus features CV/Gate (Control Voltage) support for controlling analog synth modules that may not have MIDI capability. It also supports the Open Sound Control (OSC) protocol for interfacing with hardware or computer-based instruments that utilize this newer, networking-based method of musical control.
