Input: QuNexus receives data from the 2 CV inputs and converts them to MIDI messages:
• CV1 - CC#112
• CV2 - CC#113
This data is sent on Channel 2 to USB Port 3 and the MIDI Expander�

Make sure to establish a ground connection between your synth and the QuNexus before patching
the QuNexus CV inputs, otherwise you might observe strange behavior (interference in the QuNexus
key scanning)� The easiest way to do this is to patch any of the QuNexus Gate or CV outputs to your
synth�
!! Warning !!: The QuNexus CV inputs can only accept signals from 0 to 5 volts! Patching signals outside of this range
will cause the signal to be clipped, and negative signals will interfere with the QuNexus key scanning. While this should
not damage the QuNexus, it could potentially modify your preset settings, causing unexpected behavior. If this has
happened to you, we recommend re-loading the factory default presets using the QuNexus editor.

The function buttons on the left side of the QuNexus are used to select presets and change the playing
behavior of the keyboard� This chapter explores the use of each button: OCT +/-, BEND, SHIFT/PRESET,
HOLD A, VELO B, PRES C, and TILT D�

There are 2 triangular “OCT” buttons that increment or decrement the keyboard octave (in Keyboard
Layer only). When the QuNexus is first plugged in, both the OCT + and - buttons are lit up and the
keyboard has a range of C2 (note 48) to C4 (note 72)� QuNexus treats C3 as note 60 (Middle C)�
The OCT +/- buttons increment and decrement the QuNexus keyboard by one octave� The QuNexus
has a total range of 7 octaves (C0 - C7)�
The LEDs of the OCT +/- buttons indicate which octave you are in� When both LEDs are solid, you know
that you are in the original octave (with a base note of C2�) If the green Oct + button is pressed, the LED
will begin to flash, indicating that the QuNexus keyboard has been raised one octave. The LED will flash
faster as you continue to raise the keyboard by octaves� The same LED behavior applies in the opposite
direction for the OCT - button�

The BEND Pad is found in the bottom left corner of the QuNexus� It acts similarly to a pitch bend wheel�
When playing the keyboard, pressing the Bend Pad will send MIDI Pitch Bend data to bend the pitch of
the note� Shift pressure on the Bend Pad from side to side to bend up and down� Press the Bend Pad left
and right to bend the pitch up and down�
