This list of Frequently Asked Questions will help answer common questions that new or prospective QuNexus owners may have. Browse through the questions below to find the answers you seek.
Connect QuNexus to MIDI hardware:
The image shows QuNexus connected to a hardware MIDI device via our MIDI Expander (sold separately):
All Factory Presets are set up to send MIDI out through the MIDI Expander so once everything is connected you should be able to play your MIDI Device.
Connect QuNexus to an iPad:
The image shows QuNexus connected to an iPad via USB. You will need the iPad Camera Connection Kit (sold by Apple). Attach the camera connector to the iPad and then use a USB A-to-Micro cable to connect the QuNexus micro port to the camera connector.
Open an iPad app that accepts MIDI and make sure your iPad’s volume is up.
There are a couple of different ways to connect QuNexus to a CV device:
There are 2 CV output ports on the left side of the QuNexus and 1 CV input port on the right side. Since the two output ports use stereo 1/8in connectors (TRS), they provide 4 outputs: a gate output and three 16-bit CV outputs. Output voltages range from 0 to 5V. The input port should be used with a TRRS connector to access both CV inputs and the 5V Power for an expression pedal. If you only need one input for an expression pedal, a regular stereo 1/8in connector should work just fine.
By default, QuNexus sends different data out the 4 CV outputs:
This data can come from the Keyboard, USB Port 3, or the MIDI Expander. By default MIDI must be received from Channel 2 if sending from USB Port 3 or the MIDI Expander.
By default, QuNexus receives data from the 2 CV inputs and converts them to MIDI messages:
By default this data is sent on Channel 2 to USB Port 3 and the MIDI Expander.
Much more information about using QuNexus with CV exists in the QuNexus Manual so be sure to take a look at the CV chapters there for more information.
There are four Preset slots on QuNexus. To select different presets tap the Shift / Preset button on the left side of the QuNexus.
The LEDs on the keyboard will swipe to indicate that you are in Preset Select Mode. Then one of the four lettered buttons will light up to indicate which Preset is currently selected (A, B, C, or D). Next tap one of the four buttons to choose a different Preset. Upon making a selection the LEDs on the keyboard will swipe again to indicate that you are leaving Preset Select Mode and entering the chosen preset.
Use the QuNexus Editor to Export the preset you wish to share. Go to the menu bar and click “File”. Then click Export Preset. Export Preset allows you to save a file containing the currently selected preset for safe keeping or sharing.
Send your preset file to your friend and have them use the QuNexus Editor to Import the preset you shared with them. Import Preset lets you select a previously exported preset and load it to the currently selected preset slot. Make sure your friend saves the preset after importing it.
If no update prompt appears, go to the QuNexus Menu and select “About QuNexus”. The window that appears will show the expected version numbers and the version numbers the QuNexus has. If the board’s firmware version does not match the editor version, use the “Update Firmware” option in the Hardware menu of the QuNexus Editor. A prompt to update will appear. Click ok to update firmware.
Don’t worry if your bootloader version is not the same. The bootloader does not have an effect on how the firmware performs or its compatibility with the editor. We will be implementing a way for users to update the bootloader as soon as possible.
The QuNexus uses a micro-USB connector. This is different from a mini-USB connector (and much more robust), so make sure you get the correct cable if you’re looking to purchase an extra cable or replacement. The cable must be at least USB 2.0 to work properly.
LEDs can be controlled by sending MIDI Notes through USB Port 1 to the QuNexus. Notes 48 (C2) - 72(C4) will control the keyboard LEDs. If you send notes outside of that range they will wrap around and still control the LEDs of the Keyboard. MIDI Input cannot currently control the Left Side Buttons. Channel 1 is used as the LED Input channel in our Factory Presets (with exception to Preset D, which uses Channel 9) but the Channel number is editable using the QuNexus Editor. See the LED Mode chapter of the QuNeuxs Manual for more information on how to edit the Channel number in the Editor.
If your QuNexus is not working with your music software it could be due to a number of things:
The most likely cause of this problem is a bad USB cable. Try using a different USB cable.
Use the QuNexus Editor to adjust the sensitivities for each preset.
The boxes above are for all keys and can be set differently for each preset. The first box, “Sensitivity”, is basically a multiplier for the sensitivity; if it’s set to 2, the keys will be twice as sensitive, if it’s set to .5 the keys will be half as sensitive.
The on and off thresholds are for changing the pressure value at which a note on or a note off will register. For Example: if On Thresh is set to 10, the Pad pressure has to reach a value of 10 before a note on is sent. If Off Thresh is set to to 5, the Pad pressure would have to be 5 or lower for a note off to register. Off Thresh cannot be set higher than the on threshold.
Tilt Sens. refers to how much wiggling you have to do to get the Tilt source to respond. By default Tilt requires an intentional pressure shift/tilt of your finger to engage it so that you don’t bend a note or adjust an effect by accident. You can adjust this feature with the Tilt Sensitivity feature here.
Yes! You can use as many QuNexus’ as you can power and connect to your computer.
If you want to edit the settings of multiple QuNexus’, then you’ll need to do that one at a time using the QuNexus Editor.
No, you do not need to use the QuNexus Editor to use your QuNexus. The QuNexus ships with 4 presets already on the board that you are welcome to use. You only need to use the QuNexus Editor if you want to modify the existing presets or create your own presets.
You likely just need to update your presets. Updating to new firmware will reload the Factory Presets. If you made custom presets they will need to be resent to the QuNexus.
The QuNexus is a class-compliant USB MIDI device, which means you will not need to install anything to use your QuNexus with a computer.
If your QuNexus is exhibiting this behavior, you likely have a bad USB cable. Replacing your cable will more than likely fix this issue.
Many DAWs and performance software tools like Ableton Live and Apple’s Logic have MIDI Mapping modes that will recognize MIDI data from a controller and map it to whatever you choose. Since the QuNexus can have multiple data sources for one control, it is often necessary to use the Controller Mapping Assistant (CoMA). CoMA mode allows quick mapping of each available data source one at a time, enabling rapid and efficient software/controller pairings.
To enter CoMA Mode:
Tap the Shift Button to exit CoMA Mode and go back to playing QuNexus normally.
CoMA will work differently depending on whether Channel Rotation is turned on. To check whether or not Channel Rotation is on after performing step 1 above, check to see if the Rotate key is lit up. If so, Channel Rotation is on.
For more information about CoMA Mode, see the QuNexus Manual. There you will find a full step-by-step guide for using CoMA Mode while Channel Rotation is off or on.
Live Edit Mode is mainly intended for making quick edits on the fly. In Live Edit Mode you can turn on and off Channel Rotation, change the MIDI output channel, transpose the keyboard, go into CoMA mode, turn Channel Pressure and Poly AfterTouch on and off, set the bend range, and send program change messages. It should be noted that these edits do not persist after changing presets or unplugging QuNexus. Any Live Edits will affect Keyboard Layer only (not Controller Layer).
To enter Live Edit Mode hold the Shift button for approximately 1 second until all the LEDs pulse on and then off. To exit just tap the Shift button again. For more information about Live Edit Mode, see the QuNexus Manual. There you will find a full step-by-step guide for using Live Edit Mode for each of the purposes listed above.
Channel Rotation is a feature that causes the order of keys pressed at one time to rotate through channels. For example, the first pressed key’s MIDI data from Keyboard Layer goes out Channel 1, the second pressed key’s data goes out Channel 2, the third pressed key’s data goes out Channel 3, etc. Release those keys and you will start over on Channel 1 next time you press a key.
This feature is useful for getting a different pitch bend, channel pressure, or poly aftertouch for each note as opposed to one for all notes.
The QuNexus Factory Preset C is set up to use Channel Rotation. To use this effectively in software or hardware, you must make sure the application/device is set to listen on All MIDI Channels. Applications often call this feature “Omni”, “All” or “Any”.
See the answer to the previous question, “What is Channel Rotation and why would I use it?”.
Keyboard Layer is a term used to describe the basic QuNexus Keyboard behavior. This includes the default notes that can be shifted using the Oct Buttons. It also includes anything else that is editable in the Editor’s Keyboard Tab like: pitch bend, channel pressure, poly aftertouch, etc.
Controller Layer is a term used to describe the extra MIDI data that can be assigned to send out on top of the MIDI data that Keyboard Layer sends out. This is needed if you wish to send out a second Note that is unaffected by the Oct buttons or if you wish to have separate Pressure and/or Tilt CCs per key. Controller Layer is editable using the Controller tab in the QuNexus Editor.
