Overview
The wireframe images below expose the controls and inputs/outputs that the MOD Duo X has.
Device features
Inputs and outputs
Inputs jacks
The MOD Duo has two independent audio inputs, with configurable input gain for each input. You
can set up the input gain through the device menu.
Expression/CC Input
Output jacks
The MOD Duo has two independent audio outputs, with configurable output gain for each outut. You
can set up the output gain through the device menu.
Headphone/CC jack
The headphone output on the MOD Duo monitors output 1 and 2. It is possible to set the volume
level of the headphone output through the device menu.
Power jack
The MOD Duo comes with its own approved power supply which outputs 12V, 2A over a center-
positive barrel-type plug.
TODO: Add plug dimensions, minimum power requirements
The power consumption of the MOD Duo varies depending on the peripherals connected to the
device. For example: Hooking up a USB-hub to the USB-A port, and then hooking up multiple MIDI
controllers to the hub will change the power requirements. By using the provided power supply you
are sure that you will never run out of juice.
Control Chain port
TODO: explain use for CC, advantage over MIDI
NOTE: Please do NOT connect this port to a regular Ethernet port, it can damage your MOD Duo.
USB Host port
In the most common scenario, this port is used to hook up a single USB-MIDI device, such as a MIDI-
keyboard to control generator plugins.
Another common scenario is using this port to hook up a Bluetooth dongle for wireless connection to
your PC.
NOTE: The port can also be split up into multiple ports using a USB-hub for connecting multiple
USB devices to the MOD Duo.
USB computer port
This port is mostly used to connect the MOD Duo to your PC for setting it up. When executing a
manual system update, its use changes to a mass-storage device, so that you can copy the update-file
to the MOD Duo.
DIN-MIDI I/O
Finally, the MOD Duo also supports old-school DIN-MIDI devices, simply hook up your DIN-MIDI
device to the appropriate port on the back and enjoy!

snapshots of your current state on the fly. See the Instant Snapshots section below to learn how to
use them.
Pagination
The button on the center is the pagination button that allows you to switch between 3 different
pages holding different controls for all actuators. See the Switching Pages section below to learn
how to use it.
Displays
The MOD Duo X has two large (2.8") LCD displays. The displays normally give dynamic information
about the actions mapped to the device actuators, but they are also used for displaying the device
menu and tuner.
Each part of the display corresponds to one of the actuators. (See image on the right)
How each section of the screen maps to each actuator
Left Display
The top section of the left display shows the Current Pedalboard name.
The section just below it shows the control mapped to the left endless knob.
The four following sections represent the four knobs.
The bottom section represents the two left buttons. Notice that the background color changes to
identify the parameter status.
Right Display
The top section of the right display shows the Master Volume. The Master Volume can be adjusted
by pressing and holding the right endless knob. See more information in the Adjusting Volumes
section.
The rest of the sections represent each actuator in the same way as in the left display, but mapping
to the knobs and button on the right.
Dimensions
LED Audio meters
The LED colors represent the following input levels:
Off: below -30dB
■
Green: between -30dB and -12dB
■
Yellow: between -12dB and -3dB

Adjusting Volumes
Detail of the right display showing the Master Volume
To adjust the Master output volume, press and hold the right endless knob. This will turn this knob
into the master output volume control.
Press and hold it again to exit this mode.
The MOD Duo X also allows each input and output volume to be individually adjusted.
Please refer to the Inputs and Outputs Device Settings section in the wiki for more information on
that.
Tuning
The MOD Duo X has a built-in chromatic tuner that can be accessed by pressing and holding the
right knob for one second. Both inputs can be used as the tuner input, to select between them short
press the right knob. To exit the tuner press and hold the right knob for one second.
If you see a question mark on the tuner screen, it means the MOD Duo is not receiving any input or
the input levels are too low.
Please refer to the Tuner section in the Device Settings page for more information.
Playing
After you have powered on and adjusted the volumes of your MOD Duo X, it is ready for playtime.
The MOD Duo X comes with many pedalboards ready to be used. They are organized in banks and
can be accessed via SETTINGS menu.
Please refer to the Banks section on the Device Settings page for more information.
When you load a pedalboard, all plugin parameters will have the last saved state. You can save a
new state or restore the last saved state using the Settings > Current Pedalboard menu.
Instant Snapshots
While performing, you can create and load snapshots of your configuration on the fly. This will
save/restore all parameters of all knobs, encoders and buttons that are controlling plugin
parameters.
There are two Instant Snapshots buttons you can use. They are the most left and right buttons at the
top center part of the Duo X panel.
IMAGE: Details showing the position of the Instant snapshot buttons
Press and hold an Instant snapshot button for a second to save a new Snapshot. The button will
quickly blink and then the light will turn on. When the light is ON, it means there is an Instant
Snapshot saved and ready to be loaded. Quickly press the button to reset your device to the state of
the saved snapshot.
Switching pages
Note: The animation above does not show it in details, but Buttons and Endless knobs are
also paginated.
Duo X allows you to switch between 3 pages of settings. This means that the 8 knobs, 2 endless
knobs and 4 buttons are actually 24 knobs, 6 endless knobs and 12 buttons. When you address a
plugin parameter to a Duo X actuator, you can choose in which page you want to address the
parameter to.
IMAGE: screenshot: detail of the address interface in the GUI showing the 3 pages of actuators.
The pagination button is the central of the 3 top buttons in the Duo X panel. It's light indicate the
current selected page:
1st page: red
■
2nd page: yellow
■
3rd page: green
■
IMAGE: picture: detail of the pagination button
To change the page simply press the button.
True Bypass
MOD Duo X has a true bypass circuit for each pair of input/output. This allows you to physically
connect input 1 to output 1, and input 2 to output 2. The true bypass is enabled when the device is
off and it is automatically disabled after the current pedalboard is loaded.
You can enable or disable the true bypass via the GUI, or use a plugin and assign this control to any
actuator. See the Web GUI User Guide for more info.
You can also enable it via the Device Settings menu. Check Hardware bypass section on Device
Settings page for more info.

volumes and MIDI Settings, manage User profiles and more.
Editing
Accessing the graphical interface
The MOD Duo X has a built-in graphical user interface (GUI), which means you don’t need to
download any extra software in order to configure the device. To access the interface, you only need
a web browser, such as Chrome, Safari or Firefox.
Once you are connected to your device you will be able to build and share your pedalboards,
download new plugins, organize your banks for offline access and much more.
Please refer to the Web GUI User Guide to learn all about it.

Accessing via USB cable
The easiest way to access the GUI is through the USB cable. Simply connect the USB cable, which
you received along with your MOD Duo X, to your PC or Mac. The operating system should
recognize the MOD Duo X as a network device and configure it automatically. However, this process
may fail in certain Windows versions, if that is your case please check the troubleshooting page
After successfully connecting the MOD Duo X to your PC or Mac, open your favorite browser and
navigate to http://modduox.local (or http://192.168.51.1).
Accessing via Bluetooth
It is also possible to connect to your computer using a wireless Bluetooth connection. Check this
page to see how to do this!
