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 usually monitors output 1 and 2, although it can also be set up to monitor the inputs directly through the device menu. It is also 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!

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 Paging 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.

LED Audio meters

The LED colors represent the following input levels:

• Off: below -30dB
• Green: between -30dB and -12dB
• Yellow: between -12dB and -3dB
• Red: above -3dB
• Blinking strong red: 0dB (CLIPPING!)

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.

TODO -> add screenshots from the LCD displays and explain what each part of the screen represent

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.

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

IMAGE: illustration explaining Duo X pages

Duo X allows you to switch between 3 pages of settings. This means that the 8 knobs and 4 buttons are actually 24 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.

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://modduo.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!
