About
Control Chain is an open standard developed by MOD Devices that defines communication protocol, electrical specification, cables and connectors. It's used to interconnect external controllers (a.k.a peripheral devices) as expression pedals and foot-switches extension to MOD devices, for example the MOD Duo.
Comparing to MIDI, Control Chain is way more powerful. For example, instead of using hard-coded values as MIDI does, Control Chain has what is called device descriptor and its assignment (or mapping) message contains the full information about the parameter being assigned, such as parameter name, absolute value, range and any other data. Having all that information on the device side allows developers to create powerful peripherals that can, for example, show the absolute parameter value on a display, use different LED colors to indicate a specific state, etc.
The Control Chain devices are connected to the MOD using a regular Ethernet patch cable and they have two connectors, what allows a next external controller to be connected, creating then a chain. The MOD will provide power supply to the controller via the patch cable.
How to use Control Chain devices
The external controllers are connected using an Ethernet patch cable coming from the MOD Control Chain port to the Main port of the controller. To connect the next controller the cable should connect the Next port of the previous controller to the Main port of the next controller.
Once the controller is connected it will be automatically detected and ready to use. The actuators of each Control Chain device will show up as option to be mapped in the plugin configuration screen. See accessing plugin configuration screen for details.
To see a list with all connected Control Chain devices click on the Control Chain icon on the bottom-right of the screen.
How to upgrade Control Chain devices
Once a new firmware of a Control Chain device be available, the Web interface will warn you. To proceed with the upgrading click on Download button to download the latest firmware and then follow the instructions on the screen that is also replicated here.
Upgrading the Footswitch Extension device (FootEx)
- Disconnect the FootEx device from the Control Chain port
- Hold down the footswitch #1 on the FootEx device
- While the footswitch is depressed, connect the FootEx to the MOD via USB cable
- Wait for the "update completed" message
- Disconnect the FootEx from the USB port
- Connect it to the Control Chain port once again
Note: The upgrade should only take a few seconds.
