You can create your own enhanced footswitches and expression pedals. You can create powerful adaptors. You can control your effects when moving your instrument, conceive sound installations or expand your performative capabilities while interacting with other musicians, dancers or actors on stage. We already have published projects for controllers using accelerometers, distance or light sensors but imagine using heart-rate or brainwave monitor sensors. 

There are no limits to what you can do!



  • Compatible with most Arduino platforms

  • Open source library available online at GitHub
  • Open hardware project
  • RS-485 (TIA/EIA-485) Standard - Full duplex
  • 2 RJ45 connectors
  • Power over Ethernet cable
  • Project created using KiCad EDA


Control Chain Devices

Control Chain is an open standard, including hardware, communication protocol, cables and connectors, developed to connect external controllers to the MOD. For example, footswitch extensions, expression pedals and so on.
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. Pretty neat, right?

And remember: you can daisy chain up to 4 Control Chain peripherals to your MOD Duo.
