Arduino Shield

Craft your own controllers


Complete Creative Control Freedom

MOD devices are entirely configurable and so should the peripherals be. Thus, the MOD Arduino Shield was conceived to help developers and makers create their own MOD controllers, custom-made to suit their unique performance requirements.

Easy To Use And Adapted To All Users

With little effort, anyone can assemble sensors and other electronic components, integrate them on an Arduino board and use it with any MOD device. Copy and paste some lines of code, solder components on the breadboard and easily design your controller of MOD effects.

Arduino Shield Adapt
Arduino Evolve

An Evolving Platform For New Controllers

You can create your 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 performatic capabilities while interacting with other musicians, dancers or actors on stage.

Open Hardware And Open Software

All the project files, not only the schematics and gerber, are open and available in our Github. We are using KiCad for developing our boards and cases schematics. All the components are listed in the bill of materials with links to the general suppliers. We also developed an Arduino Control Chain library that will do all the hard work so developers can easily implement their own cases.

Control Chain Devices

Control Chain is an open standard developed to connect external controllers to MOD audio processors such as footswitch extensions or expression pedals.

Compared to MIDI, Control Chain is much more powerful. Instead of using hard-coded values, it’s equipped with a device descriptor. Its assignment (or mapping) message contains the full information about the parameter, such as name, absolute value, range, and any other data. Accessing this information allows developers to create peripherals that can show the absolute parameter value on a display, use different LED colors to indicate a specific state, etc. It’s possible to daisy chain up to 4 control chain peripherals to your MOD Duo. Pretty neat, right?
