OpenDeck MIDI Platform
OpenDeck is a platform suited both for prototyping and developing custom MIDI controllers with easy to use web configurator. Platform uses class-compliant USB MIDI which makes it compatible with any MIDI software on any OS. Main part of the platform is board on which various components used to build a MIDI controller can be connected. The platform also supports DMX output so it can be used as DMX interface through
usbserial plugin in Open Lighting Architecture.
The following components are supported:
- LEDs (single color or RGB)
- FSRs (force-sensitive resistors)
- LCD/OLED displays
- Touchscreen displays (Nextion and Viewtech/Stone)
OpenDeck supports sending of both 7-bit and 14-bit Non-Registered Part Numbers (NRPN), latching messages on buttons, various encoding modes for quadrature encoders, LED control using MIDI In, configurable MIDI channels for each component individually etc. Full list of supported features can be found here.

Source code for OpenDeck web configurator is located in OpenDeckUI repository. It's written by wyrd-code. Web configurator can run in any browser which supports WebMIDI specification (Chromium based browsers only). Utility needs access to MIDI devices so that it can communicate with OpenDeck boards. All communication is done with custom SysEx protocol explained in detail in Wiki section.
Latest stable version of the UI is always available on this link.
OpenDeck firmware is compatible with official OpenDeck board, as well as various other boards:
- Arduino Mega2560
- Mux Shield v2 with Arduino Mega2560
- Teensy++ 2.0
- STM32F4 Discovery
- STM32F401 Black Pill
- STM32F411 Black Pill
Support for custom boards can be easily added using YAML descriptors.
Available on dedicated Wiki section.
