OpenDeck MIDI Platform
OpenDeck is a platform suited both for prototyping and developing custom MIDI controllers. 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. OpenDeck supports the following components:
- LEDs (single color or RGB)
- FSRs (force-sensitive resistors)
- LCD/OLED displays (Arduino Mega and Teensy++ 2.0 only)
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, daisy-chaining of boards etc. Full list of supported features can be found here.
OpenDeck firmware is compatible with official OpenDeck board, as well as various other boards:
- Arduino Uno
- Arduino Leonardo
- Arduino Pro Micro
- Arduino Mega2560
- Teensy++ 2.0
This repository also contains source code for OpenDeck Web configuration utility written using Angular framework by other developer. Web utility can run in any browser which supports WebMIDI specification (currently Google Chrome and Opera). 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.
UI is hosted in this repository and can be run via this link.
Important: UI is compatible only with latest available OpenDeck firmware. If older firmware is used, UI tends to crash when it tries to request parameters which aren't available in older firmwares.
File containing core app logic core.min.js was obsfucated and original source code was lost. Later, un-obsfucator was run on that file, however many variables and function names remain cryptic.
As I don't do any Web development I won't be adding any new features to the app. If you, however, want to contribute to it I would be more than happy to accept any improvements, new features or fixes.
