Double-O-Seven MIDI Commander Kit

According to Retrokits' project description (which takes the form of a very 007-esque plain text file), the RK-007 is "a gizmo made of low-cost parts with the aim to hack into your MIDI setup James Bond style.” The device features a subtle retro feel, with a boxy 3D-printed enclosure and a keypad/knob interface that wouldn’t look to out-of place in the early 1980s.

The RK-007 connects to other MIDI devices via USB, and also outputs MIDI commands via its serial bus, allowing you to add a ‘real’ MIDI port as needed. Its mostly numeric keypad interface is used in four modes, selected via the A-D keys. A allows for a program change, while B turns a note on and off; C selects the MIDI channel if you need to output to more than one gadget, and D modifies how the dial input is mapped. Numbers are first typed into the keypad, then entered or set with the # key and cancelled using *. If no numeric command is entered, # sends out a note panic command to clear things out on the MIDI channels and * toggles the MIDI start/stop messages.

The unit uses an Arduino Pro Micro for overall control, with visual output via a small OLED screen. You can see a demo of the RK-007 in the video below, and files to make your own are available here.
