low-profile hexagon keyboards.

getting started

Connect the 0x33.board to a computer using a USB-C cable (or a USB-A to USB-C). After a moment, the 0x33.board should turn on (the mode indicator, OLED screen, and some keys should light up). Once the board is turned on, you should find a new device in any software that uses the MIDI protocol.

basic operation

In the base mode, you can press any of the keys in the main 4x12 grid to play a note. Use the navigation keys / in the top right to move up or down an octave at a time.

By default, some keys will be highlighted in one of two colors, while the rest only light up when pressed. Pressed keys will light up and slowly fade back to their normal state.

While keys are pressed, the notes they correspond to are shown on the bottom row of the OLED screen and sent out via MIDI. To change which MIDI channels are used (amongst other things), press and immediately release the menu key to access the settings + profiles screen.

changing the highlighted scale

All the lit-up keys are part of the highlighted scale that is indicated on the top row of the OLED screen. In the default RGB mode scale, all the notes that are part of the selected musical scale are lit up, while the other keys are dark. The notes of the root octave are highlighted in color different from the notes of the octaves above and below to make it easier to understand the shape of the scale.

To change the root note of the scale (shift the pattern), press and hold the menu key. With the menu key still held, press any key in the main grid to set it as the root note of the scale.

To change the type of scale (major, minor, …) press and hold the menu key and use the navigation keys / to cycle through scale types.
