bemini keymap

To switch between Player One (turntable on left) and Player Two (turntable on right) orientations, tap BOTH of the middle two upper (black) keys simultaneously while holding down all three edge buttons.

To switch between gameplay modes, tap one of the lower (white) keys while holding down all three edge buttons.

In Player One mode, the white keys are mapped to the following modes:
9 Key / Standard / Inverted / BMS / Keyboard

In Player Two mode, the white keys are mapped to the following modes:
Standard / Inverted / BMS / Keyboard / 9 Key

When playing in seven-key layouts, it is recommended to remove the two keys closest to the turntable (K01/K02).

Bemini uses QMK Firmware. If you wish to modify its button mapping, you can create and flash your own keymap. More information can be found here.

Bemini ships with a firmware which identifies itself over USB as an official Konami Beatmania IIDX controller, so it should work natively with most official Beatmania games. If you compile your own firmware using QMK, you will need to switch the default VID/PID in Bemini's "config.h" file to Konami's VID/PID (0x1CCF/0x8048) in order to enable this functionality.

Full default key mappings for each gameplay mode are provided below.
