Bemini is currently being redesigned to use a new microcontroller. These new models will be available for sale soon. Please subscribe to the newsletter for updates.
Bemini ships internationally via USPS, UPS, or DHL Express.
Bemini is a low-profile mechanical keyboard controller for playing staggered-key rhythm games.
Featuring plug-and-play support for all your favorite rhythm games, including native analog control modes for Beatmania IIDX, Lunatic Rave 2 and more, as well as a full keyboard mapping (including the turntable) for all-digital control. 5-key, 7-key and even 9-key games are all supported right out of the box. Info about Bemini's default keymap can be found here.
Bemini was designed to be as portable as possible without sacrificing functionality. Now measuring only 220x70mm and weighing less than 100g, Bemini is easy to take with you just about anywhere.
With innovative low-profile Bourns rotary encoders, Bemini's analog turntable fits perfectly into the board's compact form, while still retaining all the sensitivity required for high-level play. Bemini also sports linear, low-profile Choc mechanical keys, allowing for fast, smooth and consistent presses with minimal pre-travel.
For those that prefer the turntable on the right, Bemini can easily swap between Player 1 and Player 2 layouts, with no tools or soldering required. Simply remove the staggered keys, replace them in the opposite slots, and rotate the controller 180 degrees.
Not a fan of turntable controls? With Mill-Max PCB sockets, even the turntable is swappable. For players who are used to playing with keyboards, or simply prefer the feel of a toggle switch instead of a turntable, the turntable can be easily removed or replaced with an (included) extra keyswitch. All control modes natively support this keyswitch. Please note that the encoder's support legs are now soldered in place by default for stability. All hardware required to support the hot-swap encoder and keyswitch is still included. If you wish for your encoder's support legs not to be soldered in place, please email us at email@example.com before your order ships.
With full n-key rollover and 1000Hz polling enabled by default, Bemini recognizes your inputs down to the millisecond, allowing for maximum precision in high-speed rhythm games.
Using a high quality through-hole USB-C port, there's no risk of inserting the connector upside-down, or breaking off a fragile surface-mount port.
Don't like the included keyswitches, keycaps, or even the encoder? No problem. Bemini is built with Kailh Hot-Swap Sockets for easy switch replacement with no tools or soldering required. Bemini is compatible with any Kailh Choc V1 or Choc-style keyswitches, as well as most standard three-pin rotary encoders including Alps EC12.
Powered by QMK Firmware, Bemini needs no third-party drivers and is recognized automatically by nearly all modern computers and mobile devices. Want to dial in the sensitivity, switch some buttons around, or even remap the entire board? Do it with QMK! It's open-source software.
Bemini ships with Kailh Choc Red linear switches (50gf), premium MBK PBT keycaps, and Bourns PES12 low-profile rotary encoders. Includes a 3D-printed PLA turntable.
