Unleash your creativity with the Denki Oto OMX-27, a versatile DIY hardware MIDI controller and sequencer that's tailor-made for musicians who love to customize their gear. This compact, robust unit is equipped with 27 RGB backlit mechanical key switches, offering both Cherry MX and Kailh Choc options to suit your tactile preference. The OMX-27 isn’t just about aesthetics; it's about function with flair.

Designed for those who appreciate the art of DIY, the OMX-27 kit comes with everything you need to craft your perfect MIDI controller. From an SMD-assembled PCB to a pre-soldered white OLED display, the kit is engineered for ease yet offers the depth of customization that seasoned builders crave.

With its USB-C connectivity and comprehensive I/O options, including USB-MIDI and hardware MIDI In/Out, the OMX-27 integrates effortlessly into any setup. The hardware also features CV pitch and gate outputs for those who desire a more analog experience. The five potentiometers and single encoder, adorned with Befaco-style micro knobs, provide tactile control over your soundscapes.

Dive into the world of soldering to truly make this device your own. The OMX-27 is more than a MIDI controller; it's a canvas for your musical innovation.
