Sixty Four Pixels is a small electronic musical accessory maker based in Brighton, UK, founded by Jason, a software developer and bass player who combined his coding background with an interest in MIDI and Arduino hardware. The company's name comes from its first product, a DIY kit built around an 8x8 LED matrix (sixty-four pixels) used as a mini games console. Products are designed, assembled, and shipped from Brighton by Jason and a small team, with much of the hardware and firmware released as open source under Creative Commons licensing.

The catalog focuses on MIDI utilities and creative control surfaces rather than full instruments. Utility devices include the CV.OCD MIDI-to-CV converter, the Banana Split powered MIDI thru box, the Orange Squeeze MIDI merger, the Synchole MIDI-to-DIN-SYNC converter, and the MIDI Switcher, which triggers low-voltage DC loads such as solenoids, relays, motors, and LEDs from MIDI messages. Creative instruments include the Le Strum and Le Grand Strum chord controllers, which combine Stylophone-style stylus strumming with Omnichord-like chord buttons, the Arpie MIDI arpeggiator, and the Noodlebox four-part CV/gate and MIDI sequencer.

The brand has developed a following in the DIY synth, modular, and MIDI hobbyist communities, with products sold directly through its site, on Tindie, and through boutique electronic music retailers. Schematics, firmware, and build documentation are typically published on GitHub under the maintainer handle hotchk155, reflecting an emphasis on tinkerable, hackable hardware.

Sixty Four Pixels has 2 products cataloged on Equipboard, including MIDI Interfaces and Production & Groove. Their gear is featured by 1 artist, with the strongest followings in Electronic, Rock, and Hip Hop. Notable users include emma essex.
