Philip Rees ran a small British electronics workshop that designed and built MIDI accessories from 1986 through the mid-2000s. The line started with the 5X5, a five-input, five-output MIDI patchbay, and grew into a catalog of utility boxes aimed at studio and live-rig wiring problems: MIDI Thru units, Merge units, Selectors, the TS1 tape sync, MIDI-to-CV converters, line drivers, and MIDI foot controllers. The compact, no-frills boxes became a common sight in home and project studios trying to route signal between hardware sequencers, synths, and drum machines.

Later products included the Little MCV MIDI-to-CV converter, reviewed in Sound on Sound, and the C16 MIDI Control Unit launched in 2000. From 2002 onward, the workshop shifted focus toward building quiet, specialist PCs aimed at music production, and discontinued the MIDI accessory range in 2005. The brand is remembered chiefly for inexpensive, reliable MIDI plumbing that filled gaps the bigger manufacturers ignored.

Philip Rees has 5 products cataloged on Equipboard, including MIDI Interfaces and Metronomes.
