Modcan is a modular synthesizer manufacturer based in Toronto, Canada, founded by Bruce Duncan. The name is a contraction of "Modular Canada," reflecting Duncan's roots and the company's place as one of the earliest builders to reintroduce analog modular synthesis to the post-MIDI marketplace. Duncan, who began his career as a model-maker for architects and industrial designers and apprenticed in lute-making, started building synth modules as a hobby in the mid-1990s before turning Modcan into a full-time operation.

The company is best known for its hand-built analog modules, offered in three formats: the original A Series, which uses color-coded banana jacks; the B Series, introduced in 2005, which shares the A Series circuitry but adopts MOTM-compatible rack sizing with 1/4" jacks; and a Eurorack line. Module categories span oscillators, filters, envelopes, VCAs and mixers, LFOs, sequencers, effects, and CV processing. Modules are assembled to order using metal film resistors, water-soluble flux soldering, and ultrasonic washing.

Modcan's instruments earned a reputation among electronic musicians and producers seeking warm, character-rich analog tone, and have been associated with high-profile electronic acts including Daft Punk and Deadmau5. The brand is often discussed alongside fellow Canadian builder Intellijel as part of Toronto's modular synth scene.

Modcan has 24 products cataloged on Equipboard, including Modular Synthesizers. Their gear is featured by 7 artists, with the strongest followings in Electronic and Rock. Notable users include Deadmau5, Richard Devine, and Daft Punk.
