Doepfer

Doepfer Musikelektronik is a German electronics company that specializes in modular synthesizers and related equipment. It was founded by Dieter Doepfer in the mid-1990s and is best known for creating the Eurorack modular synthesis format and the A-100 modular system, a widely used platform for building analog synthesis rigs.

Eurorack, the standard Doepfer helped establish, is a compact modular format that uses standardized module sizes and a common power system to enable interoperability among modules from many manufacturers. The format gained widespread adoption and contributed to a resurgence of modular synthesis in the 2000s and beyond. The A-100 family remains a core product line, offering modules such as voltage-controlled oscillators, filters, envelopes, VCAs, LFOs, and a variety of utility and fixed-architecture modules.

Doepfer’s product range extends beyond the basic A-100 modules to include MIDI-to-CV interfaces, CV-to-MIDI interfaces, digital and hybrid modules, as well as racks, power supplies, and cabling designed for Eurorack setups. The company maintains documentation and a distribution network that serves customers worldwide through direct sales and authorized resellers. Doepfer products are recognized for robustness, affordability, and breadth, making the company a foundational supplier within the modular synthesis community.
