Analogue Systems
Bob Williams began in 1995 like Doepfer, but unbeknown, with the production of a modular system in Eurorack-format. The first modules were extractions from earlier Analogue Systems products like the FB-3 filter bank. Analogue Systems lately introduced the Dual Bus, so nearly all modules are now easy to connect to the more common Doepfer style busboards.
A few modules such as the classic EMS Eurorack versions are now also available with slick new front panels.
