Semicircular is a Berlin-based maker of high-quality, portable cases for Serge Modular Synthesizers in 4U format.

The lack of a briefcase-style solution in the market place led us to develop a case equally suited for studio, stage, and the road.

We plan to also offer a Loudest Warning format case in the future.
