D1 Synthesis designs and builds analog electronic music synthesizers. The company is founded on the belief that there are still unexplored regions within the sonic landscape of analog synthesis, waiting to be discovered.

The Modulo is D1 Synthesis's first instrument: a four-voice analog synthesizer created for sonic exploration. It is now in production.

The Modulo is available through Big City Music. Visit the Big City Music product page for pricing, availability, and ordering information.
