Our team has over 30 years of experience in synthesizer design, and is now focusing it all on Rain City.

The Sequencer Construction Set (SCS)

Our flagship offering is the Sequencer Construction Set (SCS)—a modular ecosystem designed to empower custom sequencing systems that are tailored to each user's needs. Rather than constraining you to a single self-contained sequencer, the SCS system lets you build, expand, and tailor your sequencing environment to match your unique workflow.

SCS-V, SCS-T, SCS-S, SCS-C and SCS-X are among Rain City Modulars most popular products.
