Seaquence is a beautiful and lush sounding synthesizer with vast potential for creativity and exploration.

Its uniquely designed interface allows you to create music with swimming creatures in a stereo mixing dish. Multiple voices are heard simultaneously, resulting in layered, dynamic compositions. Seaquence's wide sonic template allows you to create everything from ambient drones to intricately layered rhythms and transients.

With its playful and colorful interface, even composers who are brand new to music will be able to unlock their synesthetic creativity. You can save your sessions, post and share them, and explore the Seaquence Galaxy to listen what others have shared and get inspired!

Upgrading to Seaquence Complete unlocks more tools, effects, and Midi i/o support.
