Surge

Surge is a free and open-source multi-platform hybrid digital synthesizer. Thanks to the generosity of @Kurasu (owner of Vember Audio), Surge has been open sourced and lives on GitHub. This page you're reading right now. Yup. This one right here. It's part of the GitHub OSS Surge-Synthesizer project.
