S-Modular

By Paul Betowski

S-Modular is a single-screen semi-modular synthesizer for iPad that facilitates hands-on sound design through a drag-and-drop patching interface. It aims to replicate the warm, vintage character of 1970s analog synthesis using a variety of integrated sound-shaping modules. The app is notable for its immediate, clutter-free workflow, though it currently lacks external control integration.
