Surge

Surge is a polyphonic software synthesizer and VST plugin designed for complex sound generation. It functions as a hybrid synthesis engine, combining subtractive, wavetable, frequency modulation, and physical modeling techniques to produce audio.

The project distinguishes itself through extensive microtuning capabilities, supporting non-standard musical scales and intonations via industry-standard tuning files. It also features an Open Sound Control compatible architecture for remote parameter management and hardware synchronization.

The system covers a broad range of audio engineering capabilities, including modular signal routing, advanced audio modulation with multi-segment envelopes, and digital audio processing via effects chains. It provides tools for real-time audio analysis, MIDI controller mapping, and the layering of independent synthesis instances.

The synthesizer includes a category-based patch browser for organizing and searching sound presets.
