Surge is a digital synth and makes no bones about it.
If you have used it in the past, it will be like welcoming an old friend back into your life. If you are new to Surge, welcome to the party. Come on in, the water is fine. 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.
- 3 oscillators per scene.
- 8 versatile oscillator algorithms: Classic, Sine, Wavetable, Window, FM2, FM3, S&H Noise and Audio Input.
- Classic oscillator is a morphable pulse/saw/dual saw oscillator with a sub-oscillator and hard sync.
- FM2/FM3 oscillators consist of a carrier and 2 or 3 modulators and various options.
- Most algorithms (except FM2, FM3 and Audio input) offer up to 16-voice unison at the oscillator level.
- Oscillator FM and ring modulation between oscillators 1-2 and 2-3.
- Most oscillator algorithms (except FM2, FM3 and Sine) are strictly band-limited, yet still cover the entire audible spectrum, delivering a clear, punchy and clean sound.
- Noise generator with variable spectrum.
- 8 effect units arranged as 2 inserts per scene, 2 sends and 2 master effects.
- 13 effect algorithms
- 12 LFO units available, 6 are per voice and 6 are global for the whole scene.
- DAHDSR envelope generators on every LFO.
- 7 deformable LFO waveforms and step sequencer mode.
- Two filter units in 8 different configurations.
- Feedback loop available in 7 of those configurations.
