A substractive hybrid digital synth

Surge, now called Surge XT, is one of the most popular digital synths used by the free software community.

In Surge, each patch contains two scenes which are separate instances of the entire synthesis engine (except effects) that can be used to create layered or split patches. It features 3 oscillators per scene, with 12 versatile oscillator algorithms (Classic, Modern, Wavetable, Window, Sine, FM2, FM3, String, Twist, Alias, S&H Noise and Audio Input), 2 filter units in 8 different configurations and 12 LFO units (6 are per voice and 6 global for the whole scene).

Surge was renamed to "Surge XT" after it was entirely rewritten in JUCE.
