We think it's pretty cool that you picked Surge for the One Synth Challenge.
A group of musicians over at OSC created these songs using Surge 1.6 only!
Do give them a
As great things are bound to repeat themselves, Surge was chosen as the featured synth once again, for OSC
138! This time, it was Surge 1.7 taking all of the sound generation duties. That just means there is even
more music featuring Surge available for your listening enjoyment!
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 is back and open source!
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 surge-synthesizer GitHub project.
Synthesis method: Subtractive hybrid
Each patch contain two scenes which are separate instances of the entire synthesis engine (except
effects) that can be used to create layered or split patches.

Runs on a variety of operating systems, plugin formats, and architectures
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.
Classic oscillator is a morphable pulse/saw/dual saw oscillator with a sub-oscillator and hard sync.
Modern oscillator is a mixable saw/pulse/triangle oscillator with an optional sub-oscillator mode for
triangle (which can also change to sine or square) and hard sync.
FM2/FM3 oscillators consist of a carrier and 2 or 3 modulators and various options.
String oscillator uses two filtered waveguides to emulate plucked or bowed string sounds.
Twist oscillator is based on a very famous Eurorack macro oscillator, and it offers a myriad of
synthesis options in a very simple and quick way.
Most algorithms (except FM2, FM3, Twist and Audio Input) offer up to 16-voice unison at the oscillator
Oscillator FM in 3 different configurations and ring modulation between oscillators 1-2 and 2-3.
Most oscillator algorithms (except FM2, FM3, Sine and Alias) are strictly band-limited, yet still cover
the entire audible spectrum, delivering a clear, punchy and clean sound.
Noise generator with variable spectrum (available directly in the oscillator mixer).
Two filter units in 8 different configurations.
Feedback loop available in 7 of those configurations.
Available filter algorithms: Lowpass (12 and 24 dB/oct, each with 3 variations), Legacy Ladder Lowpass
(6-24 dB/oct), Vintage Ladder Lowpass (2 variations, each with and without gain compensation), Highpass
(12 and 24 dB/oct, each with 3 variations), Bandpass (12 and 24 dB/oct, each with 3 variations), Notch
(12 and 24 dB/oct, each with 2 variations), Allpass (3 variations), Comb (positive and negative),
Open-source additions to our filter bank contain: K35 and Diode Ladder filter types from Odin 2
synthesizer, 12 and 24 dB/oct multimode filters from OB-Xd, and weird but fascinating Cutoff Warp and
Resonance Warp filters by Jatin Chowdhury!
Filters can self-oscillate (with excitation) and respond amazingly fast to cutoff frequency changes.
Waveshaper (5 shapes).
12 LFO units available, 6 are per voice and 6 are global for the whole scene.
DAHDSR envelope generators on every LFO.
LFO shapes consist of 7 deformable LFO waveforms, step sequencer, and a fully-fledged multi-segment
envelope generator (MSEG), with various curves and up to 128 nodes.
Voice LFOs allow envelope retriggering in step sequencer mode.
Extremely fast and flexible modulation routing. Almost every continuous parameter can be modulated!
8 effect units arranged as 2 inserts per scene, 2 sends and 2 master effects.
