Surge is a subtractive hybrid synthesizer.

Each patch contain two scenes which are separate instances of the entire synthesis engine (except effects) that can be used for layering or split patches. Features a quick category-based patch-browser for the 1010 factory sound patches.
  • 3 oscillators/voice.
  • 8 versatile oscillator algorithms: Classic, Sine, Wavetable (183), Window, FM2, FM3, S/H Noise and Audio-input.
  • The classic oscillator is a morphable pulse/saw/dualsaw oscillator with a sub-oscillator and self-sync.
  • The FM2/FM3 oscillators consists of a 1 carrier with 2/3 modulators and various options.
  • Most algorithms (except FM2, FM3, Sine and Audio-input) offer up to 16-voice unison at the oscillator level.
  • Oscillator FM/ringmodulation.
  • Most oscillator algorithms (except FM2/FM3) are strictly band-limited yet still cover the entire audible spectrum, delivering a clear punchy yet clean sound.
  • Noise generator with variable spectrum.
  • Two filter-units with arrangeable in 8 different configurations.
  • Feedback loop (number of variations inside the parenthesis).
  • Available filter-algorithms: LP12 (3), LP24 (3), LP24L (1-4 poles), HP12 (3), HP24 (3), BP (4), Notch (2), Comb (4), S&H.
  • Filters can self-oscillate (with excitation) and respond amazingly fast to cutoff frequency changes.
  • Waveshaper (5 shapes).
  • 12 LFO-units available to each voice (6 are running on each voice and 6 are shared for the scene).
  • DAHDSR envelope generators on every LFO-unit.
  • 7 deformable LFO-waveforms + 1 drawable/stepsequencer waveform.
  • LFO1 allows envelope retriggering when used as stepsequencer.
  • Extremely fast and flexible modulation routing. Almost every continuous parameter can be modulated.
  • 8 effect units arranged as 2 inserts/scene, 2 sends and 2 master effects.
  • 10 top-quality algorithms: Delay, Reverb, Chorus, Phaser, EQ, Distortion, Conditioner (EQ, stereo-image control & limiter), Rotary speaker, Frequency shifter, Vocoder.

I can't say enough good stuff about this. it has a TON OF PRESETS, so you don't have to tweak for hours. it sounds great and a lot of the sounds, the ones I have gotten around to, are great. for free, amazing. the effects is a separate vst and good if you don't have any effects, but I wouldn't run this through "surge effects". use your fave effects and off you go........

I honestly dont get the whole hype about this plugin, not too many useful sounds, the key/synth patch only has like 7 presets, I dont mind sound designing to create more presets, but this isn't intuitive to me at all, if your gonna use this then get some preset packs, cause without them this plugin isnt all that good.

Excellent. Comes with tons of patches and they are quite easy to navigate through. The tones are nothing special but quite good nonetheless. Some very big and complex sounds here but the presets I've tried still sound musical, not all glitchy and freaky like some of the flashier synths out there. I think this is one of those must have, classic VST synths like Synth1 and Dexed where the basic tones are decent and useable and someone else has done all the programming for you and now it's up to you to simply find a sound you like.

Pity the installer doesn't let you choose where to install files. If I do install it I will have to find all the components and move them to my VST folder.

Love this damn synth my friends. Slapping it all over a project im working on. I find it kind of has its own character to it. I'd recommend turning off built in effects on any presets you use, but it's full of amazing unique tones.

I'd literally pay for this, such a complete synth! You cant get much better than this for free! If you like this I'd recommend trying out ZynAddSubFX, another FOSS soft synth that's really powerful!

A few very minor bugs : if re-scaled, the UI resise when changing presets, and depending on how the presets are changed it does'nt update the new preset name on the UI (FL Studio x32). Despite these minor annoyances, this synth is a true gem ! I really love the very logical interface, the amazing sound, and the incredible potential and power of this synth. Really excellent !!!

BEST FREE SYNTH EVER. Subtractive, FM, Wave-table(supports import) Hybrid synthesis(even allows for audio input). This thing is in a class of its own, free or paid. Extremely flexible. Low on the CPU. Not much it can't do. 5/5

Surge is an excellent virtual synthesizer. It offers a large number of patches that allow it to be used in any project. An aspect to highlight is the possibility of crossing waves in each of its oscillators; which allows modifying the timbres and trying to find what you are looking for. I think it should be one of the first on the list.

Don't understand the hype about Surge – it sounds terrible. It's just so thin that you would think it comes straight from 2001. I prefer ZynAddSubFX over this overhyped toy.
Digital Rules Dec 01 2019

How dare you?! Infidel! Just kidding. =) But seriously I think people like Surge so much because of the very wide range of sounds it can produce. Surge has a rather unique and complicated synthesis architecture and that gives you a huge sonic palette. Also Surge is 10+ years old so maybe that is why it may sound thin to some.
Proteus Dec 25 2019

Surge is more than a good decade old synth so it is understood that it can hardly compete with the current synths. Though I think it still has a very special and unique sound and character. It can make very uncommon and uncharted sounds and noises.

Probably the best sounding free synth with Tyrell ns6 and TAL noisemaker. (and Synth1 of course !). The UI is resizable (v 1.6.2.1). Comes with really nice presets. note 5/5

Not perfect, I use FL in 32bit and noted two problems, the windows resize is buggy when changing patches, and when browsing patches, the patch names doesn't update.... Still, even with those small issues, I give it 5 stars ! It has an easy and straightforward user interface. The patches are numerous and quite good for my taste (and a good starting point for further tweeking). The help file is very well written. It is a extremely powerfull and polivalent synth and still pretty easy to understand.

Awesome news, folks! Surge got a big update and is now Windows 32-/64-bit VST/VST3, Mac OS 64-bit AU/VST/VST3 and Linux 64-bit VST/VST3! It is now actively being developed by new, cool and dedicated developers. How cool is that?! Surge sounds brilliant by the way! =)

Possibly the only synth you'll ever need. I usually prefer hardware emulations but this makes excellent use of digital excellence. I don't know if I will use anything else from now on, except just for fun. The presets on their own are awesome, I can only imagine what can be done with some thoughtful programming. Sounds fantastic!

Wavetable synthesis has always been my favorite technique. Surge was ahead of the game. I'm kinda shocked at how recently it's become popular. People were looking down their noses at some of us early Surge adopters back in the day. But now Surge is well accepted and there's a lot more competition all of a sudden. Anyways, it's always been and still is a really nice synth. It does NOT have to be used for recent trendy sounds or just for the presets. It's fairly capable of a lot of things. With proper additional EQ and compression, you can get some pro sounds that work well in an actual production mix. Also, the single cycle waveforms in WAV form are somewhat interchangeable between Image-Line Harmor, Image-Line Toxic Biohazard, and Vember Surge. AKWF's is also compatible. (Adventure Kid WaveForms)
