In September 2018 I reported about Surge, a well-known synthesizer plug-in that was taken off the market but lives on as an open-source project. The developer has now upgraded Surge and there are two very good news: it is now compatible with Windows / Mac / Linux and MPE is supported.

Surge is a powerful synth (wavetable, FM…) is now available in a first beta as a free download. Now there is no reason not to download it.

News From September 26th, 2018

Sad news comes from Vember Audio. The developer announced today that SURGE Synthesizer plugin is no longer being developed. Especially because the developer has no time left. But nobody has to be sad now. This message also has a good page.

SURGE is now open-source and can be developed by anyone under the GNU GPL v3 license. It’s a powerful hybrid subtractive synth that comes with many oscillator algorithms, two filters, plenty of modulations (12 LFO’s…, effects and more. The plugin is currently only available for Windows users but a macOS version could come very soon because the code ready for a macOS version.


Architecturally speaking, Surge is a rather complex synthesizer. But because of how it’s put together it’s still easy to learn.
