Surge 1.9

Surge 1.9

Surge 1.9 is a huge update with tons of new features and improvements.

Here are a few new feature highlights

  • 4 new oscillator types: a modern low aliasing waveshape oscillator, an alias, a string waveguide-based feedback oscillator as well Twist. The latter is based on the famous multi-oscillator module Plaits from Mutable Instruments.
  • 14 new effects:
    • Effects by Jatin Chowdhury including Neuron, a distortion effect (Gated Reccurent Unit), CHOW, a truculent distortion effect , Exciter, an aural exciter unit, and Tape, a compact implementation of Chow Tape Model.
    • 11-band graphical EQ 
    • resonator takes inspiration from a very well-known vintage hybrid poly synth that rhymes with “vogue”. Plus expanded with a few Surge-inspired additions.
    • combulator, a novel bank of 3 comb filters with feedback, additional noise exciter, separate output volumes for each comb, and individual panning for two out of three combs
    • ensemble effect with several BBD modes and a clean delay mode, uses a very famous tri-phase dual LFO modulation setup
    • nimbus, a live input granular processor with built-in reverb based on the Mutable Instruments Clouds module.
    • treemonster, a really wild pitch-tracking ring modulator from Shortcircuit 2, proper Vember Audio classic!
    • five new Airwindows effects including Galactic, Infinity, Verbity, MatrixVerb, and TripleSpread
  • ODDSound MTS-ESP as a tuning source.
  • … and more.


Then, the developers have adjusted the existing engine and improved it in many areas. Here are some highlights:

  • 4 new waveshapes in the sine oscillator
  • oscillator drift now works properly for all oscillator types
  • single-cycle wavetable support
  • FM2 and FM3 oscillator types now have an extended range for feedback parameter by default & more
  • … and more
