The Surge open source synthesizer instrument by Vember Audio has been updated to version 1.6.3.

Surge is a virtual synthesizer released into open source by creator Claes Johanson in September 2018, and maintained by a group of volunteers since then.

The update comes with fixes for various problems with the VST3 plugin.

Changes in Surge v1.6.3

  • VST3 Fixes:
    • Pitchwheel and Modwheel work VST3/Cubase.
    • Resolved bugs in MIDI mapping, MIDI learn, and other controller flows.
    • Resolve VST3 automation inconsistently updating the Surge UI.
    • Support drag-to-zoom in VST3 in hosts which support it (tested in Reaper, FL, Bitwig and Cubase).
  • Upgraded the distortion effect:
    • Users can select the waveshaper for the drive stage from the set of surge waveshapers.
    • The pre- and post- gain can be extended to allow outsized boosts and subsequent extreme distortions.
    • Note that some settings of the distortion effect in extended mode can drive Surge well into digital clipping. Be careful.
  • New patches from Inigo Kennedy.
  • Several LV2 and Linux changes, including the ability to build a 32-bit Linux configuration.
  • Deal with some small bugs with wave ordering, invalid waves, menu arrow keys on Linux, and error handling when Surge is mis-installed.

Surge is available as a free download with binaries available for Windows, Mac and Linux (VST/VST3, AU and LV2 formats).
