OSL Chorus

Chorus by Oblivion Sound Lab

Free Product

A Lush Effect Inspired by the Onboard Chorus of the Juno 60 Synthesiser

OSL Chorus is modelled after the Juno 60’s onboard chorus. It produces rich, wide choruses that are perfect for bringing dry synthesisers to life, but it sounds equally good on guitar, bass, and other instruments.

In its default configuration OSL Chorus emulates the original unit, but adjustable parameters let you dial in custom choruses that range from subtle to extreme.


  • Adjustable LFO rate and depth
  • Adjustable delay offset
  • Low pass filter to control the chorus brightness
  • Separate dry and wet controls for precise mix levels
  • All parameters can be automated from the host DAW
  • Supports stereo-to-stereo and mono-to-stereo channels
  • Compatible with 32 and 64 bit hosts
