Unify's built-in FlangeMod effect is a stereo flanger. A flanger is nearly identical to a chorus (see Silky Chorus), except that

  • the DDL range is shorter (only 0.01 to 10 Hz)
  • the modulation is relative to the minimum delay time (unipolar), not symmetric about the mean time (bipolar)
  • a triangle-wave LFO is used
  • feedback is normally non-zero


The FlangeMod GUI features four control knobs, each corresponding to an identically-named parameter available for modulation, as follows:

  • Rate: sets the LFO frequency (0.1 Hz to 10 Hz, default 1 Hz)
  • Depth: sets modulation depth (0 to 100%, default 25%)
  • Feedback: allows a fraction of the output to be fed back to the input of each DDL (0 to 99.5%, default 40%) for a more pronounced effect.
  • Mix: sets the mix between the “dry” (unprocessed, input) signal and the “wet” (processed) signal at the output (percentage, default 50% i.e. even mix of dry and wet)

Tips and Tricks

  • Setting Feedback to 0 and Mix to 100% (no dry signal) yields a stereo vibrato effect
  • High feedback amounts yield a swirling siren-like sound. Extremely high feedback is hard to control.
  • Very low Rate settings with moderate Feedback produce the classic “jet engine” flanger sound.
