Sweeper offers three separate stereo modulation effects: phaser, flanger and filter. The pristine-sounding phaser offers up to a whopping 40 stages for some extreme phasing sounds. The Flanger excels at the sweeping sounds you’d expect from it while the filter section is the oversampled filter from Europa with nine filter modes. To breathe life into the effect, Sweeper has a modulator with a looping envelope, an audio follower and audio trig to modulate just about any of Sweeper’s settings.
