H910 Harmonizer.

The H910 Harmonizer plug-in recreates Eventide's 1975 pitch changer section by section, from its custom converter, companding and filtering to the wandering clocks and random glitches that made it sound unsteady and alive. Pitch is set by hand or follows the Anti-Feedback wobble around unison, an envelope follower or notes played over MIDI, with separately set delays and a feedback loop behind it. Reach for it to widen guitars, thicken a snare, detune a synth or stack a vocal harmony, then turn up feedback for robotic spirals and drones.
