H910 Harmonizer

H910 H910

The H910 Harmonizer was the world's first digital effects processor. With its unique combinations of pitch shifting, modulation, and delay, the H910 has made its way onto countless ground-breaking work by artists from AC/DC to David Bowie to Frank Zappa.

A powerful tool for creative producers and engineers alike, the H910 plug-in for AAX, VST and AU is a faithful recreation of the original hardware. Create unheard mechanical sounds, drone effects, or robot language using self-oscillation, delay, and anti-feedback. Use the H910's pitch changing ability to create specific musical intervals and perfect harmonies, spread guitars, fatten snares, apply subtle organic de-tuning to synths, or add slap-back delays to vocals.


  • NEW Keyboard and MIDI mapping - The original H910 featured a keyboard remote control which was used live by several artists including Elton John. With the H910 plug-in you can easily use MIDI to control pitch and harmonization in real-time.
  • NEW Envelope Follower - An envelope follower has also been implemented in this latest release. Engineers and producers discovered that sending a control voltage to the hardware H910 could be used to slightly (or massively) vary the pitch, creating entirely new sounds. The built-in envelope follower makes exploring these possibilities easy.
  • NEW OUT2 Delay Group - adds inspiring attributes to your sound.
  • True analog modeling of highly nonlinear electronics for faithful reproduction of original juicyness and grit.
  • Perform perfect pitch changes. Control them manually, via MIDI or with Anti-Feedback.
  • Anti-Feedback modulates the pitch around unity for a subtle or wild effect.
  • Glitching of original hardware present to create unpredictable sounds as it alters pitch.
  • Modify pitch by musical intervals to harmonize vocals or solo instruments.
  • Delay rhythms and melodies to create everything from slap-back echoes to crystalizing feedback chaos.
  • Create colorful, unique sound effects and drones through self-oscillation.
  • Individually control delay outputs and dry/wet mix.
  • Mix Lock allows for scrolling through presets or settings while keeping the dry/wet mix constant.

Two is Better than One

When you purchase the H910 Harmonizer plug-in, you also receive Eventide's exclusive H910 Dual Harmonizer. This version recreates the popular technique of running two H910 units in parallel to create lush doubling and other interesting effects.

Version reviewed: 1.0 on Windows

The H910 and H910 Dual Effects Harmonizer is based of a 70's Eventide model used by David Bowie and Many Others, This Plugin is a faithful emulation of the sounds of the real life harmonizer unit being the dual is having two units chained together which was a popular method of link two units together to get a thicker sound, the pitch control range from octaves, semi-tones to micro-pitches, to harmonies 5th and 7th via semi-tones.

I am satisfied with my purchase of eventide's recreation of their 70's effects unit, Smooth activation and easy to use controls, I got it on intro-price but you can get now for 249 USD. I believe if your looking for a way to thinken up vocals or add extra punch to guitar you can use this and it would fit perfectly.
