Envelope Follower - 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.

With the H910 plug-in you can easily use MIDI to control pitch and harmonization in real-time.

Keyboard and MIDI mapping - The original H910 featured a keyboard remote control which was used live by several artists including Elton John.

This version recreates the popular technique of running two H910 units in parallel to create lush doubling and other interesting effects. When you purchase the H910 Harmonizer® plug-in, you also receive Eventide’s exclusive H910 Dual Harmonizer®. At extreme settings, you can create unheard-of mechanical sounds and drone effects using self-oscillation, delay, and anti-feedback. Use the H910's pitch changing ability to create specific musical intervals and harmonies, spread guitars, fatten snares, apply subtle organic de-tuning to synths or add slap-back delays to vocals. Simply put, nothing sounds quite like it.Ī powerful creative tool, the H910 plug-in is a faithful recreation of the original hardware. With its unique combinations of pitch shifting, modulation and delay, the H910 can be heard on countless ground-breaking works by artists from AC/DC to David Bowie to Frank Zappa. The H910 Harmonizer® was the world’s first digital effects processor.
