This was evident in the way that the display would flicker between pitch ratio readings. The system clocks at the heart of the design drifted and wobbled introducing a degree of randomness in the effect not found in later crystal-based, precise digital devices. The design predates the introduction of the CD and digital audio sample rate standards (e.g. In addition to the glitch, all of the quirkiness of the original H910 has been emulated. Not surprisingly, artists found creative ways to use the glitch and, in fact, years later when the H949 was introduced with advanced de-glitching circuitry, some users were disappointed that the glitch was gone. The original H910’s unique pitch change method introduced random ‘glitches’ into the audio and the word ‘glitch’ into the audio engineer’s vocabulary. At extreme settings, you can create unheard-of 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.

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 Eventide H910 Harmonizer® was the world’s first digital effects processor.
