The Eventide H910 Harmonizer was developed by Eventide in 1974. The H910 was the world’s first commercially available digital audio effects device. It combined ‘de-glitched’ pitch change with delay and feedback. It could be controlled by a keyboard remote control to instantly shift pitch in half steps. It featured a two-octave range and up to 112.5 msec of delay. The combination of pitch change, delay, and feedback opened up a new world of sonic possibilities which were exploited in the ground-breaking work by artists from AC/DC to David Bowie to Frank Zappa.

The Eventide H910 Harmonizer effects processor forever changed the complexion of music enabling producers and artists to add texture to their recordings and performances in ways heretofore unimaginable.
