The analog sections of the H910, including companding, filtering and analog feedback made gave the unit a distinctive sound which this plug-in faithfully re-creates. It was designed before high fidelity audio analog to digital converters were available and necessitated that Eventide design its own custom conversion which played a significant part in the sonic quality of the H910. It used digital logic and some of the earliest RAM memory to achieve delay but was, in large measure, an analog beast. While the H910 was ‘digital’ it was 100% software free – it pre-dated the earliest DSP chips by several years. The H910 was the first commercially available audio pitch change device and, in 2007, along with the Thermin, it was inducted in the TECnology Hall of Fame. The H910 was used to create the effects heard on records since the late seventies. 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.
It featured a two octave range and up to 112.5 msec of delay. It could be controlled by a keyboard remote control to instantly shift pitch in half steps. It combined ‘de-glitched’ pitch change with delay and feedback. The H910 was the world’s first commercially available digital audio effects device. The Eventide H910 Harmonizer was developed by Eventide in 1974.
