A powerful tool for creative producers and engineers alike, the H910 plug-in for AAX. 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. Let’s face it, Harmonizer is a great name. The H910 Harmonizer was the world’s first digital effects processor. The Varispeech was described in the literature as a way of time correcting speech, while the Harmonizer was sold from the get-go as something to generate musical harmonies. Includes artist presets from Richard Devine, Jeremy Lubsey, Alex Saltz, Sebastian Arocha Morton, Richard X, and John McCaig.

Add or remove filters to customize your sound. If I had to guess, it has something to do with marketing. Eventide Physion Transient and Tonal Shaper Plugin. So, why did the H910 become identified with pitch shifting, and the term “Harmonizer” become almost as generic as “Xerox” (at least in recording circles), while the Lexicon Varispeech faded into relative obscurity? I don’t know. The H910 appears to use a fairly simple triangle wave crossfading, which means that the 2 different delayed signals will be present to a greater or lesser extent in the output at virtually all times. Like the Lexicon Varispeech that preceded it, the H910 would be what I would label a 2-tap pitch shifter, in that there were 2 pitch shifted signals, with crossfading between the 2 signals. In 1975, Eventide came out with their first Harmonizer, the H910:ĭesigned by Anthony Agnello (later of Princeton Digital), this was a digital variant of the rotary tape head pitch shifters that I discussed earlier.
