The Eventide H3000 is one of the most iconic effect hardware processors ever released. It was (and still is, despite its age) a multi-effects powerhouse combining Eventide’s standard-setting, pitch-shifting algorithms, along with delays, a comprehensive library of modulation effects, and powerful reverb algorithms in a modular, upgradeable package.
The H3000 (and the later models) helped create and shape the sound of these past few decades. I think this letter from Brian Eno to the Eventide team explains the success of this groundbreaking piece of gear better than I could ever do.
Many years later, this classic piece of gear gracefully entered the software arena, with its plugin H3000 Factory version.
H3000 Factory is a re-creation of several key algorithms from the H3000 Harmonizer combining pitch, delay, modulation, and filtering. It includes over 450 presets, including 100 presets from the original hardware.
