H910 by Eventide is a pitch shifter harmonizer plug-in that emulates the original hardware which was the first digital effects processor in the world. With the pitch-shifting ability of this plug-in, you can create impressive musical intervals that are paired with golden harmonies and spread guitars. With it, you can also create flattened snares or apply delicate organic de-tuning to a wide variety of synths and delays to vocals. With its interesting combinations of pitch shifting, modulation and delay, the H910 can be listened to on endless ground-breaking works by artists from AC/DC to David Bowie to Frank Zappa. Basically, nothing sounds very like the H910.
