Eventide H949 Harmonizer Plugin

The World’s First Time Machine

Building on the legacy of the H910 pitch shifter, the H949 was Eventide’s first de-glitched pitch-shifter. Produced from 1977 - 1984, it introduced MicroPitch which used a proprietary single sideband modulation technique for precise control of small pitch shifts. The H949 also offered unique flange, reverse and randomized pitch effects.

Multiple Uses

Create perfect harmonies, custom musical intervals, or outlandish effects. Fatten snares, de-tune synths, spread guitars and create lush vocals that glue your mix. Spice up your guitar solos with delayed reverse sweeps, morph a solo vocalist into a group of backup singers, or send synths down flanged-out dub-holes to another sonic dimension.

De-glitched Pitch Change

The H949 algorithm uses a proprietary auto-correlation algorithm to make intelligent splicing decisions. The user can ‘dumb-down’ the algorithm by choosing a simple cross-fade algorithm which results in characteristic glitching.

Twist the Knobs

Old school “UI” - just twist some knobs to dial in the sound you’re going for.

Double Down

This native plug-in version also includes the H949 Dual, which recreates the popular technique of running two units in parallel. Lush doubling, stereo widening and simultaneous shifting of pitch up and down.
