Eventide Clockworks H910 Harmonizer

FEATURES OF THE H910 HARMONIZER

PITCH CHANGE – Shifts pitch one octave up or down while preserving harmonic ratios. The continuously variable pitch control allows precise interval selection, displayed on a 3-digit LED. An optional keyboard enables pitch changes in musical steps.

DELAY AND REVERB – A versatile digital delay line for vocal doubling, delay equalization, and special effects like reverb and echo. Two variable-delay outputs enable vocal multiplying, speaker distribution (great for PA use), and more.

ANTI-FEEDBACK – Reduces feedback by periodically shifting pitch up and down, preventing resonance buildup. Unlike heterodyne frequency shifters, it avoids dissonance.

SPECIAL EFFECTS – Combining feedback, delay, and pitch change creates unique effects. Pitch shifting with feedback produces a musical progression, while pitch changes without delay create robotic or alien speech. Short delays with feedback give flanging effects, and long delays create a distinct reverb.
