Released in the mid-1970s, the Eventide H910 Harmonizer was the first digital audio effects unit available commercially, blending analog and digital circuits to create groundbreaking pitch shifting, delay, and modulation effects. Its distinctive sound, known for producing rich, organic detuning and unique audio textures, has been widely celebrated and remains influential in music production today. The plug-in version faithfully recreates this classic processor, offering musicians and producers the ability to apply these iconic effects in real time within their digital audio workstations.

The Eventide H910 has played a significant role in shaping the sonic character of many landmark recordings, from David Bowie and Iggy Pop to AC/DC and Eddie Van Halen. It excels at enhancing drums, guitars, and vocals with thickening effects, creating ambient textures, slapback echoes, and pitch shifts up to an octave without altering timing. By using MIDI control, users can craft precise musical harmonies and intervals, expanding creative possibilities. The plug-in also includes presets from renowned engineers, enabling quick access to signature sounds that have influenced decades of music.

This plug-in delivers an authentic end-to-end emulation of the original hardware, including its custom analog-to-digital converter and analog processing stages, preserving the dynamic responsiveness and character that made the H910 legendary. Known for introducing the concept of 'glitch' in audio effects, it offers users the chance to explore unpredictable and expressive sound manipulations not previously available in software form. The integration of keyboard and MIDI mapping makes real-time pitch control intuitive, inviting producers and engineers to rediscover the creative potential of this pioneering harmonizer.
