The H910 Harmonizer Plug-in: Recreating Legendary Sound

The H910 Harmonizer stands as the world’s first digital effects processor, renowned for its unmatched combinations of pitch shifting, modulation, and delay. Its distinctive sound has graced countless iconic works by artists ranging from AC/DC to David Bowie to Frank Zappa, making it an irreplaceable tool in the music industry.

As a faithful recreation of the original hardware, the H910 plug-in offers unparalleled creative possibilities. Utilize its pitch-changing capabilities to craft precise musical intervals, perfect harmonies, or add depth to your tracks by spreading guitars, fattening snares, or applying subtle detuning to synths. Pushing the boundaries further, extreme settings enable the creation of unprecedented mechanical sounds, drone effects, or robot-like vocals through self-oscillation, delay, and anti-feedback.
