Stretch “the fabric of time” with this pioneering 1970s multi-effects unit.

Introduced in the mid-’70s, the Eventide H910 Harmonizer was the first commercially available digital audio effects unit. Its unique analog/digital circuit generated iconic pitch change, delay, and modulation effects in previously impossible combinations — with a sound that’s prized to this day.

From sci-fi sound design to pop music landmarks from David Bowie and AC/DC, the Eventide H910 is an unmatched creative tool. Today, Eventide and Universal Audio proudly announce the Eventide H910 Harmonizer plug-in, an end-to-end circuit emulation of this legendary processor.

Get iconic Eventide H910 pitch change, delay, and modulation effects in real time

Thicken drums, guitars, and vocals with subtle and organic detuning

Craft hazy delays, slapback echoes, ambient textures, or drone feedback

Pitch audio +/- one octave without time compression or expansion — controllable from a MIDI keyboard

Use the H910's pitch changing ability to create specific musical intervals and musical harmonies

Harness presets from Richard Chycki, Tom Lord-Alge, Tony Platt and more

A powerful tool for creative producers and engineers alike, the Eventide H910 hardware excelled at straight-ahead guitar or vocal thickening, regenerative arpeggios, and bizarre sound design effects. On classics like David Bowie’s Low, and Iggy Pop’s The Idiot, producer Tony Visconti used the H910 to pitch down drum sounds, famously saying it, “f*cked with the fabric of time.” World’s away, AC/DC engineer Tony Platt put the H910 to slyly fatten up Back in Black’s iconic snare sound, while Eddie Van Halen used two H910’s for max spread on his 80’s guitar tones.

The Glitch is Back

The Glitch is Back

The H910 introduced the word “glitch” into the audio engineer’s vocabulary. The H910’s pitch change relied on extensive analog processing. While simple, this circuit allows you to explore unique, unpredictable effects, never before emulated in a plug-in.

In developing this landmark processor for the UAD and Apollo platforms, Eventide modeled the H910’s entire analog/digital circuit, including its custom-built A/D converter. This allows the UAD H910 Harmonizer plug-in to retain the original hardware’s characteristic tone, as well as its dynamic responsiveness to input signals.

Keyboard and MIDI Mapping

Keyboard and MIDI Mapping

The keyboard was an integral part of the H910’s original concept, and was later offered as an option. With the H910 plug-in, you can easily use MIDI to control pitch and harmonization in real time. But beware, one test drive of the H910 plug-in, and you’ll discover sounds that you can’t live without.

Cant scroll presets

Unlike all the other UAD plugins you can't scroll presets with this one. which is a real bummer as the presets are so dramatic from one to the other- they say it's the developers fault.. passing the buck. What ever happened to Quality control? It's also a DSP hog.

Very specific, fairly weird, but amazing

Just started to scratch the surface of the H910. It uses a lot of DSP, but is a very powerful tool. Plan on printing it and then removing the plugin to free up DSP. Very surgical for thickening up tracks, or it can get downright metaphysical as well. One of the more interesting plugins to mess around with. Not the first one I’d buy, but if you’re looking for something different or need to thicken or play with the pitch, the H910 can do it

H910 Harmonizer

My UAD best version of the H910 could not be accurately reviewed because it has no presets. It actually does work at all. I have the Eventide H910 vst Version through another audio company, and because I liked the Plugin, I wanted to get UADs take on it. Unfortunately, all attempts at customer service are not available. I am banned from complaining when things don't work correct by ULA.

One of my favorites

Use 2 in their own send bus each slightly detuned to fatten up the ordinary. Sounds better than the original.

This UAD plugin eats your dsp

The plugin it self is quite cool and were used by ABBA as Led Zeppelin, it has absolutely it's strengths both as a delay and as a pitch-shifter, but it literally eats your DSP. I've two 16 cards and I still think it uses 8 or 12% of ONE SINGLE unit once automated... it's not okey. The plugin is with other words very poor programmed compared to UAD's own products like 1176 and such which you can stack 4-8 units equally dps usage to one single 910 harmonizer... with that being said.. if you can achieve the pitch things or delay things with other units or plugins I'd strongly recommend be used with that or just buy the hardware..

short text:
+ Cool effect unit

- eating your DSP
- poor programmed

Like the real thing

After playing around with this plug for a bit I soon realized it was the bit of magic some of my fave producers have used to create some wildness in their tracks.

Great on drums!

Getting spectacular snare drum sounds. So far, I've only gone through the presets. Bought it because I hoped I'd get believable vocal doubles. I can say that it's better at that task than anything else I've tried, and I've tried several dedicated doubler plug-ins, including "signature" plugs. But it's still not quite good enough that I'd actually use it for that. I expect to find other uses for this fascinating plug-in, but it's too soon to say.

Blows away soundtoys micro shift out of the water.

I’ve used sound toys micro shift for years and always wanted to purchase the uad eventide but convinced myself to save money and use what I already have the “micro shift” I finally caved after I tried a demo and purchased the eventide. I absolutely love it and it’s the sauce. micro shift is great this is even better.
