Eventide® H910 Harmonizer
-
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.Now You Can:
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
Take A Listen
Used and Abused since 1976
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 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.
An End-to-End H910 Circuit Emulation
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
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.

“The Eventide H910 Harmonizer plug-in is the perfect blend of vintage technology in a feature-rich, modern format. Eminently useful and every bit as unique as the original hardware.”
– Richard Chycki (Rush, Aerosmith, Dream Theater)
“In 1975, the Eventide H910 Harmonizer firmly planted its foot in the future. And now in 2015, UA continues to move the past into the future with the Eventide H910 plug-in.”
– Ross Hogarth (Van Halen, Ziggy Marley, Motley Crue)
“The Eventide H910 is a go-to effect for me. With the UAD version, I have to be careful to not overdo it now that I have something that's so good, quick, and reliable”
– Joey Waronker (Atoms for Peace, Beck, Other Lives)
“The Eventide H910 Harmonizer is perfect for a double track effect on the lead vocal by slightly shifting the pitch and adding a short delay. ”
– Joe Chiccarelli (Jason Mraz, Beck, The Strokes, Morrissey)
“The Eventide H910 Harmonizer plug-in is so much fun – I can get lost in it for hours.”
– Jacknife Lee (R.E.M, The Cars, Snow Patrol)Customer Reviews

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..

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.

Super!!
Love it! There are presets, just not in the usual place. Great Plugin. Very pleased!

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.
C. Bruce
Great
Love it. Use it on backing vocals
M. Franco
The 80s are here!!!
You can use this on ... everything ... Voice, drums, toms, snare, kick ... This is a great tool if you know how to use it right. READ THE MANUAL to get the best of it!!! 80s are back!

Instant Depth
Just the default setting on an aux bus does wonders. Love the randomness of the detune. Just blend it in to any track. Sounds thick and wide but not obvious.
N. Pinto
A lot more versatile than expected!
You can put this thing on basically everything and it works ;-)

Corrupts Delay Compensation in PT
Consistently corrupts the delay compensation in my PT sessions. Pretty disappointed in UAD's lack of resolution to this issue after all of the money I've invested into using their hardware and software.
P. McLaughlin
I haven't even...
Read the manual yet. I own this and micro pitch and they are different beasts. I like this one for snare widening and that 70s vocal effect. I recommend for back up vocals, gang vocals, lead. I'd like to try it on guitar soon as well.
P. McLaughlin
But what about?
I didn't buy this during my last outing because I had the Microshift. This is different. I'm not gonna lie I go to the Bennie and jets setting and blend it with vocals and snare. It's a very musical pitch-shift and I will say one thing UAD is great at is modeling vintage units.
