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

Eventide harmonizer great for thickening up parts
We bought the Eventide to thicken up vocals,synth and bass and to add a great chorusing effect. But that is just the surface of what this plugin can add to the mix! because it is a far out...

UAD vs. Eventide
Eventide has presets (smart) and UAD doesn't (not smart)...

One of the few plug-ins I'm not absolutely thrilled with
Good as far as it goes and useful. But the noise and middling fidelity are a bit TOO authentic for my taste. It's 2020 not 1975 and there should be a way to get sound quality comparable...

Instant clean stereo
Though there are many applications of this plugin, I often drop it on and default preset gives me that stereo width I was hoping for.

Eventide harmonizer great for thickening up parts
We bought the Eventide to thicken up vocals,synth and bass and to add a great chorusing effect. But that is just the surface of what this plugin can add to the mix! because it is a far out vintage special effects unit that will really add spice to any track. Read the manual because the Evantide is deep.

Good as far as it goes and useful. But the noise and middling fidelity are a bit TOO authentic for my taste. It's 2020 not 1975 and there should be a way to get sound quality comparable to other plug-ins. Uses a lot of DSP.

My favourite toy
Used the hardware w Delta Lab and AMS gear for shows as well as recording.The Eventide plugin is brilliant.Well done.Cheers
R. Hortensius
Awesome sounding effect !
This sounds great on almost anything even makes vocals sound decent used sparingly ! Been trying out the demo...just wished I had a voucher now.
C. Turbin
Just Awesome
Now my go-to effect for delayed out stranger pitchy reverbs. No more need for three plugins inserted to get these sounds. I haven’t even tried it with the midi inputting yet but as soon as a song calls for that I’m THERE.

The Sound Of The 80`s
like voice capitain Future Battlestar Galactica German zylon robot voice and the six milions dollar man German 80´S TV Series white the plug the 80`s is back in the 2019
M. Kavvadias
Awesome sound, but where are the presets?
I love it, use it on vocals, guitars all the time, it is just great. But... someday the presets disappeared from the menu! Strange but true. I think it's a known issue but not fixed yet.
Otherwise a 5 star plugin.E. Blake
Takes me back
Brilliant plugin.We used the hardware Eventide H 910 in the 80’s & 90’s along with our Lexicon & Delta Lab.This Eventide plugin does what we want.Cheers

Eventide® H910 Harmonizer - Dual Widerner Combo
This is the only version that's sounds like the real deal to me. I've been using this since 1980 and here's my Dual Widener Combo cofig: Left -1 / Right +1 and split em' 4 milliseconds apart anywhere from 10 to 40 depending on how deep you want it. Say Left 14 and Right 17. So that's 4 instances 2 -L / 2-R ... Double Wide! Nothing gets this sound without noticeable unwanted phasing. - Gilroy
C. Paschall
Cool effect!
Still exploring different uses for this guy but it's definitely been a fun new tool to add to the box.

Eventide H910
Just very exiting en get's you to a lot of creative idea's , love this plug in!!
R. Beld
Great vibey sound
Great sound to give an instant vibe. Would be great if there was a duo mode like Eventide's own version so you can do the pensado pitch trick 101 and 99 % at the same time.

great Effect
great effect plugin!
K. Sluiter
really useful plug in!
I bought the H910 originally because I had to recall a project that had them in their session. I now use it regularly on almost everything I do. Great for the micro pitch shift ( I use 2 plugs for this). Also great for de-tuning. Would be even more useful if keyboard responded to MIDI
C. Valentine
Oooh instant space
Have been using this in a bunch of ways. I drop it on keys and it’s instant space. I drop it on vocals and it’s a consistent solid octave sound. It’s soo pleasant to the ears. Thx for making this plug
