### 5/5 — Been my go to layered vocal vibes for years

*2025-11-14*

I’m going 5 stars because I have gotten so much use out of it over the years and it’s been good to me, just barely tho as it’s a big cpu hit, at this point a big update would really help, As of now I would probably recommend Bleass Voices over this, but I still use it often, and enjoy the limited presets.

### 3/5 — Was great but now

*2025-07-20*

I’ve enjoyed this app for years and previously considered it the best mobile vocoder app on the market. However, it has not been updated in years and is finally showing its age. Audio Unit no longer works in Loopy Pro on iOS 18.5. Full of static. I tried to set up the inter app audio, which works better, but still getting some static and the controls are unresponsive thus I can no longer edit or make new presets. Even VirSyn’s website is falling apart. I think, unfortunately, it’s time for this app to be retired.

### 5/5 — Solid Audio Unit

*2025-05-09*

Works well with GarageBand on iOS. I recommend using an app default preset or creating your own instead of changing parameters through GarageBand. Definitely recommend for anyone looking for solid vocal FX.

### 5/5 — A Load of Fun

*2020-05-08*

Excellent for fun and special effects. This is not a regular vocal harmony app. Must use earphones and external mic is best. Important to go into the effects section and fix the threshold. (>Dynamic processor > gate thresh around 30.)Better if the developer could make the threshold more accessible.

### 4/5 — Why not for Mac?

*2020-04-27*

I really need this for Mac!!!!

### 2/5 — Poor quality sound

*2020-01-29*

Lots of hype about this app. but found it very disappointing. Not asking much - just wanted a simple 3 party harmony that didn’t sound like the  Smurfs. 

However, can be used for experimental work.

### 4/5 — Very cool harmonizing effect

*2019-04-08*

I didn’t get it at first, but after checking out some presets realized it’s best not to use Shift and only transpose by Cents. Then the app started shining. I love having all kinds of fx, they broaden my imagination and spark creativity. Will definitely use this one on some voice tracks!

Some reviewers mentioned problems, I didn’t encounter any so far, I guess the developers took care of them.

Only downside I found is, that delay slider goes from 0 to 10sec, which I guess someone might need such a high value, but maybe you could add a “zoom” button which would make the slider range say, 0 - 100ms which is a good range for subtle delay effect. Or maybe make it accept typing values. It’s possible to dial in smaller values as it is, but just thought this would make the app even better.

### 5/5 — Luscious vocals and choirs made easy

*2018-08-07*

Need an ethereal spine-tingling choir? Lack of polyphonic vocals giving you the blues? Do you need to outdo Enya? Does your soul need a pick-me-up?

If you answered yes to any of these questions then you NEED this app! Honestly, I bought it on a whim not expecting much but boy was I happy I took the gamble. Anybody with functioning vocal cords can now create sublime choral soundscapes that truly recreate the sound of a living breathing choir.

Of course, it’ll create chaotic messes, barbershop harmonies, or basic studio effects commonly used for vocals. It’s the Swiss army knife of polyphonic vocal effects.

### 4/5 — Harmony 8  a good and effective instruction is all we need.

*2018-03-16*

It´s really neccessari selling an intruction from beginnig on
so I could work withit without faer and frustration. DO IT !

### 5/5 — Succeeds fantastically

*2018-01-22*

The interface is straightforward. Up to 8 voices which you can harmonise from -1 8ve to +1 8ve, and delay those harmonies independently. Different formants and different panning for each. Additional fx on top.
Personally I prefer to keep it natural sounding and modulate the pitch of voices from external MIDI sources. Incredible polyphonic results from this kind of experimentation, and the pitch shifted audio sounds very good. Naturally it works great also with monosynths etc. Very low latency on my iPad Pro.
