Harmony Eight by VirSyn

Today VirSyn released an impressive looking polyphonic pitch-shifting delay effect, Harmony Eight! It may help to think of it as a kind of vocoder, but it is more than that as you can see in the demo video below.

Correction: When I said polyphonic I meant the resulting output, not the input. This was confusing, and in hindsight, dumb of me. The iTunes description now points out that it "needs to detect a single pitch" to work correctly. Thanks to reader Simon for pointing out the new iTunes disclaimer.

Harmony Eight iTunes Description:

### Introductory offer for a limited time ###

Up to eight pitch shifted voices are created from vocal input or monophonic instruments.

Position each voice in space ( left and right / front and back )

Modify the voice character from male to female and vice versa.

Pitch shift each voice in the range of +/- one octave with preserving of formants for natural sound.

Applying separate feedback delays on each voice creates complex rhythmical patterns.


• 8 Voice Pitch Shifter with formant correction
• 8 Independent delay lines with optional sync
• Spatial voice positioning
• Parametric Equalizer
• Integrated Compressor/Limiter/Noise Gate
• Ensemble effect
• Reverb effect
• AudioUnit for AUv3 compatible hosts.
• Inter-app audio compatible effect.
• Audiobus 2 compatible with state saving.
• Low latency live usage with mic and headphones.
• Audio recorder

My immediate reaction is: This is not what is needed.

These fixed interval pitch shifters are only useful for very specific things, like octaves and rhythmic stuff. For musical phrases, you would have to use it on really simple things in order for it to stay in the key.

What they SHOULD have done was made an intelligent pitch-shifting delay-- with custom scales. I would have bought that.

This is a hard pass.

In the meantime, we continue to wait for the intelligent pitch-shifter/harmonizer. I actually think VirSyn are the ones to do it, but so far they haven't.
Today the developer added a disclaimer to the Apple Store description:

"Please note that Harmony Eight is not suited for polyphonic sounds like Guitar or Piano because this App needs to detect a single pitch for working as expected."

Thanks for pointing that out, Simon!
I think I might get this - it looks like a very cool app!

For version 1.0 must warn people that the app is suited best for Vocals ONLY.
You could feed other monophonic instruments but only for experimental sounds .

Maybe another update in the description would avoid negative reviews.

My kind of toy!

There were a few grumbles about 'audio quality in certain situations' on the AudioBus forum.

The developer released an update today with "Bugfix: Tempo setting was broken".

Nice to have responsive developers like this.

Good fun. But I'd like a few more presets. He says, lazily!
