App Description

Harmonizr is a vocal harmonizer offering a unique and fun user interface. Plug in a pair of headphones and sing a melody, tapping the correct key center buttons, and Harmonizr will follow, synthesizing up to three voices of automatic harmony in your own voice. Plug in a MIDI keyboard, or use the on-screen one, and you can sing harmony like Imogen Heap or Jacob Collier, matching every note you play. Harmonizr also can also be used as an Audio Unit (AUV3) extension within other apps, such as GarageBand, AUM, or Cubasis, and can be controlled by MIDI controller apps like SoundPrism.

I've been looking for an app like this for years! :D

Thank you so much. I couldn't be more excited. It's so much fun and I wish I'd found this app years sooner. I'd really like to be able to use this live and I'll be investigating ways to do that.Update: The developer is super responsive to feedback and I’m thrilled with the continual updates!

a solid little harmonizer!

Super easy to use out of the box (the tutorial when you first open the app is super helpful). I confirmed that it works with a USB midi input, and the ability to choose which mic to use is handy when you have cheap earphones with a low quality built-in mic. Thanks for making this!

Midi doesn’t work

I rarely write reviews but I got excited for this app. Only to find that it doesn’t work at all. When accessing bluetooth midi there’s no option to go back and try it for yourself. Also plugging in a midi controller by way of iRig pro, it still doesn’t work.Edit: It was a user error, when I first used this app, it did have a weird problem where you couldn’t hit the back button, that problem is now fixed. My user error was my keyboard was for some reason sending things to a different midi channel and the app was not registering the notes. I have an M-Audio Keystation 88, all I had to do was press the advance button and change the midi channel to 1 and the app works great now. Best harmonizer app out there thanks for being a nerd and keep going strong.
