## 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.

## Review summary

Reviewers praise Harmonizr for its high-quality vocal harmonies and professional sound, especially with a good mic. It’s easy to use out of the box, with a helpful tutorial, and offers deep customization via presets and MIDI/audio control. It also has strong hardware/DAW integration (USB MIDI, iRig, Audiobus) and a responsive developer who updates the app. Recurrent downsides include limited in-app help, incomplete inter-app workflow (GarageBand/BandLab) for recording, and MIDI control gaps (no easy bypass or CC mapping). A few users report occasional setup issues.
