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 extension within other apps, such as GarageBand, AUM, or Cubasis, and can be controlled by MIDI controller apps like SoundPrism.

What's new in version 1.3
* Fixed problem with MIDI button not turning off manual voices.
* Harmonizr now responds to MIDI program change messages, allowing it to follow your other MIDI gear from song to song on stage.
* Added new stereo modes: mono, and split, where the dry signal goes in channel one, and the harmony voices in channel 2.
* Cosmetic improvements to the interface.
