Klevgränd Intros Jussi Vocal Synthesizer For iOS, Mac & Windows


Klevgränd has introduced Jussi – a new vocal synthesizer for iOS, Mac & Windows – designed to emulate the male voice.

They say that you can make Jussi sing anything from soft and airy choir-like vowels to hard and angry shouting. Formants are controlled by playing with different velocity.

Here’s the official video intro:


  • AUv3, works with AUv3 compatible hosts like Garageband, Cubasis, AUM etc.
  • ADSR with ”Turn-in” and ”Turn-out” option (Turn-in and Turn-out affects the pitch and maps it to attack and release)
  • Voice character XY pad (Intensity and Narrowness)
  • Legato mode (glides between notes and velocity levels)
  • Legato Hold mode (polyphonic legato when using a sustain controller, consult the documentation for more info)
  • Throat emulation XY pad (Grain and Tonality)
  • Built-in reverb

Jussi is available now for iOS and Mac/Windows.

Note: Jussi in stand-alone mode does not support IAA, Audiobus or MIDI. You can play it using the keys at the bottom, but that’s it. We recommend using Jussi with AUv3 compatible hosts.
