A unique vocal synthesizer.

Jussi

Vocal Synthesizer

A golden throat at your fingertips.

Jussi emulates male voice vowels in a unique way. Thanks to a set of powerful parameters 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, which makes it fun and easy to play using a MIDI keyboard.

Not without my friends

Jussi for macOS / Windows is only available for purchase via the Kanvas Synth Bundle, Instrument Bundle or Everything Bundle.

Features:

  • 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

Character

Drag the XY pad to alter tone intensity. The ’intense’ axis controls the formant’s Q value and the ’narrow’ axis the formant’s gain value.

2

Throat

This XY pad controls grain-factor (Y-axis) and the tonality/noise-factor (X-axis).

3

Three legato modes

Off: Like an ordinary polysynth. On: Normal legato mode (use XY pad to control). Hold: Smart polyphonic mode (see documentation for full info)

ADSR / Turn in & out

The ADSR controls the volume envelope of a triggered note with an option to slide the pitch (Turn in/out)
