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.
A unique vocal synthesizer.

Jussi
Vocal Synthesizer
A golden throat at your fingertips.
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.
Throat
This XY pad controls grain-factor (Y-axis) and the tonality/noise-factor (X-axis).
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)
