Jussi

Jussi by Klevgrand is a vocal synthesizer that turns MIDI notes into expressive male vowel sounds. Its range stretches from gentle, breathy choir textures to forceful, shout-like tones, making it useful for atmospheric layers, vocal melodies and bold synthetic hooks. Playing with different velocities changes the formants, giving keyboard performances a direct way to shape the voice. Two XY pads let you adjust vocal intensity and narrowness, then explore grainy, tonal or noisier throat characteristics. An ADSR envelope shapes each note, while Turn-in and Turn-out add pitch movement tied to the attack and release. Choose standard polyphonic playing, legato glides between notes and velocity levels, or sustain-controlled polyphonic Legato Hold. Built-in reverb adds space around the sound. Jussi suits producers who want playable vocal character without relying on recorded phrases.
