What Jussi does
The instrument uses velocity to shape its formants, so different playing strength moves the vowel-like tone. The Character XY pad sets tone intensity, with the intense axis controlling the formant Q and the narrow axis controlling formant gain. A second pad, Throat, controls the grain factor on its Y axis and the tonality or noise factor on its X axis.
Legato is offered in three modes. The volume envelope is an ADSR with a Turn-in Turn-out option that affects pitch, attack and release. Jussi is available as VST2, AU and AAX for Windows and macOS, and the release circulates as a crack for the Windows and macOS builds, packed as .rar and .iso, with a torrent or magnet link often paired with the plugin name and keygen or serial key searches.
Key features
- Character XY pad. Dragging the Character pad changes tone intensity, with the intense axis setting formant Q and the narrow axis setting formant gain.
- Throat XY pad. Throat sets the grain factor on the Y axis and the tonality or noise factor on the X axis.
- Velocity-driven formants. Formants are controlled by playing at different velocity levels, which keeps the timbre responsive to touch.
- Three legato modes. Off gives ordinary polysynth behavior, the normal legato mode glides between notes, and Hold provides polyphonic legato with a sustain controller.
- ADSR with Turn-in Turn-out. The volume envelope is triggered per note, and the Turn-in Turn-out option affects pitch as well as attack and release.
