Altitude

Altitude by Klevgrand is a real-time vocal performance station that combines formant-aware pitch correction, up to three smart harmony voices, and MIDI-playable voice instrument capabilities. Its low-latency pitch engine delivers natural, musical correction even at extreme settings, while harmonies automatically follow your lead and skip dissonant intervals for chords that always move musically. A doubler with two modes and a widener fatten the sound, and optional vibrato, humanizer, and auto-formant correction add organic character. The Play module lets you perform your voice like an instrument via MIDI keyboard or DAW data, with attack, release, width, and formant shifting for tonal control. Ideal for singers, producers, and live performers, Altitude suits genres from pop and EDM to experimental sound design. It runs on Windows and macOS in FL Studio, Ableton Live, Logic Pro, and other major DAWs.
