2. What is Klevgrand “Altitude”?
Altitude is a “vocal performance station” for singers, producers, and live performers. It delivers pitch correction, smart 3-voice harmony, a voice module you can play via MIDI, and advanced modulation – all in real time with ultra-low latency.
- Pitch correction: an engine with precision and sound quality on par with the industry’s leading tools
- Harmony: smart 3 voices that automatically follow the key
- Performance: turn your voice into an instrument you can play via MIDI
- Transformation: modulation ranging from subtle fluctuations to bold sound design
① High-quality, formant-aware pitch correction
At the core of Altitude is a solid pitch-correction engine. With formant-aware processing, it achieves fast, natural correction at ultra-low latency, keeping the sound musical even at extreme settings.
② Smart 3-voice harmony that follows the key
Up to three harmony voices sing in the correct key along with the lead, automatically avoiding unwanted dissonance so the chords always move musically. Each voice is processed individually for a more lifelike sound.
③ The “Play module” – perform your voice like an instrument
With the Play module, you can perform your own voice in real time with a MIDI keyboard, or arrange harmonies and melodies using MIDI data in your DAW. Control the mood with attack/release and the tone with width, doubler, and formant shift, with auto-correction supported as well.
④ Free, flexible modulation
Three independent modulators (up to 8 targets each) bring rhythmic movement and evolving textures to pitch, formant, harmony intervals, pan, volume, and more.
⑤ Natural, breathing vibrato
The vibrato module is designed to feel “alive.” The rate and depth vary per voice, so the voices fluctuate independently like real singers. A fade-in lets the vibrato rise naturally after a note is held.
⑥ A smart scale that stays musical
A note that works in a melody won’t always work in a harmony. Altitude’s scale system lets you turn the notes used by each harmony voice on or off individually, so the harmony always stays musical regardless of the melody’s movement.
Where it shines
- Hard-tune effect: the classic auto-tune / pitch-correction sound in an instant
- Live harmony: real-time 3 voices following a single input
- Thicken the lead: reinforce vocals with doubler, widener, and formant control
- Voice as instrument: play and arrange harmonies from a MIDI keyboard
- Transparent finishing: punch-in correction on specific notes only, without touching anything else
- Rhythmic textures: from subtle movement to experimental modulation
