Klevgrand Altitude looks like the kind of vocal plugin that can save you from building a chain out of three or four separate tools. It brings pitch correction, harmonies, MIDI playability, modulation, doubling, widening, and formant shaping into one place, with Klevgrand pitching it for both studio and live use.
What Altitude Actually Does
Altitude combines formant-aware pitch correction, three smart harmony voices, a MIDI-playable voice module, and three independent modulators inside one interface. Klevgrand also says it runs in real time with a dedicated zero-latency mode, which is the detail that matters most if you want to track or perform without the vocal feeling disconnected from the singer.
That package covers a lot of ground. You can lock a vocal into key, stack harmonies that avoid dissonant intervals, thicken the lead with a doubler and widener, and then animate the whole thing by routing modulation to pitch, formants, harmony intervals, panning, and level. The scale system also supports MIDI control and micro-tuning, so it is not limited to a simple set-and-forget correction workflow.
What It Can Do For You
If you sing live, Klevgrand Altitude looks built for the obvious pain point: keeping tuning and harmonies under control without turning the performance into a latency nightmare. The zero-latency mode, smart harmony voices, and MIDI-controlled scale handling all point to stage use where songs move fast and setup time is short.
If you produce in the box, the Play module is probably the bigger hook. You can perform vocal lines from a MIDI keyboard or sequence them in the DAW, then shape attack, release, width, doubling, and formant behavior as part of the arrangement. That makes Altitude useful not just for fixing vocals, but for writing with them.
If you make electronic, pop, hyperpop, or left-field vocal music, the modulation side is where things get more interesting. Three modulators with up to eight targets each, plus a step editor with up to 16 steps, means the plugin can go from gentle motion to deliberately artificial textures without sending you into a second or third effects chain.
If you mostly want cleaner vocals, there is still a practical angle here. Punch-in correction lets you fix specific notes rather than ironing the whole performance flat, and the built-in vibrato, doubler, widener, and formant tools mean there is a decent chance you can stay in one plugin longer before reaching for extras.
Klevgrand Context
Klevgrand has been circling vocal and playable sound design ideas for a while, so Altitude does not feel like a random detour. ANR readers might remember Pipa – A Singing Synth With A Twist, which explored the company’s more synthetic take on the voice, or the older Klevgränd Jussi – A New Singing Synth For iOS And VST Users post.
That history matters because Altitude looks less like a generic vocal utility and more like the point where Klevgrand’s interest in voice, playability, and streamlined interfaces finally meet in one product. Needless to say, that makes it more interesting than yet another “pro vocal chain” with a few safe presets and a shiny skin.
