Altera Keys is a Kontakt-based software instrument that blends vintage inspiration with modern sound design. Rather than simply sampling classic keyboards, it recreates them from scratch, giving users greater control and tonal flexibility.

The result? Expressive electric pianos, punchy clav tones, smooth FM-style sounds, lush pads, and hybrid textures — all inside a single intuitive interface.

Whether you're producing pop, jazz, R&B, funk, cinematic scores, or ambient music, this instrument covers a wide sonic range.

20 Core Keyboard Models
Inspired by legendary electric pianos, clavs, FM synths, and digital classics — but redesigned using physical modeling and synthesis for enhanced realism and tweakability.

250+ Factory Presets
A massive preset library gives you instant access to polished sounds ready for production, from warm vintage keys to shimmering ambient textures.
