Waldorf Music STVC Keyboard – 49-Key String Synthesizer with Vocoder

OVERVIEW

The Waldorf Music STVC Keyboard brings the unmistakable sound of vintage string machines into the modern era, combining lush ensemble textures with advanced synthesis and vocoder capabilities. At its core is a fully polyphonic string section built around an oscillator bank with octave dividers, followed by a detailed mixer, EQ shaping, and the signature ensemble effect. A single registration control allows seamless morphing between classic tonal characteristics such as violin, viola, cello, brass, organ, and choir – delivering rich, evolving textures with minimal effort.

Complementing the string engine is a versatile 16-voice polyphonic solo synthesizer, capable of both supporting and leading performances. With its intuitive Tone control, users can quickly shape expressive lead sounds or blend them alongside the string section for layered textures. The integrated vocoder replaces the EQ stage with a detailed filter bank that models the human vocal tract, enabling highly intelligible speech synthesis, singing effects, and creative vocal manipulation. Features such as formant shifting and adjustable oscillator jitter allow for unique tonal variations – from subtle vocal colouration to dramatic transformations.

Designed with performance in mind, the STVC Keyboard includes a Freeze function for capturing and looping vocal fragments, along with a Tweak system that enables deep parameter modulation and customisation. Three simultaneous effects – Animate, Phaser, and Reverb – add movement, depth, and space to your sound. Complete with a high-quality gooseneck microphone and a responsive 49-key keyboard with velocity and aftertouch, the STVC is a versatile instrument that excels in both studio production and live performance environments.
