Waldorf introduces the STVC String Synthesizer with Vocoder

The STVC features a metal housing, making it ideal for use both in the studio and onstage. The 49 keys are aftertouch and velocity sensitive and can be easily transposed +/- 2 octaves with a dedicated switch. Besides the multitude of knobs, switches and backlit buttons that allow a fast and easy access to sound generation, a small display provides more detailed insight and editing possibilities.

 Tender Strings

The full polyphonic strings section starts with an octave divider-based oscillator. Afterwards, the signal goes into a complex mixer, followed by an EQ and an ensemble effect, like on many string machines from the 1970s. Different registrations for Violin, Viola, Cello, Brass, Organ, Choir, and more can be chosen with a single pot. This way the STVC offers a wide array of string sounds that can be used not only as background pads in a production, but also in many other ways.

 Solo Please

Apart from the strings section there is a 16-voice synthesizer to complement the string sounds. Even though the solo synthesizer was conceived as an addition to the strings, it provides enough energy to cut through a mix by itself and take over center stage.

 Language Wizard

The vocoder replaces the EQ of the strings section with a filter bank, which modulates the vocal signal depending on the speech fed to it. The STVC includes a high-end 44cm gooseneck microphone which can be attached directly onto the front panel. The fully polyphonic oscillator bank is used as carrier signal and can produce very intelligible speech or vocals. Formants can be modified in such a way that any female voice can be transformed into a male voice and vice versa. The adjustable jitter can make the voice sound hoarse or raspy, or even transform it into a whisper. The Solo section can be played through the vocoder or used in parallel.

 Shaping Possibilities

The Freeze button allows short phrases to be frozen and repeated by the vocoder when a given key is pressed. The playback speed is adjustable, and negative values make the vocal part play backwards. Formants and jitter can be modified at will, too.

The new Tweak function allows modifying specific sound settings in detail, to change the solo cutoff frequency or the chorus LFO rate, for instance. It is built like a classic modulation matrix, but also allows changing implicit settings with fix values or offsets.


The three built-in effects of the STVC can be used simultaneously: Animate modulates the string or vocoder registration; Phaser is an indispensable ingredient of any string machine worthy of the name, and the high-quality Hall with adjustable room size can be mixed with the output signal.
