Der Quad VCA besteht aus vier analogen Verstärkerschaltungen, ihre Kennlinie kann zwischen linearer und exponentieller Charakteristik überblendet werden.

Kompakte Hüllkurve mit Loop-Funktion und VCA – Der Pico Modulator ist eine nur drei Teileinheiten breite Hüllkurve mit AD- und ASR-Modi.

Nach vielen verschiedenen Entwürfen ist der Digital VCA MKIII die endgültige Version des sehr umfangreichen VCA der Firma WMD. 

Der digitale VCA lässt das Signal wie ein normaler VCA durchlaufen, aber die CV und der Abschwächungspegel werden digital gesteuert. Dadurch ist es z.B. möglich, mit der Amplitudenänderung auf den Nulldurchgang zu warten, was zu klick freien Amplitudenänderungen führt. 

Javelin ist ein Modul, das im Grunde eine ADSR-Hüllkurve mit integrierten VCA darstellt. Es verfügt jedoch über einige Features, die das Modul zu einem expressiven Klangformungswerkzeug machen.

A-132-8 ist ein achtfacher VCA und in erster Linie für polyphone Anwendungen gedacht. 

Amps contains two precision linear VCAs that have been carefully designed to offer a wealth of flexibility and additional functionality. The front panel controls and signal normals allow these two VCAs to also be configured to function as: line level boosters, crossfaders, ring modulators, mixers, and much more.  They can also be chained together by way of an included cable to form larger, more complex systems.

The ‘MEGA-TANG’ is a 4-channel linear VCA and stereo mixer providing per input control over level, effect send, pan and muting. Designed for live use in mind with a simple & compact layout, the ‘MEGA-TANG’ builds on the clean and transparent sounding Tangle Quartet VCA by adding a stereo mix output, effect sends (mono send with a stereo return) which pair great with the MFX, manual panning, soft mute buttons with LED indicators and an expansion port for future expandability.

Erica Synths Black Quad VCA, despite its compact size, is designed in line with the Black Series Hi-Fi philosophy, our custom pre-emphasis – de-emphasis circuits preserve all the nuances of the original signal.

Snappy, classically analog envelopes with visually intuitive controls. Add a powerful, cv controllable cyclical gate generator,  integrated VCA, and trigger buttons —then double it—now you've got Tangrams.

The Erica Synths Black 3109 VCF/VCA is a lowpass filter and voltage-controlled amplifier combo built around the AS3109 VCF integrated circuit, a contemporary version of the IR3109 chip, found on vintage Roland synths such as the Jupiter series, Juno series and the SH-101.

The Dual Stereo Gate (DXG) music synthesizer module is a Dual Stereo Low Pass Gate and Mixer. It follows in the footsteps of the QMMG, Optomix, RxMx, DynaMix, and LxD. Unlike its predecessors, the DXG is specifically oriented around mixing stereo signals, making it an important addition to any system containing modules like XPO, QPAS, Morphagene, Mimeophon, and other stereo modules by Make Noise or others. 

Erica Synths Black LPG is our take on Lowpass Gate idea – it’s designed from scratch featuring 2nd order lowpass VCF (the original Buchla lowpass gate was 1st order VCF) and VCA combo with distinct resonance circuit on top.
