Fusion VCA/Waveshaper/Ringmodulator

The Erica Synths Fusion VCA/Waveshaper/Ringmodulator is a highly versatile and unconventional sound processing module for Eurorack systems. As a key component of the Fusion series, this module leverages the unique sonic characteristics of vacuum tubes to provide a wide range of dynamic control and timbral manipulation options. It is not a typical VCA, but rather a complex sound-shaping tool that encourages experimentation and can take your sounds into new and uncharted territory. From subtle tube warmth and saturation to aggressive waveshaping and metallic ring modulation, this module is a powerful addition to any modular setup.

The Fusion VCA/Waveshaper/Ringmodulator is based on two miniature pentode vacuum tubes, which are at the heart of its distinctive sound. It can function as a VCA, but its true power lies in its more advanced features. The module has two CV inputs that are not mixed but instead control different grid voltages of the tubes, allowing for complex and non-linear amplitude modulation. A manual bias control lets you set the initial gain of the VCA, and a manual overdrive control allows you to dial in the desired amount of tube saturation. The module also features a built-in ring modulator for creating classic metallic and dissonant textures. When used in conjunction with the VCA and waveshaping capabilities, the ring modulator becomes an even more powerful tool for sound design. An input crossfader allows you to blend between two different audio sources, and a direct switch for a more conventional VCA mode provides added flexibility. With its unique tube-based design and multifaceted functionality, the Fusion VCA/Waveshaper/Ringmodulator is a truly inspiring sound-shaping tool.
