Erica Synths Debuts its Black Ring-Xfade Sound Shaping Module

New Eurorack module consists of two unconventional ringmodulators / waveshapers and a crossfader that works with both CV and a VCA

Riga, Latvia, May 14, 2021 — Erica Synths announces its Black Ring-Xfade sound shaping module. The Black Ring-Xfade is an extremely versatile module for sound shaping, and consists of two unconventional ringmodulators/waveshapers, and a crossfader that works both for audio and CV and a VCA.

Unlike a conventional ringmodulator that only works with a signal present on both signal and carrier inputs, the Black Ring-Xfade passes through the signal without alteration if no carrier is present. However, low level signals on the carrier input can result in unique waveshaping. Add the crossfader between two ringmodulators — or for external signals — topped up with the VCA, and you have an amplitude modulation powerplant for your modular system.
