Erica Synths Debuts Sound Shaping Module

Erica Synths has introduced its Black Ring-Xfade Sound Shaping Module. They tell us that this new Eurorack module 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.

A spokesperson told us, "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."


  • Dual ringmodulator/waveshaper
  • Carrier level adjustment
  • Voltage controlled crossfader
  • Manual and CV control over crossfade
  • Selectable AC (audio) or DC (control voltage) coupling
  • VCA with selectable bias


Pricing and Availability:
The Black Ring-Xfade is available now at the Erica Synths webshop and through authorized dealers, and is and priced at €150 (VAT excl.) and $189 USD.
