Synapse Audio Rack Extensions

  • RM-1 is a virtual-analog ring modulator with a unique soft-saturation characteristic. Both an internal oscillator as well as mono and stereo side chains are available as a modulation source. Full CV control for all knobs is available on the backside of this rack extension.
  • AF-4 is a virtual-analog lowpass filter module, based on the well-known transistor ladder design. In order to obtain higest quality, this lowpass filter employs a topology-preserving, zero-delay feedback network with 4x oversampling, yielding results comparable to industrial circuit simulator.
  • DC-2 dual chorus offers a warm, sweeping stereo chorus effect based on a two-stage design with well-matched delay times.

The Rack Extensions are available to purchase at the Propellerhead Shop.

The AF-4 was updated to version 1.0.1:
This free update adds a sidechain for Filter FM on the backside, allowing to perform audio-rate filter frequency modulation. The sidechain can be used both with a mono or stereo source. Using a stereo source, the cutoff frequencies of the left and right channels can be independently controlled.
