Synapse Audio updates Analog Filter AF-4 to v1.0.1

Synapse Audio has updated its Rack Extension, Analog Filter AF-4, 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.
