Cytomic has announced the release of a new VCV Rack module which delivers a highly detailed analog model of the classic cascade filter found in the early Prophet synthesizers which used the SSM2040 filter chips.
This model is based off the Discrete OTA schematic created by Jürgen Haible, with some extras added including multiple filters responses, and extra input and output saturation options.
It runs without internal oversampling over the full range of frequencies. Oversampling can be optionally done using VCV Racks sample rate settings, and is recommended for patches where large amounts of drive or stronger sounding high frequency resonance is required.
CF100 is available to purchase for $15 USD.
