Tre Modular - Replicant VCF

Tre Modular – Replicant VCF is a multimode -12 dB per octave second-order state variable filter that is based on one of the most famous synthesizers ever produced, Yamaha CS80.

Yamaha CS80 is known for its warm and mellow filter and Replicant VCF is designed to replicate the sound characteristics of this filter. If you want that classic CS80 sound in your Eurorack system, this is it.

Here is a jam showing off this module.

Features:

Cutoff – This module is a -12 dB per octave second-order filter. Because of that Replicant VCF cuts off frequencies in uniquely subtle and pleasant way.

Resonance – Replicant VCF is designed to be soft and mellow and resonance is a big part of that sound. This filter will not self oscillate nor have a loud and screechy resonance. Resonance of this filter is tame but distinct.

CV Control – Replicant VCF hac CV control over Cutoff and Resonance.

Outputs – This filter has High-pass, Band-pass and Low-pass outputs that can be used at the same time.

Here is a video with Replicant VCF filter sweeps. .

Module width: 10 HP
Module depth: 25mm
CV: -5v to +5v
Power Consumption: 33mA at +12V / 30mA at -12V

Here you can find two versions of the DIY assembly guide. One of them is more similar to CS80 where the filter output is lower than the signal input where you have to amplify the signal later in the signal chain. And the second version has filters output close to input signal levels.
