Rescomb

Rescomb is a resonant Comb filter. A comb filter is a special kind of filter that creates multiple spaced notches. This module provides a CV input which is tuned (1V/octave) and a feedback parameter. When the feedback is high it will resonate, enhancing the frequencies of the comb.

This is the first module that I designed for VCV Rack. I really like comb filters, so I coded a very simple version in Vult; after playing with it and tweaking parameters I got this version. Rescomb is a weird effect, which in fact I use more as an instrument than as a filter.

Documentation

• V/Oct: this input will define the frequency of the filter/resonator.
• Tune: provides an offset for the V/OCT signal. When there is no V/OCT signal the reference is 0V.
• Comb: defines the type of comb filter. Depending on the V/OCT and the input, it will provide different sonic characteristics.
• Feedback: controls how much of the output is fed back into the filter. High feedback makes the comb resonate, enhancing its frequencies until it rings.
• Input: used to provide the input audio. Without a signal there will be no sound.
• Output: the output signal.
