Verbos Dual Four Pole Filter

Resurrecting some of the characteristic charm found in tape music studios during the 1960s, the Dual Four Pole Filter by Verbos Electronics is based around an all-discrete transistor filter, lending a distinct sound to both of the module’s filters. The left side is a high-pass filter with two cutoff CV inputs (each with their own dedicated attenuator and voltage-controlled resonance). The right side is a low-pass filter with the same dedicated controls. Though neither filter self-oscillates, the sound it is capable of producing is not easily found elsewhere.

Dual Four Pole | Filter Overview & CV
The Dual Four Pole (as the name suggests) has two, four pole filters - one high pass and one low pass which are capable of very subtle and smooth filtering. In this patch, we demonstrate the manual panel controls and apply CV from the Voltage Multistage and Multi-Envelope to all inputs provided.
