The twinVCFilter is a dual filter module with flexible routing and excellent audio properties.

Features and Routing Each filter section of the twinVCFilter functions as a low-pass or high-pass filter with a slope of 12 dB/octave, or as a band-pass filter with 6 dB/octave.

Signals can be routed through the module in three ways:

• serial: The incoming signal passes through both filter sections in sequence.
• dual: The filter sections operate completely independently, as if they were two separate filter modules.
• parallel: The incoming signal passes through both filters simultaneously.

With these routings you can for example generate bandpasses or notches with variable slopes and different resonance settings, or double the filter’s slope. These are the more obvious combinations, but there is much more to explore.

The convenient link feature allows you to couple the cutoff and resonance of both filter sections for straightforward stereo use in dual mode. Mix section The flexible signal routing is complemented by the mix section, where you can crossfade both filter sections manually or via control voltages.

Seamless transitions from low-pass to high-pass filter are as easy as crossfading from half to double slope. Of course, you can mix two completely individual signals or toggle between them using rectangle LFO modulation.

Resonance is a key factor in sound shaping and sound generation using a filter. Therefore, we carefully tuned the twinVCFilter’s resonance to be as musical and stable as possible. You can apply subtle frequency-dependent emphasis to signals or push them into self-oscillation. The latter produces a solid sine wave, which is an excellent base for percussive sounds.

Possible cross-modulations significantly enhance the sound generation features. By the way: If you are missing a vibrato LFO in a patch, the twinVCFilter can perform that function. The twinVCFilter offers a vast set of features to create impressive soundscapes. It can subtly influence signals or drastically cut frequencies. It leaves nothing to be desired. Nevertheless, for those who need additional options, we specially designed the tVCF-Extension module.
