Most eurorack modular systems will contain at least one filter module; one could view them as the stars of the eurorack show. Vermona twinVCFilter is one such star. A dual filter module with flexible routing and excellent audio properties, it covers a huge range of different applications with minimal effort. Features and routingEach filter section of twinVCFilter works as a low pass or high pass filter with a slope of 12 dB/octave or as a band pass filter with a slope of 6 dB/octave. Signals can be directed in three ways through the module: Serial: the incoming signal passes through both filter sections, one after the other. Parallel: the incoming signal passes through both filters at the same time. Dual: the filter sections act independently of one another, as if they were two individual filter modules. With these routings you can, for example, generate band passes or notches with variable slopes and different resonance settings or double the filter's slope. These are some of the more obvious combinations, but there's much more to discover. The convenient link feature allows you to couple the cutoffs and resonances of both filter sections for straightforward stereo use in dual mode. Mix sectionThe flexible signal routing is supplemented by the mix section. Here you can crossfade both filter sections manually or using control voltages. Seamless transitions from low pass to high pass filter are as easy as crossfading from half to doubled slope. Of course you can mix two individual signals or toggle between them by using a rectangle LFO modulation CV. ResonanceResonance is a key factor in the context of sound shaping and sound generation using a filter. Vermona therefore carefully trimmed twinVCFilter's resonance to be as musical and stable as possible. You can apply subtle, frequency-dependent emphasis to signals or tear them up into self-oscillation. The latter generates a solid sine wave, an excellent basis for percussive sounds, and potential cross-modulations significantly enhance these sound generation features. By the way, if you are missing a vibrato LFO in a patch, twinVCFilter can do that job, too. twinVCFilter offers a huge set of features to form impressive soundscapes. It can apply a subtle influence to signals or massively truncate frequencies and leaves nothing to be desired. Nevertheless, for those who need additional possibilities, Vermona also offers the tVCF-Extension companion module (sold separately). Physical specifications Size: 24hp Module depth: 40mm Power usage: 75mA @ +12V, 55mA @ -12V Power usage with tVCF-Extension (sold separately): 105mA @ +12V, 75mA @ -12V
