Product information "Metasonix RK6 Resonant Lowpass Filter"
Often customers ask me how to add some warmth to a digital signal or sample. I never really had an answer ready, because many devices saturate and distort nicely but lack in delivering on precisely this cliché. When it comes down to it, to make it sound warm all the ugly, cold and overexaturated parts of the signal should be eliminated. The beautiful parts should be captured and enhanced. The Metasonix RK6 closes this gap like a hero. Listen to the linked Video below to hear how it forms a round piece of music from of a cold, stiff wavetable sequence. The 2nd part of the video contains pure Metasonix DNA.
Conclusion: It is ugly but closes a crucial gap in your soul.

The RK6 is a Sallen-Key low-pass filter with an edge steepness of -12 dB per octave. It features a 17JK8 dual triode. The tube is operated more conservatively than usual to ensure maximum lifetime. Incoming audio material can be leveled before reaching the actual filter. Cutoff and resonance are adjustable via potentiometers. In addition, it is possible to influence both parameters via control voltages. The cutoff CV input accepts signals in the range of 0 V to +3 V. It roughly follows the Hz/v standard. The resonance behavior varies depending on the cutoff setting.
As Eric Barbour lost his day-job by the late 1990s, he decided to apply his vast knowledge and expertise in vacuum tubes to make noise making instruments. By now he has earned a reputation of creating some of the most nasty sounding instruments. Not for the faint of heart.
