In this video we explore what was once one of the most coveted filters in the history of EURORACK. Whimsical Raps MANNEQUINS Three Sisters Linked Filters. What a mouthful.

In a nutshell, it is a great sounding filter with the only quirk being that it can get easily overloaded or have deep resonance in unexpected spots, which can be a good or a bad thing depending on what one is after. It definitely has more character than the two other stand alone filters I own, Bastl Ikarie and Mutable Ripples V2.

Quoting the most clear description of what it does:

THREE SISTERS
LINKED FILTERS FOR SPECTRAL MIXING AND RESONANT SCULPTING
Three Sisters related to, and reflections of, one another. Together carving spectral spaces, reorganising and deconstructing tones. A kaleidoscopic lens into your world of sound.

Three filters, of switched modes, independently input and returned. FREQ pushes all three, traveling together, while SPAN repels forcing sources into isolation. ALL ins and outs are global, cohesive, united. Formant passes three bands, 4 poles a piece, sounding vowels with wide SPAN. All are transformed beyond with QUALITY – more for resonant emphasis into ringing harmonics – less for the antifilter, whiteonwhite, fade to drysimulacrum.

With high QUALITY the Sisters form a choir, singing in pure tones – three tones, in harmony or discord. CENTRE maintains the alto counterpoint, greater than its sum, driving SPAN to introduce a cacophony of FM bell tones and hyperstereo effects. Psychoacoustics of parallel bands will eerily disconcert when spatialized effectively.

Variable shelves and razorband response can be designed with smart selfpatches. Equalizing peaks and processheavy notches are only a cable away. Swim to the edge, climb the ladder, and dive back in.
