The Haible VC Resonator is an evolution of Jürgen Haible’s Resonator which was inspired by the Polymoog Resonator. As Jürgen said: “The Polymoog, an early polyphonic synthesiser, featured a 3-band “Resonator” section that allowed Formant-Filtering in addition to its dynamic Filters. Such a Resonator is a very useful feature for analogue synthesisers”. Each of the three (now overlapping) filter bands has a control for frequency, signal gain, and emphasis (resonance). The VC Resonator now not only adds VC control for each band, but also extends the ranges within which each frequency band can be set - adjacent bands can now overlap or even cross over, for instance the LOW and MED bands can now be set (or moved!) so that the LOW center frequency is higher than the MED frequency. Jürgen’s original Resonator (like the Polymoog) had a switch to select one of 3 basic modes, i.e. only one mode could be used at a time. The Haible VC Resonator now provids the same 3 modes as separate outputs so they can be used simultaneously, e.g. for further processing like crossfading.
