Haible VC Poly Resonator

The Haible VC Poly Resonator is Random*Source's Eurorack evolution of Jürgen Haible's Resonator, after the Polymoog's: three overlapping resonant filter bands, LOW, MED and HIGH, for formant filtering, each now under voltage control.

Key features

• Each band: its frequency, its GAIN (the input sent to it) and its EMPH (resonance, up to self-oscillation)
• Three CV inputs with attenuverters on the bands' frequencies
• Three outputs at once, LOW, BAND and HIGH, and a MODE switch adding the MED band to or subtracting it from the others at BAND (a notch)
• DRY adds the dry input to the processed signal
