Description

The resonance filter is intended to emulate static resonances that are typically found in acoustic musical instruments. There are three non-overlapping frequency bands:

  • Low range - 60 to 300 Hertz
  • Medium range – 300 to 1k5 Hertz
  • High range - 1k5 to 7k5 Hertz

Emphasis (or Q) can be adjusted between 0.5 and 10, and each band has its own gain control. There are separate output level controls for the resonator (filter) and dry signal mix. The Polymoog’s filter could be switched between Low pass (LP), band pass (BP) and high pass (HP) modes. In addition, a band notch (BN) mode is available, that inverts the polarity of the middle frequency band in relation to the high and low bands. Note that the filter circuits emulate those in the Polymoog – warts and all
