Q107 STATE VARIABLE FILTER

The Q107 Filter changes the harmonic content of signals to create new, interesting sounds. This removal of harmonics is the basis of subtractive synthesis. Both the cutoff frequency and the resonance (Q) of the filter can be controlled manually and/or controlled by another signal such as an envelope generator, oscillator, keyboard, etc. Control signals can be attenuated and inverted. Low Pass, Band Pass, Notch (Band Reject), and High Pass responses are provided simultaneously.
