The Voltage Modular Miniverse Poly Filter is a 24dB/oct, low pass filter based on the famous transistor ladder filter. It's functionally identical to the standard mono version, but has up to 16-voice polyphony via its poly jacks.

If you're not familiar with how filters work, a low pass filter allows frequencies below the cutoff frequency setting to pass through, but blocks frequencies above the cutoff frequency.

Inputs, Outputs, and Controls

Cutoff Frequency- Sets the frequency where high-frequency attenuation begins.

Emphasis- More commonly referred to as "resonance," this emphasizes sound energy at and around the cutoff frequency by adding feedback from the filter's output back to its input. This is useful for creating commonly heard synth "wah" tones, particularly when the cutoff frequency is modulated with an envelope generator.

1V/Oct- This is a cutoff frequency modulation input intended to be used with keyboard CV inputs. It allows the cutoff frequency to follow or "track" notes played so that the relative brightness of notes increases as ascending notes are played. This allows the cutoff frequency to stay constant as the pitch frequency increases.

Amount of Contour- Applies modulation from the filter contour generator to the cutoff frequency. Turning it clockwise adds more modulation. Because filter mod is additive in nature, it's a good idea to dial the Cutoff Frequency knob back when using filter mod.

Poly Modulation jack and attenuverter - Used for externally modulating the cutoff frequency with a poly control signal. It's useful for adding filter sweeps or "wah wah" effects (or "weeow weeow," depending on the Emphasis knob position). The mod amount knobs are bipolar- center position is off; turning the knob to the right applies positive modulation, and turning to the left applies negative modulation. Note that each poly voice gets modulated individually with this mod input

Mono Modulation jack and attenuverter - Also used for externally modulating the cutoff frequency with a poly control signal. It's useful for adding filter sweeps or "wah wah" effects.The mod amount knobs are bipolar- center position is off; turning the knob to the right applies positive modulation, and turning to the left applies negative modulation. Unlike like the Poly Mod input, the Mono Mod input uses a single mono control signal that affects all poly voices equally.

Signal Input- The signal input for the filter. This usually would come from an oscillator wave output or a mixer.

Signal Output- The signal output of the filter.
