# MaskFilter : Ranged filter module using lowpass and highpass filters

## Description

The signal is first lowpassed and then highpassed to create a bandpass filter with independant lower and higher boundaries. The user can interpolate between two such filters.

## Sliders

> Filter 1 Limits :

>   Range of the first filter (min = highpass, max = lowpass)

> Filter 2 Limits :

>   Range of the second filter (min = highpass, max = lowpass)

> Mix :

>   Balance between filter 1 and filter 2

## Graph Only

> Overall Amplitude :

>   The amplitude curve applied on the total duration of the performance

## Popups & Toggles

> Number of Stages :

>   Amount of stacked biquad filters

> Balance :

>   Compression mode. Off, balanced with a fixed signal or balanced with the input source.

> Polyphony Voices :

>   Number of voices played simultaneously (polyphony), only available at initialization time

> Polyphony Spread :

>   Pitch variation between voices (chorus), only available at initialization time
