# UpDistoRes : Arctangent distortion module with upsampling and resonant lowpass filter

## Description

This module applies an arctangent distortion on an upsampled signal and pass the result through a 24dB/oct lowpass resonant filter.

## Sliders

> Pre-Filter Freq :

>   Center frequency of the filter applied before distortion

> Pre-Filter Q :

>   Q factor of the filter applied before distortion

> Pre-Gain :

>   Gain control applied before the distortion

> Drive :

>   Amount of distortion applied on the signal

> Lowpass Freq :

>   Cutoff frequency of the 24dB/oct lowpass filter applied after distortion

> Lowpass Res :

>   Resonance factor of the 24dB/oct lowpass filter applied after distortion

> Dry / Wet :

>   Mix between the original signal and the degraded signal

## Graph Only

> Overall Amplitude :

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

## Popups & Toggles

> Pre Filter Type :

>   Type of filter used before distortion

> Balance :

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

> Upsampling :

>   The resampling factor. The process will be applied with a virtual sampling rate of the current sampling rate times this factor.

> Interpolation :

>   Defines the FIR lowpass kernel length used for interpolation and decimation. The kernel length will be the upsampling factor times this value.

> 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
