Attenuate or Boost a frequency band

Introduced in v2.8

Options

amp:

The amplitude of the sound. Typically a value between 0 and 1. Higher amplitudes may be used, but won’t make the sound louder, they will just reduce the quality of all the sounds currently being played (due to compression.)

Default: 1
Must be zero or greater
May be changed whilst playing
Has slide options to shape changes

mix:

The amount (percentage) of FX present in the resulting sound represented as a value between 0 and 1. For example, a mix of 0 means that only the original sound is heard, a mix of 1 means that only the FX is heard (typically the default) and a mix of 0.5 means that half the original and half of the FX is heard.

Default: 1
Must be a value between 0 and 1 inclusively
May be changed whilst playing
Has slide options to shape changes

pre_mix:

The amount (percentage) of the original signal that is fed into the internal FX system as a value between 0 and 1. With a pre_mix: of 0 the FX is completely bypassed unlike a mix: of 0 where the internal FX is still being fed the original signal but the output of the FX is ignored. The difference between the two is subtle but important and is evident when the FX has a residual component such as echo or reverb. When switching mix: from 0 to 1, the residual component of the FX’s output from previous audio is present in the output signal. With pre_mix: there is no residual component of the previous audio in the output signal.

Default: 1
Must be zero or greater
May be changed whilst playing
Has slide options to shape changes

pre_amp:

Amplification applied to the input signal immediately before it is passed to the FX.

Default: 1
Must be zero or greater
May be changed whilst playing
Has slide options to shape changes

freq:

Centre frequency of the band in MIDI.

Default: 100
Must be greater than zero
May be changed whilst playing
Has slide options to shape changes

res:

Width of the band as a value between 0 and 1

Default: 0.6
Must be zero or greater,must be a value less than 1
May be changed whilst playing
Has slide options to shape changes

db:

Amount of boost or attenuation of the frequency band. A positive value boosts frequencies in the band, a negative value attenuates them.

Default: 0.6
May be changed whilst playing
