Make the incoming signal sound more spacious or distant as if it were played in a large room or cave. Similar to reverb but with a more spacious feel.

Introduced in v2.9

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: 0.4
Must be a value between 0 and 1 inclusively
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

spread:

Stereo spread. Amount of stereo spread the reverb has over the left and right channels. A value of 0 means no spread at all - left and right stereo values of the incoming signal are preserved. A value of 1 means full spread - the left and right channels are fully mixed within the reverb - bleeding into each other.

Default: 0.5
Must be a value between 0 and 1 inclusively
May be changed whilst playing
Has slide options to shape changes

damp:

High frequency rolloff. 0 is no damping (the reverb will ring out more) and 1 dampens the reverb signal completely

Default: 0.5
Must be a value between 0 and 1 inclusively
May be changed whilst playing
Has slide options to shape changes

pre_damp:

High frequency rolloff of input signal. 0 is no damping (the reverb will ring out more) and 1 dampens the reverb signal completely

Default: 0.5
Must be a value between 0 and 1 inclusively
May be changed whilst playing
Has slide options to shape changes

dry:

Amount of original dry signal present in the effect. This is distinct from mix.

Default: 1
Must be a value greater than or equal to 0
May be changed whilst playing
Has slide options to shape changes

room:

The room size in squared metres

Default: 10
Must be a value greater than or equal to 0
May be changed whilst playing

release:

Time for reverberation to complete in seconds

Default: 3
Must be a value greater than 0
May be changed whilst playing

ref_level:

Reflection level

Default: 0.7
Must be a value greater than or equal to 0
May be changed whilst playing

tail_level:

Tail level amount

Default: 0.5
Must be a value greater than or equal to 0
May be changed whilst playing

Slide Options

Any parameter that is slidable has three additional options named _slide, _slide_curve, and _slide_shape. For example, 'amp' is slidable, so you can also set amp_slide, amp_slide_curve, and amp_slide_shape with the following effects:

_slide:

Amount of time (in beats) for the parameter value to change. A long parameter_slide value means that the parameter takes a long time to slide from the previous value to the new value. A parameter_slide of 0 means that the parameter instantly changes to the new value.

Default: 0

_slide_shape:

Shape of curve. 0: step, 1: linear, 3: sine, 4: welch, 5: custom (use *_slide_curve: opt e.g. amp_slide_curve:), 6: squared, 7: cubed.

Default: 5

_slide_curve:

Shape of the slide curve (only honoured if slide shape is 5). 0 means linear and positive and negative numbers curve the segment up and down respectively.

Default: 0
