Method Details

patchs

public ArrayList<Patch> patchs()

patch

public Patch patch(int index)

Parameters:

index - index of patch as stored in patch(). note that this not to be confused with the final field .ID in Patch which refers to a unique ID for each patch ever created.

Returns:

patch stored at index

output_signal

public Signal output_signal()

callback method that accumulates audio signals from child patchs and if applicable maps mono signals into stereo space. this method can be overridden to implement custom behavior, however, if doing so make sure to also call Signal output_signal_update() to collect signals from child patchs.

Specified by:

output_signal in interface DSPNodeOutputSignal

Returns:

signal of this patch

output_signal_update

public Signal output_signal_update()

accumulates signals from child patchs and if applicable maps mono signals into stereo space.

Returns:

accumulated signal of child patches

pan

public Pan pan()

get_volume

public float get_volume()

Returns:

patch volume with 0.0 being no output and 1.0 being 100%

set_volume

public void set_volume(float volume)

volume of patch with 0.0 being no output and 1.0 being 100% of the signal output. note, that this value is interpreted by parent Patchs.

Parameters:

volume - patch volume with 0.0 being no output and 1.0 being 100%
