ignoreclick[int]: 0
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile[symbol]
JS Painter File
patching_rect[4 floats]: 0. 0. 100. 0.
Sets the position and size of the object in the patcher window.
position[2 floats]
write-only
Sets the object's x and y position in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its size unchanged.
presentation[int]: 0
Sets whether an object belongs to the patcher's presentation.
presentation_rect[4 floats]: 0. 0. 0. 0.
Sets the x and y position and width and height of the object in the patcher's presentation, leaving its patching position unchanged.
rect[4 floats]
write-only
Sets the x and y position and width and height of the object in both patching and presentation modes (if the object belongs to its patcher's presentation).
size[2 floats]
write-only
Sets the object's width and height in both patching and presentation modes (if the object belongs to its patcher's presentation), leaving its position unchanged.
textcolor[4 floats]
Sets the color for the object's text in RGBA format.
textjustification[int]
Sets the justification for the object's text.
Possible values:
0 = 'left'
1 = 'center'
2 = 'right'
varname[symbol]
Sets the patcher's scripting name, which can be used to address the object by name in pattr, scripting messages to thispatcher, and the js object.

list
The filter coefficients can be provided as a
in the left or right inlet. The coefficients should be in sets of five, each set corresponding to a second-order section or biquad. The first five coefficients in the are used for the first second-order section in the series, the next five for the second, and so on.- filter-coefficients
[list]
bypass
The word
followed by a nonzero number will turn bypass mode on and cause the dry unfiltered signal to pass through to the object's outlet; followed by a 0 will output the filtered signal.- operational-flag
[int]
clear
Resets all coefficients and sample-memory to 0.
dictionary
The word filterdesign object dictionary (set via the attribute), will cause the cascade~ object to use the dictionary values for filter coefficients.
, followed by a symbol that references a named- dictionary-name
[symbol]
signal
In left inlet: Signal to be filtered. The signal is filtered by a series of two-pole two-zero (i.e. biquad) filters, often referred to as "second order sections".
zero
The word
followed by a nonzero number will cause the filtered signal to be muted; followed by a 0 will output the filtered signal (this will not prevent the unfiltered signal from appearing at the outlet when bypass mode is turned on).- operational-flag
[int]
Output
signal
The filtered signal.
