more of its distortion internally.

stages: a hard diode clipper on the input and
a soft saturation on the output.
4 = 'Membrane Resonator'

modes of a circular membrane. The size,
resonance, and high frequency damping of
the membrane can be altered.

Phaser
)
A six stage delayless inverted-feedback phaser with
variable feedback and notch spacing.
8 = 'Plate Resonator'
(
Plate Resonator
)
A modal resonator tuned to the first 32
modes of a rectangular plate. The size,
resonance, and dimension-ratio of the plate
can be altered.
9 = 'Redux'
(
Redux
)
A resampler and bitcrusher with variable samplerate,
quantization, and control over the amount of
resampling artifacts.
10 = 'SVF 12dB'
(
SVF (12dB)
)
A 12dB per octave state variable filter which
can morph through these configurations:
low-pass, band-pass, high-pass, notch.
11 = 'SVF 24dB'
(
SVF (24dB)
)
A 24dB per octave state variable filter which
can morph through these configurations:
low-pass, band-pass, high-pass, notch.
12 = 'LP Switched Res'
(
Low-pass Switched Resistor
)
A low-pass filter where resistors are
replaced with fast switches to create
downsampling artifacts.
13 = 'Vowel'
(
Vowel
)
A formant filter with vowel characteristics.
Common Box Attributes
annotation[symbol]
Sets the text that will be displayed in the Clue window when the user moves the mouse over the object.

color[4 floats]
Sets the color for the object box outline.
fontface[int]
Sets the type style used by the object. The options are:
plain
bold
italic
bold italic
Possible values:
0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'
fontname[symbol]
Sets the object's font.
fontsize[float]
Sets the object's font size (in points).
Possible values:
'8'
'9'
'10'
'11'

'64'
'72'
hint[symbol]
Sets the text that will be displayed in as a pop-up hint when the user moves the mouse over the object in a locked patcher.
ignoreclick[int]: 0
Toggles whether an object ignores mouse clicks in a locked patcher.
jspainterfile[symbol]
You can override the default appearance of a user interface object by assigning a JavaScript file with code for painting the object. The file must be in the search path.

Aliases: patching_position, patching_size
Sets the position and size of the object in the patcher window.
position[2 floats]
write-only
