triangle~
Triangle/ramp wavetable
Description
triangle~ is a triangle/ramp wavetable with signal input to change phase offset of the peak value. The default lo/hi points are -1. and 1., but may be changed using the lo/hi messages.
Arguments
peak-value-phase-offset[float]
optional
Peak value phase offset, expressed as a fraction of a cycle, from 0 to 1.0. The default is 0.5 . A value of 0 produces a ramp waveform when the triangle~ object is driven by a phasor~, and a value of 1.0 produces a sawtooth waveform.
Attributes
hi[float]
Sets the maximum value of triangle~ for signal output. The default value is 1.0
lo[float]
Sets the minimum value of triangle~ for signal output. The default value is -1.0
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.
background[int]: 0
Adds or removes the object from the patcher's background layer. background 1 adds the object to the background layer, background 0 removes it. Objects in the background layer are shown behind all objects in the default foreground layer.
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'
'12'
'13'
'14'
'16'
'18'
'20'
'24'
'30'
'36'
'48'
'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]
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.
Messages
float
In left inlet: Any signal, float, or an input signal progressing from 0 to 1 is used to scan the triangle~ object's wavetable. The output of a phasor~ or some other audio signal can be used to control triangle~ as an oscillator, treating the contents of the wavetable as a repeating waveform.
In right inlet: Peak value phase offset, expressed as a fraction of a cycle, from 0 to 1.0. The default is 0.5. Scanning through the triangle~ object's wavetable using output of a phasor~ with a phase offset value of 0 produces a ramp waveform, and a phase offset of 1.0 produces a sawtooth waveform.
