phasor~

Generate sawtooth signals

Description

Use the phasor~ object to generate sawtooth waves suitable for sample-accurate control and timing tasks. For smoother sounding sawtooth generation, use the bandlimited saw~ object instead. The ramp rate can be set by frequency (Hz), or as an interval using the the tempo-relative Max time format syntax.

Examples

A repeating ramp is useful both at audio and at sub-audio frequencies

Arguments

initial-frequency [list]

Optional
Unitstime-value

Set the initial frequency in Hz, or as an interval using the the tempo-relative Max time format syntax.

Attributes

frequency [10 atoms]

Ramp rate or interval

lock [int]

'Scheduler in Overdrive' and 'in Audio Interrupt' must be enabled for accurate timing. These settings can be changed in 'Options'-> 'Audio Status'.

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] (default: 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'

hidden [int] (default: 0)

Toggles whether an object is hidden when the patcher is locked.

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] (default: 0)

Toggles whether an object ignores mouse clicks in a locked patcher.

patching_rect [4 floats] (default: 0. 0. 100. 0.)

Sets the position and size of the object in the patcher window.

position [2 floats]

g/s(set)

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] (default: 0)

Sets whether an object belongs to the patcher's presentation.

presentation_rect [4 floats] (default: 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]

g/s(set)

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]

g/s(set)

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 [float]

Sets the color for the object's text in RGBA format.

textjustification [int]

Text Justification

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

int

Arguments

frequency [int]
In left inlet: Set the frequency of the sawtooth waveform (Hz). If a signal is connected to this inlet, this message is ignored.

In right inlet: Set the phase of the waveform (from 0 to 1). Signal output continues from this phase.

float

Arguments

frequency [float]
In left inlet: Set the frequency of the sawtooth waveform (Hz). If a signal is connected to this inlet, this message is ignored.

In right inlet: Set the phase of the waveform (from 0 to 1). Signal output continues from this phase.

list

Arguments

transport/time-settings [list]
Set ramp interval in Max time format.

anything

Arguments

transport/time-settings [list]
Set ramp interval in Max time format.

signal

Set frequency in Hz

Output

signal

Sawtooth waveform that increases from 0 to 1 repeatedly at the specified frequency.
