poke~

Write sample values to a buffer by index

Description

poke~ allows you to write samples into a buffer~ at sample locations specified by a signal.

Arguments

buffer-object-name[symbol]
optional

Obligatory. Names the buffer~ where poke~ will write its incoming samples.

channel-number[int]
optional

Sets the channel number of a multichannel buffer~ where the samples will be written. The default channel is 1.

Attributes

Common Box Attributes

Below is a list of attributes shared by all objects. If you want to change one of these attributes for an object based on the object box, you need to place the word sendbox in front of the attribute name, or use the object's Inspector.

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'

hidden[int]: 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]: 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.

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

int

In left inlet: Converted to float.

In middle inlet: Sets the sample index for writing subsequent sample values coming in the left inlet. If there is a signal connected to this inlet, a float is ignored.

Arguments:
  • value/sample-index [int]

float

Like the peek~ object, poke~ can write float values into a buffer~. Note, however, that the left two inlets are reversed on the poke~ object compared to the peek~ object.

In left inlet: Sets the value to be written into the buffer~ at the specified sample index. If the sample index is not -1 , the value is written.

In middle inlet: Converted to int .

In right inlet: Converted to int .

Arguments:
  • value/sample-index/channel-number [float]

list

In left inlet: A list of two or more values will write the first value at the sample index specified by the second value. If a third value is present, it specifies the audio channel within the buffer~ for writing the sample value.

Arguments:
  • value, sample-index, and channel-number [list]

(mouse)

Double-clicking on poke~ opens an editing window where you can view the contents of its associated buffer~ object.

set

The word set , followed by the name of a buffer~, changes the buffer~ where poke~ will write its incoming samples.

Arguments:
  • buffer-object-name [symbol]

signal

In left inlet: Signal values you want to write into a buffer~.

In middle inlet: The sample index where values from the signal in the left inlet will be written. If the signal coming into the middle inlet has a value of -1, no samples are written.
