gen~
Generate native audio signal processing routines
Description
The gen~ object turns an embedded Gen patcher into signal processing routines of optimized native machine code. The Gen patcher can be built from a wide set of low-level Gen operator objects as well as embedded code expressions.
Arguments
patcher-name[symbol]
optional
The first argument, if given, specifies the name of a .gendsp patcher to be loaded which already exists and is in the Max search path. The patcher can also be specified using the gen attribute. If no Gen patcher is specified by argument or gen attribute, an embedded Gen patcher is created instead.
Attributes
autoexport[int]: 1
Automatically export code on edit. Equivalent to sending the exportcode message every time an edit is made. Please note that in order for this to work properly, the following must be true: audio must be on, a previous manual export must have occurred, and a valid value for the exportfolder attribute must be set.
cpu[float]
read-only
Reports cpu usage as a fraction of available compute time, if cpumeasure is enabled.
cpumeasure[int]: 0
CPU monitoring must be enabled for cpu to work.
dumpoutlet[int]: 0
Enables an additional "dump" outlet for diagnostics, such as reading the cpu attribute.
exportfolder[symbol]:
Folder to export code into. Used by the exportcode message to determine what directory to write source files into.
exportname[symbol]:
Export Filename
exportnotifier[symbol]:
Receive object name to receive export notification
exportscript[symbol]:
Post export script
exportscriptargs[symbol]:
Post export script arguments
gen[symbol]:
Gen patcher name to load from disk
nocache[int]: 0
The nocache attribute, with an argument of 1, recompiles the Gen patcher regardless of whether another instance of Gen has already compiled it. When set to 0 (default), Gen caches previous compiles to save on load time.
poll[int]: 0
Enable attribute polling
title[symbol]
Set patcher title.
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]
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.
