mc.evolve~
Generate a periodic multichannel function from breakpoint ranges
Description
The mc.evolve~ object accepts breakpoints consisting of ranges where both the domain and range go from 0 to 1. It maps this set of ranges across the space of a multichannel output signal, where the first channel in the output signal outputs the low end of the range and the last channel outputs the high end. Connect a phasor~ or another time-varying signal to mc.evolve~ to drive the output.
Arguments
chans[int]
optional
Sets the number of channels in the output multichannel signal.
Attributes
chans[int]: 4
The number of output channels can be reduced from the value specified by the object's argument; in this case extra outputs will be zero and the output range will be spread over a smaller number of channels.
inclusive[int]: 1
Determines how endpoint values are taken into account when calculating values for each output channel.
Possible values:
0 = 'Neither'
(
Ignore Endpoints
)
Use neither the low or high endpoint values when calculating mc channel values.
1 = 'Both'
(
Use Endpoints
)
Use the low enpoint value for the first channel and high endpoint value as the last channel when calculating mc channel values.
2 = 'Low Only'
(
Use Low
)
Uses the low endpoint value for the first channel and calculates all other channel values accordingly.
3 = 'High Only'
(
Use High
)
Uses the high endpoint value for the last channel and calculates all other channel values accordingly.
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.
Messages
int
Converted to float
- function index
[int]
float
When mc.evolve~ receive a float (0-1), it outputs a list out its right outlet containing its output range at the given location.
- function index
[float]
list
A list message adds a new breakpoint to the function stored by mc.evolve~. Up to 3 values can be used to specify the x (input) postion, upper y (output) value, and lower y (output) value. If the list contains two values, it creates a breakpoint with a fixed y value at the x postion. An optional 3rd value specifies the lower y value range.
- x-value
[number]
- y1-value
[number]
- y2-value
[number]
chanval
When mc.evolve~ receives a chanval message it will send the value of its output for a given channel index (1 - N) and input value (0-1). This value is a point within the output range at the given input position.
- channel
[int]
- index
[float]
clear
The clear message with no arguments clears all breakpoints in the current function. An optional index argument can be used to specify a breakpoint to clear. Breakpoints indices are ordered based on their x-position, with position 0 representing the 0.0 x position. The mc.evolve~ object always maintains a breakpoint at both the 0. and 1. positions.
- breakpoint_index
[int]
printfunction
Sending the printfunction message to mc.evolve~ prints each breakpoint in the current function on its own line to the console. Breakpoints are multi-element lists in the form x: (float) y: (float1) (float2) .
signal
Use a phasor~ or other time-varying signal with a 0-1 range to drive the multichannel output of mc.evolve~.
