mc.number~

Multichannel signal monitor and constant generator

Description

Use the mc.number~ object to display or generate multichannel signal values.

Examples

Discussion

The mc.number~ object operates in two different modes. Switch modes by clicking on the icon on the left side of the object box.

In signal monitor mode (denoted by a wave) it displays the value of the multichannel signal connected to its left inlet. Click one of the dots below the number to select an input channel for display.

In signal output mode (denoted by a downward arrow), mc.number~ displays a value received in the left inlet or entered into the object box. This number also becomes a constant signal value for a channel in mc.number~ 's multichannel signal output. Highlight the object for typing by clicking on the number, or scroll on the number to change its value. Click one of the dots below the number display to select a channel for generating a signal.

Arguments

None.

Attributes

bgcolor [4 floats]

Background color

chans [int] (default: 0)

When the value of chans is non-zero the mc.number~ object displays and outputs a fixed number of channels regardless of the number of channels in a connected multichannel signal. When chans is 0 (the default), the object auto-adapts to the channel count of the connected multichannel signal.

color [4 floats]

Sets the color of the active channel indicator.

displaychan [int] (default: 1)

The displaychan attribute sets the currently selected channel for display in either signal monitor mode or signal output mode. In addition, the value of displaychan attribute determines the output channel whose value will be set by numbers sent to the object's left inlet.

ft1 [float] (default: 0.)

The ft1 attribute sets the ramp time of the output signal in milliseconds. The default time is 0.

interval [float] (default: 100.)

Sets the mc.number~ object's display update rate (in milliseconds). This is also the rate at which the connected multichannel signal is sampled and output as float values out the object's middle outlet.

maximum [atom] (default: <none>)

Sets the maximum value that can be displayed or output.

minimum [atom] (default: <none>)

Sets the minimum value that can be displayed or output.

monitormode [int] (default: 1)

The monitormode attribute enables or disables signal monitor mode.

numdecimalplaces [int] (default: 0)

Sets the number of decimal places shown for a displayed or entered value.

sigoutmode [int] (default: 1)

The sigoutmode attribute enables or disables signal output mode.

style [symbol] (default: )7.0.0

Sets the style to be applied to the object. Styles can be set using the Format palette.

textcolor [4 floats]

Sets the color for the mc.number~ object's number values. The textcolor attribute is mapped to the textcolor_inverse style color.

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

bang

The bang message currently has no effect.

int

Arguments

input-value or ramp-time [int]
Converted to float.

float

Arguments

input-value or ramp-time [float]
In left inlet: The value becomes a constant signal for the currently displayed channel in the multichannel output. When mc.number~ is in signal output mode, the value is displayed. If the ramp time is non-zero, the output signal will ramp between its previous value and the newly set value.
In right inlet: Sets a ramp time in milliseconds. The default time is 0.

  (inlet1)

Arguments

ramp time [float]
In right inlet: Sets a ramp time in milliseconds. The default time is 0.

list

Arguments

input-value [number]
ramp-time [int]
The first number sets a constant value for the output signal (see the float message above for details), and the second number sets the ramp time in milliseconds.

allow

Arguments

display-mode-availability [int]
The word allow, followed by a number, sets what display modes can be used. allow 1 restricts mc.number~ to signal output display mode. allow 2 restricts mc.number~ to input monitor display mode. allow 3 (the default) premits the use of both modes, and lets you click on the icon at the left side of the object to switch between them.

flags

Arguments

appearance/behavior [int]
The flags message is provided for legacy support of the mc.number~ object; all the original functionality is now provided by object attributes.

max

Arguments

maximum value [number]
The word max, followed by an optional number, sets the maximum value of mc.number~ for signal output. The word max with no arguments clears any previously set maximum value.

min

Arguments

minimum value [number]
The word min, followed by an optional number, sets the minimum value of number~ for signal output. The word min with no arguments clears any previously set minimum value.

mode

Arguments

display-mode [int]
The word mode, followed by a number, sets the current display mode, if it is currently allowed (see the allow message). mode 1 sets signal output mode. mode 2 sets signal input monitor mode.

(mouse)

Click on the icon at the left side of number~ to switch between signal monitor mode (wave) and signal output mode (arrow). When in signal output mode, click on the number to highlight it for typing. Scroll on the number to change it. In either mode, click the dots below the number to choose a channel value to display.

set

Arguments

set input [float]
The word set followed by a number sets the mc.number~ object to display that number in signal output mode without causing output.

signal

mc.number~ samples values from a connected multichannel signal at a rate specified by its interval attribute. Sampled values are sent out the middle outlet, preceded by a channel index out the right outlet. When mc.number~ is in signal monitor mode , it displays sampled values for the currently selected display channel.

Output

float

Out middle outlet: Samples of the input multichannel signal are sent out at a rate specified by the interval attribute.

float

Out right outlet: Immediately preceding sample output from the middle outlet, mc.number~ outputs the channel index of the sampled signal value.

signal

Out left outlet: When audio is on, mc.number~ outputs a multichannel signal consisting of constant values, set by values in signal output mode or received in its left inlet. If a non-zero ramp time is set, changes in output will ramp from previous to new values over the specified time.
