Output a bang message at regular intervals
The object's output can be quantized using tempo-relative syntax, and if the autostarttime attribute is set, the object can also start at a tempo-relative point.
The optional first argument sets an initial value for the time interval at which metro sends its output. This time interval can be either a number which specifies time in milliseconds (e.g. metro 100) or notevalue (e.g. metro 4n).
Note: While the metro object lets you specify time in any of Max's standard time formats, the attribute argument should be used when specifying time in any other time unit besides milliseconds or notevalues (e.g. ).
If there is no argument, the initial time interval is 5 milliseconds.
Turns the metro on and off.
If turned on (non-zero) the metro will begin running automatically at the time specified with the autostarttime attribute.
autostarttime [10 atoms]
If the autostart attribute is enabled (non-zero) the metro will begin running automatically at the time specified with the this attribute. The autostart operates as a timepoint object that is internal to metro.
Turn this on to send output in the low-priority queue.
interval [10 atoms]
quantize [10 atoms]
Send output only on the specified time-boundary if appropriate. This is achieved by making internal adjustments to the times used for sending output. The quantization can be specified in the following time formats: bars.beats.units, ticks or note values.
If the applicable time is a 'fixed' unit (for example: ms, seconds, hz, samples, etc.) then this attribute will have no effect.
This attribute names a master time transport. If the time is specified using a 'relative' unit (for example: ticks, bars.beats.units, or notevalues), then the named transport is used to determine delay times based on tempo, time-signature, and other related information.
Common Box Attributes
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.adds the object to the background layer, 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.
Sets the type style used by the object. The options are:
0 = 'regular'
1 = 'bold'
2 = 'italic'
3 = 'bold italic'
Sets the object's font.
Sets the object's font size (in points).
hidden [int] (default: 0)
Toggles whether an object is hidden when the patcher is locked.
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]
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]
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]
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.
Sets the color for the object's text in RGBA format.
0 = 'left'
1 = 'center'
2 = 'right'
In right inlet: The number is the time interval, in milliseconds, at which metro sends out a . A new number in the right inlet does not take effect until the next output is sent.
