transport
Description
Starts and stops the passage of time for objects linked to a transport. If given a name, the transport object will control a time context of the given name, otherwise it will control Max's global 'internal' transport. The transport object reports time consistent with the time formats used in Max.
Examples
Discussion
Note for Max For Live Users: Currently translating a beat time song position in Max for Live will only take the global tempo into account and might not be accurate when the Live set contains tempo changes.
Arguments
None.
Attributes
clocksource [symbol]
The current timing source for the transport. The default source is Max's internal clock but other timing sources may also be used.
name [symbol]
There can be multiple named transports running simultaneously. By default, a transport will be associated with Max's global transport. If a name is provided then a new transport is created with that name and can be referenced using this attribute.
resetbarcount [int]
Toggles whether the bar/beat/unit counter advances to the beginning of the next measure when a time signature change is received. By default, this is disabled (0).
tempo [float]
Sets the tempo in beats-per-minute for this transport.
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. 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'

'64'
'72'
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.
jspainterfile [symbol]
JS Painter File
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.
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.

float
Out 3rd outlet: When transport receives a bang, the units are sent out the third outlet.
Out 4th outlet: When transport receives a bang, the current resolution (ticks per beat) is sent out the fourth outlet.
Out 5th outlet: When transport receives a bang, the current tempo is sent out the fifth outlet.
Out 8th outlet: When transport receives a bang, the number if raw ticks is sent out the eighth outlet.
int
Out 1st outlet: When transport receives a bang, the current bar is sent out the first outlet.
Out 2nd outlet: When transport receives a bang, the current beat (within the bar) is sent out the second outlet.
Out 7th outlet: When transport receives a bang, the Transport State is sent out the seventh outlet. A value of 1 means that the transport is on, and a value of 0 means that the transport it off.
