transport

Control a master clock

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 master 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 such as ReWire 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.

Sets the tempo in beats-per-minute for this transport.

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.
