grab
Description
grab can send a message and extract the result from the receiving object.
Note: The grab object cannot be used to communicate from a send to a receive between Max for Live devices.
Examples
Arguments
number-of-outlets [int]
The first argument sets the number of outlets, in addition to the right outlet. If there is no argument, grab has 1 additional outlet.
receive-name [symbol]
If a symbol is present as a second argument, the message received in the inlet is sent to all receive objects named by the symbol, instead of being sent out the right outlet. In this case the rightmost outlet, which would normally send out the incoming message if no second argument were present, will not exist.

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.

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]

Output
anything
Out right outlet: The right outlet should be connected only to the leftmost inlet of other objects. The message received in the inlet is sent out to the left inlet of all objects connected to the right outlet. Whatever goes out their outlets, however, is then intercepted by grab.
Out other outlets: Whatever would normally be sent out the outlets of the objects connected to the right outlet, is sent out the grab object's outlets instead, in response to a message from grab. Whatever would be sent out the leftmost outlet of the other objects is sent out the leftmost outlet of grab, and so on. Note: Only the output that is sent out the outlets of other objects can be intercepted by grab. Other types of output, such as transmission of MIDI messages or printing in the Max Console, cannot be intercepted by grab. Also, grab does not intercept the output of timing objects such as seq, metro, and clocker.
Connecting the right outlet of grab to the inlet of a patcher object, however, will not grab the output of the subpatch. It will simply grab the output of the inlet object inside the subpatch, which is exactly the same as its input. However, grab can communicate with remote objects via a receive object named as the second argument to grab.
If a second argument is present, the message received in the inlet is sent directly to receive objects named by the argument instead of being sent out the right outlet. Any such receive objects should be connected only to the leftmost inlet of other objects. The rightmost outlet, which would otherwise be used to grab the output of other objects, does not appear if the second argument is used.
Note that if grab is connected to other objects remotely via numerous receive objects of the same name, the order in which grab communicates with those other objects is undefined, so the order in which their output will be sent out of the grab object's other outlets is unpredictable.
