udpreceive Reference

Receive messages over a network

udpreceive

Description

Receives messages transmitted over a network using the User Datagram Protocol (UDP).

Examples

Look ma! No hands!!!

Arguments

port [int]

Specifies the local port that the udpreceive object will use to listen for incoming messages.

full-packet [symbol]

Optional

The udpreceive object and its counterpart the udpsend object provide support for third-party Max objects that work with the Open Sound Control (OSC) protocol developed by the Center for New Music and Audio Technologies (CNMAT) at the University of California, Berkeley. An optional symbol argument (it can be any symbol) specifies that the udpreceive object should pass on UDP buffers as OSC 'FullPacket' messages instead of decoding them and outputting them as Max messages.

Attributes

defer [int] (default: 0)

When enabled, messages are sent out on the low-priority queue instead of the scheduler thread. Especially in Max for Live, this can reduce the chances of audio glitches and dropouts.

quiet [int]

When enabled, status notifications to the Max Console are suppressed.

Common Box Attributes

annotation [symbol]

background [int] (default: 0)

color [4 floats]

Sets the color for the object box outline.

fontface [int]

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.

patching_rect [4 floats] (default: 0. 0. 100. 0.)

Sets the position and size of the object in the patcher window.

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]

Messages

maxqueuesize

Arguments

maximum [int]
The word maxqueuesize, followed by an integer, sets the maximum number of incoming messages that can be in the queue at any given time (default=512). The work queue will grow as needed until this maximum limit is reached. In high-traffic or high-speed situations, you may need to increase the maximum queue size to avoid dropped messages.

port

Arguments

port [int]
The word port, followed by a number, sets the local port that the udpreceive object will use to listen for incoming messages.

Output

anything

All OSC-compatible UDP messages received at the port number of the host computer (designated by argument or the port message) are sent out the outlet.
