SuperCollider CLASSES


network bundle object
Inherits from: Object
Subclasses: MixedBundle


A bundle object that allows to add preparation messages for async processes. If this feature is not needed, a list object can be used instead.

Class Methods

Inherited class methods

Instance Methods

-add (msg)

Add an osc message to the bundle.

-addAll (mgs)

Add an array of osc messages to the bundle.

-addPrepare (msg)

Add a preparation osc message, which is sent before the bundle is sent.

-send (server, time, timeOfRequest)

Send the bundle to a server. If preparation messages are given, they are sent, the process waits for their reception abd then sends the bundle.

-schedSend (server, clock, quant)

Like send, but the sending is synced to a given clock to the next beat.



A Server.


A TempoClock.


Can be a pair of values: [quant, offset].

Inherited instance methods

Undocumented instance methods

-addCancel (msg)


-doPrepare (server, onComplete)



-sendAtTime (server, atTime, timeOfRequest)


// create a new, empty instance
a =;

// a synthdef that needs to be sent to the server, an operation that is asynchronous,
// i.e. we have to wait until it is finished.
x = SynthDef("test", {, * 10, Rand(9000, 1000), 0.1)) });
// this is why addPrepare is used.
a.addPrepare(["/d_recv", x.asBytes]);
// add is used with synchronous operations, like starting synths.
a.add(["/s_new", "test", -1]);

// the bundle has now the synchronous separated from the asynchronous bundles:

// this can be simply sent - the bundle takes care of the server client communication
// like waiting for the synthdef to be loaded. the synth is started when the preparation
// is finished.

s.boot; // boot the server

s.freeAll; // free all nodes on the server

// scheduled sending: the synths are started on the next beat.

a.schedSend(s, TempoClock.default, 1);
a.schedSend(s, TempoClock.default, 1);
a.schedSend(s, TempoClock.default, 1);

s.freeAll; // free all nodes on the server

// the bundle can contain several preparation messages and messages at a time.
// the proparationMessages are sent first and only when they are all completed,
// the other bundles are sent.
// the bundle can also be reused, if there is no specific allocated buffers/node ids.
