Open Sound Control libraries for integrating Flash / Actionscript 3 with Max/MSP, SuperCollider and any other OSC capable system (Reaktor, Plogue Bidule etc..)
Because AS3 doesnt support UDP sockets this library also contains a Java OSC client and server which can be used for providing a bridge between UDP and TCP connections. e.g.
Flash (via TCP) -> Java -> Reaktor (via UDP)
The Java client and server are based on the Apache Mina framework and can easily be used seperately for other purposes.
