Open Sound Control (OSC) is a protocol for communication among computers, sound synthesizers, and other multimedia devices that is optimized for modern networking technology. OSC's advantages include interoperability, accuracy, flexibility, and enhanced organization and documentation.

Features:

• Open-ended, dynamic, URL-style symbolic naming scheme
• Symbolic and high-resolution numeric argument data
• Pattern matching language to specify multiple recipients of a single message
• High resolution time tags
• “Bundles” of messages whose effects must occur simultaneously
• Query system to dynamically find out the capabilities of an OSC server and get documentation
