21Understanding OSC and Network Cues

One of QLab’s greatest strengths is its support for the Open Sound Control (OSC) protocol, a standard for computers and devices to communicate over a network. OSC can be sent or received by QLab, which means that you can use QLab to control other OSC-compliant software/hardware or control QLab from the software/hardware in question. The following chapter examines the relationship between QLab and OSC and some of the ways in which OSC can be used.
