Open Sound Control (OSC) is a modern network based communication protocol that can be used to send a variety of control messages between OSC enabled devices. OSC input is supported on every console in the Hog 4 family including Hog 4 PC. When configured properly OSC will enable you to use OSC enabled controllers such as a synthesizers, electronic music instruments, production audio software, and mobile phone apps such as Touch OSC to control the basic functions of the Hog 4 OS.
