+# orx-osc
+
+Open Sound Control makes it possible to send and receive messages
+from other OSC enabled programs in the same or a different computer.
+Used to create multi-application or multi-device software.
+
+Can be used to remote control your program from a mobile device,
+to produce sound in a audio programming environment, make games
+and networked experiments.
+
+Orx-osc is a wrapper around javaOSC
+
+## Usage
+
+```kotlin
+// PORT IN and OUT: 57110
+val osc = OSC()
+
+osc.listen("/live/track2") {
+    // do something
+}
+
+osc.send("/maxmsp/filter", 500, "hz")
+```
