+
+Open Sound Control
+------------------
+
+This example shows an implementation of OSC (Open Sound Control) which was 
+developed at UC Berkeley Center for New Music and Audio Technology (CNMAT).
+
+It is designed to be run alongside resources/osc/osc.js
+
+The OSC server port on which to receive is set in `setup()` 
+via `oscServer.setup()`. Likewise the OSC client port on which to 
+send is set in `oscClient.setup()`.
+
+In `setup()` an OSC message to address `/osc-setup`, it then waits 
+1 second for a reply on `/osc-setup-reply`.
+
+in `render()` the code receives OSC messages, parses them, and sends 
+back an acknowledgment.
