→OSC Messaging
=OSC Messaging=
The bullroarer nodes use Open Sound Control to communicate with the host computer. You can find an introduction to Open Sound Control [http://opensoundcontrol.org/introduction-osc here], and details of the [http://opensoundcontrol.org/spec-1_0 OSC Specification]. The OSC messages Messages from each node are addressed differently to each tagged with the ID of that node. They start with a base address pattern of ''/br/'' followed by the node's number, 1-21. For the examples below I am using messages from node 1, so they start with the base address for node 1, of ''/br/1/''.
Control messages from the host computer are sent directly to each node at their IP addresses. Thus, they do not contain any node-specific information in their addressing pattern.
