Abstract:
A control surface has a network connection for connecting to a host computer and has an address and an input for communicating data with the host computer. The network interface processes packets received from the host computer. Packets received include a first type and a second type, and the type is indicated by data in the packet. Upon receipt of a packet of the first type an acknowledgment packet is sent. Upon receipt of a packet of the second type, an acknowledgment packet is not sent. The packets of the second type include at least status information for a plurality of meters in the audio control surface. The status of the meters on the audio control surface is overwritten with the status information provided in any packets of the second type.
