The central hub of Quintet.net is the Server, to which all participants first log in. It keeps track of the IP numbers as well as the name and location of each user (Client, Conductor or Listener). The musicians can then play their lines into the Clients and send them onto their journeys in cyberspace. Having arrived at the Server, the data packets are copied and sent to all Clients (including the originating computer) and Listeners.

In addition to managing the data streams, the Server also assumes further musical tasks, such as manipulating the incoming stream of music with effects algorithms. These include filters, harmonizers and transformation effects that can alter the character of the music dramatically and allow the players to also perform duets with themselves. Streams from various components can also be mapped to control the parameters of the other components.

Once a user has successfully logged into the Server, a small Max patch resposible for sending control data to the IP addresses provided by the Clients will pop up.

After clicking onto an entry inside the three fields the Server will ping this address and measure the minimum, avarage and maximum delays a packet is expected to have. The clients can adjust their event buffers accordingly.
