OCTOBER 2011: I'm not sure what this is good for yet, but it is really cool. You can play your musical sequence from the sequence editor on one machine, and have it show up on another computer running the S3 Visualizer. For this demo I'm running Light-O-Rama's S3 3.0.2 software. On my laptop I'm running the "Light-O-Rama" Sequence Editor. From the menu-bar I select "Edit" then click on "Preferences" then pick "Visualizer Preferences". Then I set "Visualizer Host" to the IP address of the computer running the "Light-O-Rama Visualizer". On the machine running the Visualizer I setup by opening the "Light-O-Rama Visualizer", then I select "File" from the menu-bar then click on "Options". I select tab 6 "Com/Ref", then find the "Communications" pull down and change it from "Local" to the network adpater on that computer. I close out by clicking on "Ok". Then on both computers I exit out of the Sequence Editor and Visualizer and start them both up again. Then I load up a sequence in the Sequence Editor on the first computer and start it up. The visualizer then displays the light show on the other computer (but not sound). Impressive. You can also change the UDP port used if you want to. Since the transfer uses UDP there is no error correction and dropped packets are not transmitted so if the connection is slow or congested you will have problems. Also I found the process to be a little fragile and had to stop and start the applications on the two machines a couple of times to get it to work.
