I saw this forum and had an idea. I once found out (using the minecraft playsound command) that The Dalek Mod had ambient Tardis sounds. Is there a way to add an interface that allows one to select the ambient Tardis hum that you want so that it plays on a loop in the interior? I managed this with command blocks but they are disabled on DMU Private, so a GUI built in to the monitor may be useful.

 Thanks, I look forward to it
