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.
I am planning on rewriting the hum system I had, it was supposed to be in U50 but that failed...
This would allow you to select the hum you want for the desired tardis you're in.
And which also will be streamed to any place in the tardis dimension just for you.
Thanks, I look forward to it
