Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

So I've just started playing again after a long absence. As I was going through my characters to jog my memory on how I had them set up, I noticed that under Julia's journal notes I'd written several entries like this: !midi #######

Now, I know that they're referencing midi sequences I created for her "song book."

However I can't for the life of me remember whether that was actually an in-game function, or how to even use it. Is that something still in the game or has it been removed? And if it IS still there, can someone point me to how it even works?

Looks like its probably in here: viewtopic.php?p=687095#p687095

Page 2-ish?

That's sounding familiar. And oh look, I posted in that thread, lol.

Edit: Although HM, that thread doesn't seem to say much about how to actually ACCESS AoS Tools... I just searched my PC and I'm not seeing an EXE or installer, or even a download for it from when I was here before.
