Hello, i remember that long ago, i think on ofice 97 or maybe office xp, powerpoint has a feature that can start background music i think that midi, and stop seamless... but then these feature was removed in powerpoint.

Anyone know what is the name of these feature and also please confirm the last powerpoint version that has it. I want to use an emulator to run the software again, to make some blog of office history and some videos showing the feature.
