It's a part of the MM skin engine. I doubt there is any way to access it outside of MM skinning.

Does anyone have any ideas? which object it is?

I have been searching through the objects list and can't seem to find the visualizer object...

Howdy, I want to snag the little mini DSP object that displays the music levels as the song plays, I want to build it into an external window, but I can't figure out what object is running it. If you don't know what I am talking about check out the bottom right corner of the Glided skin.
