Yes I do use the demo. The bit crusher was a .vst that I found somewhere online. I can't remember exactly what it was since I moved and deleted it from my friend's computer. I suggest just searching for 8-Bit vst, and finding one that you like. All you do is download the VST, put it into your VST folder that is in your FL Studio folder, which will be where ever you put it. When you do that, right click on a plug in, click "More Plugins" and do a quick scan. When it picks up the file, check it, and right click the plug in again. It should be somewhere. It's all in alphabetical order, so remember your abc's.
