another discovery... you can use it like an exciter but without the need for crossovers. Simply EQ out the frequencies you don't want to enhance in ReaEQ and then copy the instance of ReaEQ and on the 2nd instance use the 'flip all bands' command
I assume this is because of pink noise equal energy in all frequencies thing, who cares why really
Edit: That still works, but I found something even weirder. If you run the pink noise through the distortion again, it doesn't turn back into white noise, it stays the same, or might get even 'pinker'! I'm trying it now on music, distorting and filtering it and then running a bunch of times to see what happens
