Wonder if anyone can give a brief explanation of the Aural Exciter 
Variation Effect (#9)

It seems to me that it segments the frequencies above the cutoff 
frequency, runs them through an overdrive and then reconstitutes the 
signal. (or something like that)

Is this correct, or does it also do some animation (like a chorus)?

Is this effect unique to Yamaha? Is it similar to the sonic maximizer 
(BBE)?

Sorry for so many questions. I'll take whatever you know.

Thanks in advance,

Jerry
