Hi,
apologize,

in effects the one which I try to make has only the visual apprence of a 
EQ.
It is a sort of multi-band-filter
Every slider can put a 0 a group of frequencies.
The cildren can cancel groups of frequencies or can listen isolate 
portions of sound spectrum (like with the eraser on a design).

Not knowing as to call this kind of filter I have defined it EQ,

but I hope that you will apologize me, I am not a suond designaer :)
