Ok, After further testing today... the LP / Mono is working, BUT I still get NOISE depending on the Freq / Hertz...

The spectrum this time only show a black boundary not in the MIDDLE, but TOP area only... what ever the Freq limit is set to... i.e upto 11000
as in there is No Falloff...
As far as I can calculate, there needs to be a loop which decreases the SET Freq depending on TIME...to get a side slope just like in the GREEN Mid graph i posted earlier..

Does that seem to make any sense?
