""""""""""but insted of draw it by hands I used FX Graph by Max Smirnov """""""""""

I attempted that one first, but it is math formula oriented,, I would need to have the UI inputs be more like "more amplitude" and such, with a slider or human readable numbers.... lol

fx graph would be quicker than hand drawing. Maybe Brian or someone can combine fxgraph and flow for a 1 shot command that you wanted.....
