That is really interesting Rob, thanks for the demo.  Can you tell me  
though, with the A-B sound track, I am assuming this is the  
unfiltered sound then the apEq filtered track, and keeps switching  
back and forth between the two.  I wasn't sure if an Equium version  
was also included.

I have never tried this sculptured method of applying many small  
incremental filters to 'sculpt' around the shape of the sounds, but I  
certainly do plan to try it now!

thanks again,

Vicki Powys
