More dip in bass

[Matt Wynne]

One of the local techs here in long island, during a presentation detailing 
his key height/key dip setting procedure, said he likes to set the dip on 
the piano in something of a bell a curve, being slightly deeper at the ends 
and slightly shallower in the middle.  This, he said, was to compensate for 
the gradual felt compression which will occur during playing, since the 
middle gets more wear than the ends.

Just another idea for the mix.
