Bill--

Here is C# code that ... doesn't work. 

https://gist.github.com/robertmeta/42358108f589ebd740ca0c8669cb381e

That is the code and instructions to get it running, if you can 
make it change pitch, please do. I tried a bunch of approaches 
when I was working on this, but if it is possible, hopefully 
someone from this list can show me, because every attempt I made
failed. 

To do it I was working on hand implementing pitch manipulations 
in C# using NAudio, so I would much rather have a line of XML I 
can add.  :)
