    A lot more general purpose that what I had in mind.  It also could make
a nice machine, I would imagine for doing a virtual analog......hmmm there
is another thought.

    Except for the big block of RAM and the Wave Table, I think everything
thing you have there would fit real nice into an FPGA, in fact, you might be
able get two in a single FPGA.

    By the way, and it could be my connection (we seem to be having a bit of
trouble today), I was only able to get about 1/2 of the above jpg.  I got
the jist I think.  I will try again latter tonight.
