Very cool.  How would the FPGA be used?  I would think a dsPIC could do wavetable
synthesis by itself, so I imagine that you have something special in mind for the FPGA
to do?.

Also, that's the same DAC as on the little boards you designed.  If you use 192 as a
divider and 38.4 MHz as MCLK, you get 200 KHz as a DAC sample rate.  I've tested that
on the little Avnet board because you can actually get 38.4 MHz with it's xtal and a DCM.
