Depending on the DSP, you'll probably find you *need* 24bit DAC/ADC to get
it working.
I doubt it would work correctly with a 10bit one, as I imagine the data
stream comming from the DSP is probably fixed.

Sounds like an ideal app for a Chameleon :-)

probably 16bit then.

hehe, a complete FM synth really.
