Thanks Mac. I think that your earlier idea of a new mic preamp that has digital output is my best option, although not as cheap as I wished. I've made a quick scan of the internet and the ART DPSII Digital Preamplifier System seems to fit the bill. I envisage hooking the analog output from the SD2 to the emu's two mic inputs, and using the ART preamp for my mic inputting it digitally into the emu's SPDIF input. I think this will be a satisfactory, if someone expensive, solution giving me keyboard, mic, and SD2 inputs into BIAB and Sonar as intended. As always, thanks for your advice. It is appreciated.
