Fairlight-CMI

I've got a HxC and a 50 to 34 pin cable adaptor made, and some Fairlight .IMD disk images. Could someone lay out the steps needed to get the IMD files into a form that the HxC can use for the Fairlight? 

I assume it's like with use on the Emulator II where there is a disk overlay file that must be mated up with the data from the IMD so the HxC can feed it to the Fairlight.

Thanks!
