Ah, I assumed that the USB connector, on say the N710, would be for drag/dropping sound files. Okay I am looking at the NH700 - is is just that one model, or are there others that will fit the bill? Also does the software allow me to drag and drop files both ways - is it as easy as that? Will I be able to record to separate files using just the MD unit, rather than having to go to a PC and use the software? Thanks for all your help. A quick glance at the equipment browser for Sony shows these models seem to fit my bill so long as I can reach them with my meagre budget: Sony MZ-RH10 Sony MZ-RH910 Sony MZ-M10 Sony MZ-M100 Sony MZ-NH1 Sony MZ-NH900 Sony MZ-NHF800 Sony MZ-NH700 Am I right?
