Hi, I've just registered as I got an MZ-N910 v cheap off German eBay and have just recorded an opera performance live - even in the cheapest seats with just a clip-on mic I'm amazed at the quality. I hope to make decent single instrument recordings away from my PC for eg uploading to YouTube, as well as taping further concerts! I did my research quite well before selecting the model but not quite well enough. I assumed that the USB interface would enable 2-way operations but having done some more research on the Web I'm now not so sure. I appreciate that questions like this get posted every couple of weeks by new users like myself and can be a pain, but can anyone fill me in on the current state of affairs - is it now possible to download tracks to PC as files using the USB interface, or must they still be recorded on the PC via the LineIn? If the latter I'd also be grateful for recommendations for a decent sound card as I'm using the motherboard's inbuilt one - some people have recommended the Juli@ one or is this overkill for just a simple LineIn requirement? - ie would just need decent quality, not fancy connections etc.
