I just picked up an MZ-NH700 after years on my clunker of an R37, EXPRESSLY in the belief that I could finally 'flash' my sound recordings to the PC for editing, rather than having to run through my line-in in real time. I use the MD exclusively for mic-recorded interviews and live music recordings.
Now I find out that the seemingly hyper-paranoid boys at Sony won't let me do this. Sure, I can upload my field recordings, but only into SonicStage (and only once!), and the result is a format that I'm not allowed to edit.
I have to say that this really pisses me off. Sony has hyped this great new uploading function, but crippled the whole thing by barb-wiring my audio behind inaccessible USB transfer protocols and the untouchable OpenMG file format. Furthermore, my calls for clarification to the Sony help desk were met by drools and shrugs.
If, after all this, I still have to play my audio through my PC line-in, I intend to pack up the NH700 and get my $400 back. If I'm wrong on any of these points, please let me know.
