Well...finally got started. The gear I'm using is:
Master MD->MDS-JE770->optical out->Midiman CO2 (yeah, found one cheap)->digi coax out->M-Audio 24/96 soundcard->Adobe Audition 2
I was a right laugh trying to get the settings right. I haven't had this much pc "fun" for eight years, or more. Took about an hour to work out that the input and output bit rates had to be the same in windows as well as audition. Then the "release ASIO driver" box was ticked, which meant that clicking an another app stopped the recording. I can see why using a MZ-RH1 would be a good idea. I just don't have the funds for one at the moment.
Disappointingly, a lot of the recordings are LP2, but since most of them are the only source, this doesn't really bother me too much.
