Query: Serious problems uploading recordings done with external mic

The minidisc can be used for several things. Among those:1) listening to songs recorded in CDs. I have to say I am very happy with this fonctionality.2) Recording songs with an audio microphone (not included).Very interesting fonctionality for people who play music and want to record themselves in rehearsing or live concerts (in my case, playing the violin). This is what I bought it for. The quality of the recording is excellent, given the means and compared to previous non-professional portable analog formats. Serious problem: the software included does not permit to upload songs to the computer not downloaded before so you can not transfer it easily to other audio formats. I asked Sony customer service and basically after three tries of their complex web support system I got either no response or authomatically generated useless responses.
