"So, if you want to record audio from your synth into mp3, you really need a harddisk-recording-card to record the SOUND from the synth."

Hi stigF!
sorry for disturbing the conversation but...
I think we can put the Xp playing and recording it directly into a WAV file on the PC. A track each time and then mix or edit all the wav tracks. Then convert the arrangement into AUDIO and mp3. Can I do that?

"General MIDI (GM) is possible of course, but very very weak compared to what the XP can do. It has to use one of only pre-defined 128 sounds...."

That is my problem, also.
