down load is no problem. You may want to consider playing the Midi while the PC recorder is running. Edit that for length. Then burn an audio CD using the WAV. MAke all the all the Audio controls visible and see what controls what (look for recorder controls too)

BUT

Set the recording parameters well. 16 bits essential, sampling at 44K is best. The burner may cope with grot recordings but they sound terrible. READ the HELP files on each application - they give you clues like this. I use Soundforge XP - to edit and record. MP3 converters may insist on 44K stereo 16 bit files.
