I recorded a song I played as a techics format. Then I wanted to save it as an SMF format, but read that I had to do a conversion of the APC or it would not convert to midi. So, I loaded the song into the sequencer, then I went in to do the APC conversion and saved it to disk. When I went back to play the disk, I didn't have any melody. I only had the background. What am I doing wrong? I read the manual, and it's over my head since it doesn't take me through it step by step. Please help me.
