this is what i do.
i got an md8 track recorder and i use the monitor outputs. I use an adapter cable that is rca on one end and phono on the other. by phono,, i mean the same plug that fits your sound card or a walkman. Im sure there is a much better way,,,but i just figure it out as i go. Anyway,, i plug it right into the mic input. If you try this,,,, make sure you turn the monitor output on the track recorder down to zero to start,, so you dont overload your sound card. then use a program to record. i use cool edit . It lets me take a prerecorded song or track and "boost the sound" or add echo or whatever i want. I found that when i first did tryed this,,, i needed to disable my "mic boost". Its a setting in your advanced volume control. Hope some of this has been helpful.
