Help recording an audio track?

Question

I have Sonar 3 Producer Edition (Yes I know, it's a little bit out dated). I'm doing a cover from another band, so I have the song running in the back as I'm recording on the audio track. My problem is; The audio track picks up the song in the back as I'm recording, I found that out after I got done recording the audio track. I just want what's coming from the input only, not the song in the back.

I don't want to mute the song all together, otherwise I will have trouble playing it because I don't know what comes in where by heart. So I just want what is coming from my input, nothing else.

I have a Creative SB X-Fi sound card, so I don't if that will help.

It's getting annoying really.... So any help will do.

Answer 1

First you gotta just nip it in the bud. Then you gotta say "wtf mate". Call the service center and ask for Bruce Wayne. Then be like "Well hey buddy, I need to um record a track for a cover. Because it's cool. So help. Bye"

Everything should work fine after that.
