Reply to Will Traktor Scratch Pro work with IMG STAGE LINE - CD 30 DJ?

Hi guys, just a quick question about compatability. I have Traktor Scratch Pro with the Audio 4 dj Soundcard and timecode cds. I know theyre old but Ive seen a good offer for these cdjs but I don't believe they don't work with MP3 cds, just CDRs, does this mean they wouldn't work with Traktor? Thanks!
