Thanks Vintage, you are really helping me unravel things! All songs are about the same % slower, although sometimes one deck starts off ok! The BPM displayed is less than what it should be. First couple of tracks can be manually adjusted, then the tunes slow so much as to be unplayable. All software is up to date, latest version of Traktor DJ, although I haven’t upgraded to iOS7 yet, as I’m not certain Traktor DJ has resolved the issues it had.
