Reply to Quick question about timecode and TP2/S4

I was wondering, is the software different between Traktor Pro 2 and Traktor Scratch Pro 2?

As in, if someone has an S4, and already had timecode vinyl etc, and also an Audio 8 (Traktor Scratch Pro), do they have to upgrade the Audio 8 Scratch software to Traktor Scratch Pro 2, or does the Traktor Pro 2 software with the S4 do all the same features.

I probably am not explaining it well, but I am trying to figure out for my friend whether he needs to get the timecode upgrade for his S4 to use my Audio 8 and timecode. He believes that no upgrade is necessary as he will be able to use the Traktor Pro 2 that came with his S4 with the Audio 8 and timecode.

I'm just not sure on that, and was wondering if anyone could confirm. My impression was that to use timecode, you needed to upgrade the software to Scratch software, as well as have the timecode and audio card that supports it.
