Traktor Scratch: Combined Analogue/Digital Setup
Are you using Traktor with timecode media (it doesn't matter whether you use timecode vinyl or timecode CD) and do you also use "analogue media" such as normal vinyl or audio CDs at your gigs?
Then this little tutorial will show you how to configure your Traktor Scratch setup in a way that you can use both media without switching between THRU mode and deck mode during your gigs. Instead you can simply use another channel fader on your mixer.
Cabling
You need a 4 channel mixer and a Traktor Audio 10 to accomplish this setup. The cabling for the configuration looks as follows (of course, you could use CD players instead of turntables if you wish):

- The turntables (or CD players) are connected to inputs C and D
of Traktor Audio 10.
- For inputs C and D direct thru is activated (you can do this
with the control panel of Traktor Audio 10 and save this setup as the default
configuration, or you can use the context menu of the deck letters).
- Outputs C and D are connected to Inputs 2 and 3 (the two middle
faders) of the mixer. Outputs C and D supply the THRU signal. Use these two
faders if you are playing normal vinyl or audio CDs.
- Outputs A and B are connected to Inputs 1 and 4 (the two outer
faders) of the mixers. Outputs A and B supply the audio from Traktor deck A and
B. Use these two faders while using timecode media on the corresponding
turntable/CD player.
Configuration in Traktor
In the Traktor GUI this configuration looks like this:

Deck A and B are set to Scratch Control, and for deck C and D the THRU mode is activated.
Open the Preferences/Input Routing dialog and configure the deck/channel assignment as shown in the following figure. Make sure that the channels on the audio interface that you have connected the turntable/CD player to, are assigned to deck A and B. With this routing the incoming timecode signal controls Traktor decks A and B

Open the Preferences/Output Routing and configure the routing as shown in the following figure:

Check out this configuration and have fun.
