CUE MIX Knob
Pre-view a  new  track in  your 
CUE and  raise  the channel's  GAIN  until  the mix  of  both tracks
sounds good when the 
CUE MIX is in center position. That way, when you actually mix it in to
the 
MAIN, you can be certain that it blends well.
4.4.2.4 TEMPO Encoder
 
The central 
TEMPO knob controls TRAKTOR's Tempo Master in BPM. All synced Decks automati-
cally follow tempo changes.
TEMPO Encoder
The TEMPO encoder changes tempo in increments of .01 BPM. Hold SHIFT to change
in increments of 1 BPM.
A shortcut provides tempo control functionality via the Deck's display.
You can only set an individual tempo for un-synced Decks. If you adjust a synced Deck's
tempo, the Tempo Master's BPM change along with it.
So for behavior similar to using a dedicated Tempo slider, make sure the Deck isn't synced.
1. Press Display Button 1 to open the 
BPM pop-up.
