In this scenario, the BROWSE encoder has the same effect as the TEMPO encoder when mak-
ing tempo adjustments. If the Deck is assigned as the 
MASTER, tempo adjustments made with
the 
BROWSE encoder will also be applied to any other Deck with their SYNC button activated.
In scenarios where automatic Deck synchronization isn't possible, e.g. syncing a TRAK-
TOR Deck with an external audio source, you can use this method to manually dial in a
Deck's 
BPM.
2.9 Using Keylock
 
When synchronizing tracks, you end up altering at least one track's tempo, which consequently
changes their pitch (or key). For small tempo adjustments, this mostly isn't going to be an is-
sue;  but  when  the  tempo  is  changed  more  significantly,  the  resulting  pitch  change  might
sound  unsuitable:  kick  sounds  would  lose  their  impact,  vocals  would  sound  unrealistic,  har-
monic  instruments  would  become  dissonant  when  mixed,  etc.  To  avoid  issues  like  these,
TRAKTOR provides the  Keylock feature  which  uncouples the  pitch and the  tempo of  a track.
This allows you to basically lock the pitch while adjusting the tempo or vice versa. In order to
activate Keylock from the S5, do the following:
Prerequisites
We assume here that the S5 is in the following state:
▪ The track Techno 1 is loaded on Deck A and playing.
Adjusting the Tempo and preserving the Original Pitch
If you want to mix a track in its original key to another track with a faster tempo, you need to
lock the key before adjusting the tempo of the track:
