So I just started using my DJC4 controller and Traktor Pro software. So the question I have is regarding beat matching and transitioning from one BPM to the next (whether you are going up or down). For example if I start my set with a song at 130 bpm on Deck A and then I want to pick it up and my next rack on Deck B is at 134 bpm I noticed that if I hit the "Sync" button on the controller it will make the bpm of the 2nd to 130. So after I load another track into Deck A again and when I hit sync (even if the bpm on that track is 134) it will go down to 130 bpm again. So song after song I would be stuck at that same bpm. I guess my question is how do you start to transition from low bpm songs to higher bpm songs when you keep using the sync button and it drops the bpm to the lower bpm? What is the best technique or method to do transitions here to make it smooth and pick up the bpm from song to song? I was using a software called MixMeister Fusion which you can drop in tracks after each other (at various bpms) and it would automatically keep them in sync when going from like 134 bpm to 138 bpm. They way it worked was it would start to increase the bpm at the tracking that was ending to start matching the new track, but it did it in a way that kept the mix in sync and you did not realize it. I'd like to achieve the same thing now with my controller and Traktor Pro software. If anyone can give me some pointers that would be great.
