i’m not sure with traktor, as i’m using serato right now (but looking to move to traktor).
i switch between dubstep, glitch hop, dnb, house, 2 step, hiphop, alternative rock, and a few other genres within a mix so here’s a few tips on what i do with my setup (vci-300 + serato itch) that may be able to be applied to traktor:
-half time all of your tracks. if you have a track at 140, your software should say 70. this keeps all of your bpm ranges much tighter for tempo change (moving between 65 to 70 is a lot easier than from 65 to 140).
-ramping. oldest trick in the book. if you need to go from 60 to 70. ramp the 60 to 65, play a track at 65. ramp the 65 to 70. play the next track at 70. remember keylock is your friend.
-using tracks that have tempo changes built in. i have a collection of tracks that i use specifically to switch tempos because the producers built a tempo change into the track. something that goes from 70 to 90 for instance is a good means to bridge dubstep into hiphop. something that goes from 174 down to 140 is a good way to bridge dnb into dubstep, etc. even if the tracks arent phenomenal, you can always cut them up to only use them for the tempo change and then drop into your new track.
-dont be afraid to go crazy with the pitch slider. as long as keylock is enabled you have a pretty solid range of tempo change ability before too much distortion kicks in. you can often use this as a trick (bassnectar does it all the time). just slam that pitch slider down 30bpm over the course of 4 bars and punch the next track in on the 1. combine it with a grain effect for even better results.
-i think the freeze trick is a delay/echo combination trick, iirc. i use my korg kp3 to do this, i think… i’ll have a track set at 90bpm and i’ll run a delay+echo on the last 2-4 bars at a different tempo (let’s say 70) and cut the fader over to the deck that i have the 70bpm track loaded into. the 90bpm track will delay/echo at 70bpm for 4 beats then i drop the 70bpm track in.
i’m just now starting to learn traktor but i’ll def be on the lookout for figuring out tempo change tricks and i’ll likely come back to share some more once ive figured out the workings of the software.
remember keylock is your best friend!
