Just put up a video sharing my technique on how to warp a song in about 2 minutes. Please note that in the video I mention using Serato (since its free to download) but if you already have Traktor that will work the exact same.
good tutorial on how to warp, if you have a nice processor you can do this is 30 seconds per track once you have some practice.
I’ve warped a couple hundred tracks and this is the method I use, if it doesn’t warp properly I go a little more into detail on adding tabs on the drop and every 32nd of 64th, depending on what its looking like.
I think that this method would be perfect for you! I was a DJ long before I ever opened Ableton, so you could say this is coming from a DJ perspective.
