Let's keep it short and sweet:
>Import WAV files to Ableton
>When played, they are way too fast
>Sample rate is the same in Ableton preferences as it is on the WAV (44.1)
>Seg. BPM of each clip is not the same as the master track, which is at 125
>I can only change the Seg. BPM by doubleing or halving it, neither of which get it to 125
>Lots of Googling has not helped me
Edit: Figured it out. For someone that might read this in the future, you have to make sure "Warp" is selected, and then click on the yellow warp marker in the sample window (might be hard to see). This should allow you to change it.
