Ableton bad quality playback
You can also quantize all of the warp markers, by right clicking in the clip audio window and going to "Quantize Settings". That should align it all together. I doubt that "Center" was originally bounced at 102.12, so I would definitely change the initial warp marker to match the original BPM... maybe 102?
@jakes ableton uses a different algorithm with will make the warping less noticeable on instruments such as pads and synths. Use beats for drum grooves and beats. Use complex if there is a pad or synth that you are warping.
