At the moment I have edit the warps marks of a track, by setting a new start-point (set 1.1.1 here) and used the function “wrap form here straight”. But I like to reanalyzes the track so that Ableton sets the warp-marks for me so I can edit where it is necessary.
I tried to reanalyzes the tracks by clicking the root folder and “Wrap From Here (Start at … BPM)” but that doesn’t seems to work. And there isn’t a *.asd file present in the root folder.
Why would you need to reanalyze the track? If you’re doing a normal house loop or something that is “four to the floor”, a warp from here straight should be more than adequate, and if not just double click a transient marker to set a warp marker and make your adjustments. Ableton is only gonna use as many warp markers as it needs. If you’re music has tempo changes or is an acapella then obviously you’re going to want to use a different warp mode than just “beats”.
Unless you deleted all the transient makers somehow? Then just re-drop the song into a new clip slot and ableton should just give you a brand new pre-analyzed version.
