(Clip/Device/Track) sometimes it works, sometimes it doesn't, just try
User
- hold User button to adjust the sensitivity of Push’s velocity response and other settings (note: this didn't work in 9.0, the DVD version, if you don't get the menue update to the latest Live version)
Additional tips
- In Session mode, pressing Stop turns all Select Control switches that contain clips to red stop buttons (Track mode, additional infos here: viewtopic.php?p=1547117#p1547117)
- Since Live 9.1 you can select a single segment in the two Step Sequencer modes to edit it while the whole loop is playing (check this article for a detailed explanation:
https://www.ableton.com/en/articles/push-loop-playhead/). Keep in mind anyway that you could also duplicate the clip with the loop, go to Session mode, select the clip which is not playing (hold Select + press clip), go back to Step Sequencer mode an edit the clip while the duplicated one is playing.
