Amps First question - play a clip in the session view and it will override what is ‘playing’ for that track in the arrangement view. If you toggle between the two the track in the arrangement view will be greyed out. Click on the orange icon in the top right to switch back to the ‘recorded’ arrangement view track.
Second question - no the clips are separate. But you can create a further clip with in the session view with the now edited clip and move that to the session view. You can use '‘capture and insert scene’ in the create menu to do this in bulk to create a scene of clips from the arrangement view (a scene is a row of clips in the session view).
