The first 4 modes can be triggered by pressing the performance pad mode button of the same name once, and consist of:
HOT CUE mode: Pads 1-4 trigger Serato DJ Lite Cue points, and if no Cue point is present on that slot/pad, pressing that pad will set a Cue point. Holding down the SHIFT button while pressing a populated pad will delete the Cue point from the respective pad/slot.
