1. yes, if you set a track to a particular midi channel you can play it externally, chromatically, no matter what mode you are in.

  2. yes, except for the tracks that are binded together.

  3. not %100 sure, but I think you can.

  4. Sort of. You cant really “trigger” slices, more like select slices using knobs, CC, or Scenes/Perf modes, then trigger the pad.

Hope that helps.
