Good point about the "Live" hint. I don't see SONAR going with the plan to be a live performance tool anytime soon.
Not only the live point, but these midi Pad controllers are meant to be used in a work-flow such that you can turn on and off notes while composing music. I just can't get a good workflow going with this new controller with SONAR yet and it seems I won't be able to unless some of these new features to support them are added.
