So I'm looking for some info on how traktor interprets "high resolution" controller messages.

First, what protocol do controllers use? ISsit all/mostly HiD, or is there more diversity than that?

Is Traktor at all capable of using these messages, or does it just convert them to midi values?

What if you put a S4 in midi mode? Does it still read the hi-resolution inputs, or does it only send midi?

What about the upcoming behringer CMD PL-1? It will include a high-resolution pitch fader and jogwheel. Will traktor be able to take advantage of these?
