when you use the nocturn’s automap in midi mode the possibilities are endless, basically each of the 4 banks (user, fx, inst, mixer ) can use (actually you are forced to use ) a different midi channel.
Once in that mode you can either create an automatic assignment ( and it will assign the knobs and buttons to all the different message a midi channel can have, so 127 cc’s plus all the notes, plus one pitchbend).
Or you can do it manually, you have several option for the the pots (normal, reverse, encoder, and you can set a min/max of the values it will send so you can have one with say : -64min / 63max, and it will put the knob in center = 0, like knobs on dj hardware).
And for the buttons, its cc’s or notes, with normal mode, toggle, and temporary, you can define the number of follow values in the automap too, so as to for example have a button or knob send 0-127 in only 10 steps, instead of 127 ( this allows to have much finer adjustements on knobs for example if you use 200 steps instead of 127).
Then you also have pages for each user banks, the pages can reach a high number if you use the “make automatic midi mapping”, because it will map all controls from a midi channel.
And for the leg rings, they are controlled by the automap, so if you change the page in the bank, or you go to another user bank, the led position is saved by the automap and directly recalled when you go back to it (no distinguishable latency).
The rings and buttons can receive traktor midi output led messages but if you want to display the phase, or volume, or something like that, you cannot use the knob to control anything due to conflicts (automap thinks that the incoming led messages are user generated, so, conflicts).
But because jumping between pages, and banks is very easy, you can dedicate one for all incoming led messages.
To wrap up, hiding and showing the automap window is also super fast/easy (dedicated button), and you can name the knobs and buttons when you set them up, so if in doubt of wich page your are in, or what button does what, pull up the automap screen, check that you are good to go and hide it.
