Regarding routing ableton to traktor.
I made a thread about this before, saw the posts and read the tutorials. What im wondering now is external mixing, how i’m i supposed to control the tracks volumes in traktor with my s2 when i have no control over them? Do i need to map something to ableton and control it from there? What about cue’ing my tracks on my headphones and all that?
Are you talking about the thread you opened this morning?
Map in ableton.
you need to (as mentioned above) map the faders in ableton live, to do this you will need another controller or need to have the S2 in midi mode (shift + shift). i am currently doing the exact same thing and am working on a midi mode map but i am not to good with the traktor mapping system so its gonna take a while, but afterwards i am hoping to achieve basic 4 deck control, jog fx, and the entire mixer section mapped to ableton live. hoping this all goes well of coarse 
keen to see what other responses get posted here.
i guess you need to use the S2 in midi mode mapped to the controls in ableton - and use the HID mode for other traktor stuff. you’ll need to do the headphone cue’ing in ableton if you’re using external mixer mode in traktor.
for cueing in ableton select a different output for “Cue Out” for your master output and then click on the “solo” button to turn it into a cue. simple 
Isnt that a lot of work to do live? I bought controllers to stay as far away from the pc as possible, can i map something for the cueing in ableton?
holds hand
Search “cueing in ableton” in good ol’ google. First hit should help.
If you’re using Ableton and hoping to stay away from the computer, I’ve got bad news for you.
it’s only a one time thing - same as having to select audio setup in traktor. most things are mappable in ableton and get saved with the live set. so once u have it setup, map buttons on your controller to control the cueing (which is much simpler than mapping in traktor anyway) and job done… from then on it’s midi all the way…
don’t see why. what cant u midi map that you’d need to in ableton?
edit: i know u need to use max4live for some cunning things - but most of it is available and very simple to map
The most intricate mapping in the world can’t give you feedback on a controller, short of a Maschine. Mouse use =/= screenwatching.
no biggie for a fader or something - as you have the fader itself. clip status u can feedback via midi tracks. can’t u map the input of a controller back to itself via a new midi track? i’m new to traktor so apols for dumb questions. feeding the output from a controller back into itself in some form isn’t an issue for me anyway tho as i’m using midimasher to sit between my controllers and traktor+ableton.
What I’m saying is that you could have a huge knob bank with LEDs, or pads in a similar way, but there’s no way for the controller to tell you what that knob is actually mapped to. If you have a layered mapping, the mess compounds, especially in an application like Ableton where everything isn’t laid out in a grid of knobs. You’re basically going to have to screenwatch to keep up with your mapping.
easy in midimasher - i just use different colours on each launchpad pad for example to show me what the layout is. or are u referring to the midi feedback from ableton to to make the led change when something happens inside ableton itself?
I’m talking about when there’s 8 unlabeled knobs in front of you, figuring out which one controls what, while performing. Likewise with the clip launcher, unless you’ve got an 8x8 grid of samples completely memorized, you’re going to have to use the screen to figure out what’s what at some point.
sure - but traktor is no different surely? u can map a dj/mixer style controller to ableton just as well as to traktor or vdj (tho vdj has a lot of extra mapping goodness available ) so u should only need the midi controller as frame of reference.
i have this all setup and working, the only problem that i have, but am sorrting out is the midi mode on the kontrol s2, its not practical to keep switching between HID and midi mode, so you need to create a full custom map of the s2 in midi mode but leave the mixer section for mapping ableton, then there you map your eqs,faders and so only and even your monitor cue. this way you will have the complete function of the s2 as it would be in traktor and have access to abletons clips and fx and so on…
that won’t work or shouldn’t - as the S2’s midi can only be attached to either ableton or traktor - not both at the same time. unless u use bomes or something to route to both of them. also isn’t it better to have the jogs in hid mode?
it does work, well for me at least. i added it as a generic device and i have only started testing with basic transport controls and have not gotten to the jogs yet, the resolution wont be as good as in HID mode but im sure it cant be terrible or unusable.
interesting… i’ve never been able to open a device for read/write from two apps at the same time. i’ll have to try it later with some controller.
Traktor is DJing software, for playing up to 4 tracks of linear music in one dimension. Live is a production performance software, designed to manage, launch, and modulate dozens of samples and parameters per scene. A VCI-100 isn’t going to map to Live like it does in Traktor, and the result of using Live in a performance type situation isnt really “DJing.” Controlling an effects chain, Massive’s macros, a drum rack, and a sample grid across 1-2 control banks, and keeping track of whats what isn’t quite the same as layering hot cues and sample deck controls with a colour code.
