LED feedback from traktor pro (BCR2000, Nocturn, etc)

Hey guys,

I did some searching, but couldn't really find anything. Supposedly Traktor Pro has MIDI output for lighting lights and whatnot on the midi controller. My searching seemed to show that there are some problems with it though. My question is....has anyone got it to work?

I'm designing a custom MIDI controller, and I'm not sure if I want to do the significant amount of extra work to put in endless encoders with LED rings around them (like the Nocturn and BCR2000) or if I just want to put in simple pots with no LED feedback. Or if I just want to get a Nocturn or BCR2000.

I want to be able to, ideally:
1) See the position of whatever the knob's controlling by the position of the LED.
2) Change something in the software or by the keyboard and have it update status lights on the midi controller
3) Change banks so that the knob has a different function and have the LED ring update to show the new position of whatever it's controlling.

As far as I understand it, all of those should be possible according to Traktor's documentation. Which of those have been gotten to work?

Thanks for the help...

 

I was about to post a similar question. I cannot get the LED output to work correctly for me. I have pots with LEDs on my Killamix Mini and the midi output will change the lights when the software moves a virtual pot, but when I turn the Killamix pot it will only return to the center position and I can't move it from there. It just "twitches."
Otherwise it works fine as an absolute controller with soft-takeover.

 

here i posted it for the BCR

Yep, I just saw that thread. Thanks for the input. That answers my #1 there.

Can you confirm if my #2 and #3 work on your BCR 2000 too? In other words, if you change something on screen with your mouse does it move the LED on your BCR? And if you change banks/scenes on the BCR so that the knob now controls something else, does the LED change to match the new knob position?

 

#2 I can confirm: As I wrote in the other thread: You change the value with the mouse (or keyboard if you like) and the LEDs on the BCR will reflect that change.

#3 depends:
for instance the FX assignments: if you change to a new FX with a rotary that, lets say, controls your FX1 (unchained FX) the last settings (Parameters and Knobs) for that specific FX will be remembered by TSP and reflected into all Rotarys/LEDs Knobs/Leds that control the Params and Buttons of that advanced FX-1.
But if you have Volume for Deck A on a rotary, and on the same rotary (when pressing a shift key) PAN, TSP won’t display the current PAN Value on the LED-Ring until you start to rotate it.
It seems that for certain group of commands TSP “intelligently” flushes the current status of Sub-Parameters to the assigned LEDs if any new assignments has been made to the key control. FX Params are flushed when a new FX is assigned Deck EQs and VOLs are flushed if a new Track is loaded etc..

Changing Banks on the BCR:
I actually don’t use this feature any longer as those banks confuse me too much (always forget which one is active). But to achieve what you want I can advise as follows:
If in Bank “10” on a certain Rotary you assign “Volume Deck A” and then
in Bank “11” for the same physical Rotary but of course then with a different CH/CC Value is assigned “PAN Deck A” it should work the way you want: As soon as you select Bank “11” the LEDs shows the last PAN-value and if you change back to Bank “10” it will show the most recent VOL Value. But you see this is then not a functionality of TSP but a functionality of the BCR instead: The Trick is just to use aberrant MIDI CH/CCs for different Banks if you assign different Functions to identical Rotaries. The BCR then just “Remebers” the last value and initializes the LED accordingly.

Confused ? Try it out (a BCR is not as expensive as a Xone 4D ;-)
