Using a physical controller with Traktor is great, but occasionally you can run out of buttons, knobs or faders. Instead of trying to weigh up the pros and cons of choosing a certain effect over another you can create something called a modifier. If you own a laptop you will have already used a modifier key. Usually these are labelled “fn” and will alter the Function keys (F1, F2 etc) to control things like volume and brightness.
The modifier key in Traktor works in the same way. You assign a button as a modifier and whenever this is pressed it can alter the functions of all the other controls.
Firstly open up the controller management page from the Preferences menu. Add a new assignment to the table and select Modifier > Modifier #1. Select the learn button and then press the MIDI button you want to use as a Modifier. Set the type of Controller to button and the interaction mode to HOLD. Finally change the “Set Value” to 1.
Now you can map 2 functions to each button or fader. Again add a new assignment and ask Traktor to learn the control. In order to set the function to work with the Modifier you need to make some further changes. Firstly set the Modifier condition to “M1″ and the Value to 1. This means that this specific function is only applicable if Modifier 1 = 1. When you hold down the Modifier button M1 will equal 1.
So next time you’re thinking you need a bigger controller why not try adding a Modifier or two and virtually increasing your size.Google+
