VCI100 - Traktor3 - 2 decks 2 samplers
my map (with a handy picture of the buttons).
Put it together as was looking for an easier way of using all 4 traktor decks without constant swapping/toggling of deck controls and also wanted dedicated fx controls for each deck (a and b).
As i only ever really used the bass knob (always have ever since starting on vinyl 10 years ago) i opted to use them as fx controls, and turned the fx section into sampler controls.
