How do I save the samples I have selected on my S2 Mk3 controller with Traktor Pro 4? I have selected 2 Decks A and B as Tracks and C and D as Mixer on these 2 channels C and D. Every time I enter Samples, they are not saved every time I open the Pro 4 program. Is there a way to save them on the Samples keys? Can each sample I have selected be saved?
