A DJ friend of mine has some contacts at a supplier. He said that there are some new rumors about the upcoming soundcards from Native Instruments. They are to be launched pretty soon!
The two new soundcards are meant for the new upcoming software and will have 3 and 5 stereo inputs and outputs. Apearently the new system will have some kind of aux functions and will be pretty close to Traktor S4, but it will be tailored for both Timecode and Controller-freaks!
