Im in the process of recording my first mix in Trakor and am still a little unclear about the "audio device and built in soundcard" sections in Traktor. When i mix i usually set the mixtrack pro as audio device and the built in sound card and connect the mixtrack to my receiver, but this leaves me unable to adjust the sample rate. When i use ASIO4allv2 the main channel comes out of the speakers on my laptop instead of my surround sound system and i AM able to adjust sample rate. But regardless of the device set up i am unable to adjust the latency sliding bar under "sample rate". Im just trying to get the best quality recording for my mix, If any one could give me any type of advice or info about this section i would GREATLY appreciate it.
