I have an S4 mk3 just got, sorting out bugs or possibly a bad unit. . Audio drops out from S4 but everything else works and Traktor plays normal, master meter on software shows but s4 disappears.
Anywho….. In Traktor I can set audio to my built in laptop audio and still use controller just fine.
got me thinking…. With a usb audio interface … any dj geared ones out there that would have a main and monitor mix knob so you could cue like a normal mixer?
