How do i use pre-cuing with my macbook pro & a Tascam US 100 external sound card?

I’m connecting my external USB interface (Tascam US 100) to my macbook pro, however, it’s not recognizing the device and when i click on the pre cuing icon, it says that pre-cuing is not supported with my current audio device setup. I have a gig on saturday and really need this thing to work. Ideas?

Hi Wayne,

Does your sound card show up as one of the options for Pre-cueing (or Main output)? What is your current Devices setup? And also, which djay version are you using?
