I'm running Windows 10, using the Traktor S4 as my main playback device and as my audio interface.
Traktor is set to WASAPI Exclusive @ 96000Hz and I can play audio to my speakers just fine out of the decks in Traktor.
I have a Maschine with the USB routed into the USB hub on the Traktor, and the driver and device preferences are set to WASAPI Exclusive and Traktor S4. The Routings for Maschine Output that are available are the S4 Main/Booth L and R and the Headphones, L and R. I'm sending the Maschine Out 1 L and Maschine Out 1 R to the Main/Booth L and R Ports.
I feel like I must be missing something simple here. I had it working before, both with and without a MIDI send/receive from Traktor -> Maschine.
If anyone can figure this one out I would much appreciate it! Thanks 😀
