Pioneer DJ DJM-900NXS2 is a widely used DJ mixer with 2 audio USB 
interfaces. Both have a MIDI controller, 10 playback and 12 capture 
channels. Audio endpoints are vendor-specific and 3 files need to be 
patched. All playback and capture channels work fine with all supported 
sample rates (44.1k, 48k, 96k). Patches are attached.
