RTFM, I know. My setup my be complicated, but not really. I originally was going to set this up to run on two MacPros connected via ethernet. But, for now at least, it's running on one. I'm just trying to run one upright bass preset through Vienna Ensemble Service. I see the instrument. The meters are moving. I've chosen the correct output pair, but the sound isn't getting to the interface. VEP 5. Sample rate 96k.
Yosemite 10.10.5. DP 9.51. Metric Halo ULN-8. Any ideas off the tops of anyone's heads? What am I missing?
