no that's it, you can get multichannels with asio drivers only,
the othere ones are separated pairs

[dac 1 2 3 4] are analog out, adat should be the last eight outputs

yes, usually it works, but with using [vst~] I have more chance to make it working when windows isn't using RME drivers

yes this strange order is a reason why there should be something else to always get the same device
but it's more a job for the devs
