I’m struggling with this as well. I have an API 2500 and a UBK Clariphonic. It seems much easier (and intuitive) just to insert them on the Master Bus in Cubase and then assign that bus as an input and record the result on a Stereo channel. My studio is being renovated, and I just bought the 2500 and Clariphonic. So, I haven’t done it. I don’t know what the downside to doing this is, and would appreciate others chiming in. It seems to me an unnecessary step to go through TotalMix for routing, unless the Summing Engine is better
I know some folks like to sum through an analogue mixer because they like the colouration it can give to the mix. The digital summing in the Cubendo audio engine is as near perfect as anyone would need in this life.
Summing in the digital domain is a bit pointless, the whole debate about the benefits of summing concentrates on analogue summing which is why companies like Manley produce summing mixers at huge cost to buy. It debatable if it makes a difference, I think it does but not as much as running you’re finished 2 track though an analogue tape machine, and even then you might like the original better.
There’s a full page dedicated to using Loopback mode in my RME manual. Important thing to note which I didn’t find in the book is that you have to have ASIO direct monitoring off in the TotalMix otherwise you can’t put the hardware output channels into loopback mode.
went a little nuts wondering why i couldn’t arm loopback mode on my totalmix outputs
