I'm trying to use the Studiolive 16R as an USB interface and I've found that I can not rout the outputs directly from the DAW, I need to route them through the Universal Control Surface. I wouldn't have a problem to do that if I could assign USB as an input for the Flexi Mix output, but I couldn't find a way to do it, so I ended up having to assign the USB to an input channel, and from there to the FlexiMix. That's a partial solution that works fine till now for my needs since I'm not using the 16 inputs yet, but in the case that I need to get analog audio from the 16 inputs I wouldn't be able to use this method anymore, so I would like to know if there is a better solution to this problem. Thanks a lot!
PS: I've tried this in Studio One and Reaper, running on Windows 7, with Universal Control 220.127.116.11677 (latest version supported by Win7) and the latest firmware for the SL16R
