Hi,
I was also not able to use my Scarlet interface at first (18i20 in my case). I had it working using aggregate device and it was kind of usable. My problem with that solution for me was that my ADAT inputs had some weird issues (input not lining up properly, noisy buzz on working inputs, etc.) but it might be a working alternative for you as you don’t have any ADAT ports on the 2i2. So for my part I decided to give some other DAW a run while Steinberg fix the issue. By the way, the interface is working flawlessly in Studio One… I’m actually trying the demo of Studio One 3 and I seriously considering getting it as they offer it as a crossgrade. I could use it as a fallback DAW as I still prefer the features in Cubase, but I find them very slow to follow upgrades and all… and plus there is no dongle to put up with!
I found the instructions somewhere in this forum; here is the link to the post:
Hope this help!
