Running Studio One 5.1.1.61815 Win x64 (Built on Nov 13 2020), AudioBox iTwo atm - didn't work on Asio4all either. Updated version the other day and after that was when I noticed it - don't ask what the version prior was that I had, I didn't write it down. Basically looks like an issue with the track seeing the input from the plugins. I was able to record ezdrummer in ezd and then drag the clip into the drum tracks, and go from there, but it wouldn't record direct. Will also not record from Impact either, although in both cases the levels are plainly seen in the console.
