I have tried switching to Studio One 4 Prime to record live shows using my Focusrite Scarlett 18i20 (Gen 1). However, the I/O input matrix only lets me use Mic 1 and 2: When trying to use another input, the box is greyed out and disappears when hitting apply.
I have tried using both the "Focusrite USB 2.0 Audio Driver" as well as "ASIO4ALL v2", but the same problem occurs. The last time I used the Scarlett was roughly half a year ago on a Mac, which worked perfectly, so I am almost sure the device itself is fine.
Does any of you have any ideas? Sadly, I don't have access to the Mac anymore, so I need a solution that works on Windows...
