I am using Studio One with a Focusrite Scarlette 18i8. I have 4 microphones plugged into it. I can see all 4 on the mixer software for the Scarlette, all give sound. I downloaded a free piece of software, and it can see all 4 mics, but I can't get the Studio One to see Mic 3 and 4. I try to add them in the under Song Setup. It sees them as an option, but clicking on the square under 3 or 4 brings up a greyed out M. As soon as I click Apply, it disappears again.
Is there a setting I'm overlooking to get this to work?
Follow up: Yes, I am very sure I checked under Song Setup. I can get it to work with Mic 1 & 2, just not 3 & 4.
