I'm a YouTube cover musician and as my channel grows I need to find an upgrade from my 2 track Behringer Xenyx. I'm a do it or don't guy, so I'm willing to spend some money. I've heard the Scarlett 18i20 are great for drums, and you can add the Focusrite Octopre to get 16 inputs. I use a standard size drum kit, and on occasion a huge double bass kit with 7 toms, but I think I could mic it all if I had the Interface and the Octopre. Anyone think this is a good set-up and if not any recommendations?
