I’m currently setting up my first home music studio and need help selecting the right interface to allow my to do the things I’m looking for. Right now I have a pair of ADAM audio A7x monitors, a Mac Studio, a Roland digital piano and an Axe FX guitar modeler. What I want to do is to be able to have all these equipment hook to the interface, so I can play backing tracks, record my guitar, play piano and have all sounds come out of my ADAM monitors. I want to get a UA Apollo interface, but don’t know which model I should get (I’m unclear as to how many audio inputs and outputs the interface should have). Anyway, recommendations you can provide will be much appreciated.
