I’m in the process of converting my basement into a home studio. My pc is done but now I need an interface. I was looking at the aardvark Q10 or the Focusrite Octopre. What are the differences between both of these? I noticed the Q10 has midi inputs and the octopre doesn't. What does midi actually do and what do I need to use it? Sorry for so many questions, I’m just starting out. Jeremy
