I would strongly suggest you DON’T buy the Microbook. I loved it and used it for years, but for whatever reason, the driver/interface now runs like garbage on several of my computers. It crapped out on me on a gig, and I had to borrow an interface from another act, which thankfully they had.
Feature/size wise, it was perfect for me, but it got to the point that I couldn’t trust it on stage. I upgraded to a RME, which is considerably more expensive, but it’s a frigging tank and reliable as shit.
