I was recently offered a Mackie MCU Pro at a nice price and figured I'd pick it up and see if I could learn my way around on it. Integration with Logic X was painless and easy. I've learned probably 20% of the available features, so it's hard to say whether or not this is going to be a permanent piece of my setup. I still find myself using my keyboard and mouse a lot because that's what I'm used to. I need to really dig in and learn this thing if it's going to be much use to me. Anyone else gone down this road? Long-term satisfaction?
