What’s this manual thing you speak of vintage???
When I got my Sx2 upgrade from a behrinnger bcd3000, getting to know the layout and my workflow was my main priority, if I were you I’d get use to mixing across 3 decks without any effects or anything like that, slowly put in software effects then move onto flip, sampler etc I barely use the 4th deck i normally just put a jack into it and my phone connected as a back up, even when practising it’s good to be able to activate your rescue plan right?
Awesome piece of kit though good investment!
