Now I don't but I am definitely going to make one. Now reading musiety.com/the-best-audio-interfaces/ to choose a proper audio interface which is the main part and then I'll get Rokit monitors, midi keys and for now that's it. Some acoustic job also needs to be done but I'll deal with it later.
It sounds very interesting for me, cause I'm in love with music and I would like to make my own studio at home... Of course, it costs a lot, so I can't afford it now. My husband said that I can earn money for it on 888 slots. I tried it and I've won 800 dollars, it's incredible.
