Hey Yonny V, welcome to the forums. Quite a few interesting questions. First we need good definitions of what is a DJ and what a producer. The two are not mutually exclusive, so you can do both. They are however so different that gear, software, technique and knowledge and skills don’t carry over much either way. I would not suggest starting on both avenues at once. The main question you have to ask yourself is: “do I want to make my own music and share that with the world the way all music is shared, or do I want to take other peoples music and use that to take people on a musical journey as they dance and enjoy a nice evening”? If you want to make your own music, then producing would be the direction to start with, otherwise going into DJ-ing makes more sense.
The waters are muddied though, lots of DJs I would actually consider producers or live-performers, so it’s not all cut and dried.
What I CAN say is that it pays to get education. It will shorten and flatten your learning curve and start you off practicing best-practice ways of doing things which beats figuring things out yourself with trial-and-error and having to first un-learn a bad habit to then replace it with a good habit.
Good thing is that you can find courses at Digital DJ Tips like How To Digital DJ Fast (4 weeks could have you ready to play your first b’day party 😀 ) and Music Production for DJs. As they are money-back guarantee they offer a low-risk proposition.
