THat is REALLY good. However a few of those steps require years of work and study. I think so many people think they can simply learn to use some software and instantly they will be a music producer.
But you know, it gets worse. Even if you can play piano, bass and guitar and have studied music and you own and know how to run all kinds of studio gear thaere is still one thing you need: Artistic judgement and "something to say"
In fact you don't need to know anything technical. You don't need studio equipment and yo don't need to know the difference between 3/4 and 4/4 time because you can hire people who know all of that. You can hire studio musicans and engineers and whoever but you NEDD to know what the end product you want is, what sound you are after.
But realistically you will need to be knowagable in all aspects of the process. You need to be at least intermediate level musician and know enough about studio recording so you can talk to an expert using his terms.
The best way to get there? Work your way up from the bottom
Best way to become a music producer is by starting to produce music. Use whatever equipment or gear you have/can. Use the above site and other resources ( like Google ) to help in your journey and take it from there.
