I started watching my older brother do some weird green bar stuff in some dark colored program called FL Studio.
What was even weirder was it was making SOUND. Like, MUSIC SOUND.
I asked him to show me how and he did. We (as in him doing most of it and me writing a few parts) made a song and i borrowed his laptop a few times to do stuff on my own. I obviously sucked, because I was like 10 at the time, but it grew from there. When I got my own laptop I installed FL Studio and then just went from there. I'm 14 now and i'm way better. Nowadays you'll see me in some one time remix competitions like Zircon's RAR! remix competition or The Grand Robot Master ReMix battle. I'm also making an appearance in the grand maverick remix battle, so to anyone, be sure to follow along as i get better by miles.
As for other kinds of experience, I played trumpet only in 5th grade and I'm taking a protools/garageband course in high school at the moment. Other than that, though, everything is taught to me from OCR.
