I made my YouTube debut over two years ago, when I posted a dubstep demo performed entirely live on an iPad. No samples or tracks, just a drum machine and Animoog :) I recorded loops into Loopy HD and layered 3 or 4 tracks for a basic beat, bass wobble, and melody.
This little video now has 6,000 views over the months. I figured that means someone out there might like what I create. So I'm expanding on this, one small step at a time.
First step: start a blog. done.
