Are you sure those were samples? I think the point of it was that it was completely played by the people who made it. Hathbanger usually just does sampled stuff, but I assumed this was completely original.
Not sure how a keyboard and drum machine make your rhythms unoriginal - a drum machine is just a tool to let you express yourself musically. You may not have to play drums to use it, but you're still creating it. Or are you saying that even individual sampled drum sounds triggered by pressing a button make it unoriginal? That would invalidate a whole lot of music.
Anyways, sick edit, sick track. Keep it up, I look forward to seeing more.
