I thank Computer112 for discovering this Linux equivalent of FL studio and as for the program: I like it, but it has a tendency to crash from time to time. (A problem that plagues open source software, though Apache's Open Office is the epitome of quality assurance.) Here's some tutorials by Metalx1000 on YouTube:

Part One

Part Two

Part Three

Part Four

Speaking of Audio tutorials, I noticed that many of this site's musicians have made flash at some point. (Examples: Nav, StealthNice, Waterflame, DJ Harlock, Xarnor, ParagonX9, SmokeShow, and TheComet just to name a few.) Would it be nice if they teamed up and made a very comprehensive tutorial on FL Studio, Cubase, Reason, Studio One, Live, etc. (I already know that Nav did an FL Studio tutorial on trance drums and basslines, but want something more robust.)
