EDIT: here's a second track looking for feedback:

I have no internet, or cable at my new apartment yet.

However, in the meantime, I seem to have been blessed with a lot of musical inspiration as of late.

Maybe the two are connected?

Anyhoo, here's a piece that i pretty much spent two straight hours on last night and am posting here at my school library after my work shift.

I decided, as it says in the description, that it was finally the time to start figuring out samples/sample libraries, and the various filter effects, and whatnot (it's not like I never used either before- I did, but it was never a focus of composition to incorporate them). If I want to make the music I REALLY wanna make I'll need to get proficient in all of these and much more.

So I open this piece up for constructive critique, or well-wishing adulation. I'm fine with either. Fixing the piece is as simple as opening up FL9 again, but I'll let the more musically-proficient analyze it.

A bump because I have another track I'd like to have people look at, if possible:

Basically, it's more of me trying to get myself to learn how to use samples, filter effects, and whatnot more effectively; finding my "voice" you could say.

Turned out really good, as a matter of fact. But hey I'm biased.
