This thread makes me lol.
To be fair, a good portion of the drum presets in FL are based on the synths/drum machines (such as the 808) that literally MADE the genre of hip-hop. If you want, use a pulse wave instead of a sine, i'm sure the bass will sound just as fantastic (sarcasm).
Making beats from scratch is fun, sampling dusty-ass records you found in the bargain bin at your local record store and making your own stuff to layer atop it is equally as fun. I prefer the latter, personally.
But honestly, does it really matter how you make a track? The final product is what really counts: if it's a representation of your musical spirit and it gets people's head bobbin at the same time, then you killed 2 birds with 1 stone.
I appreciate the dirty south, west coast, and more mainstream sounding producers on NG, because they don't what I DON'T do, and there are many hot tracks coming from them.
It's not really up to the artist to choose their music style. The style chooses them. But limiting yourself to just that one and ignoring the others.. that's the problem.
