Yeah. Compared to most stuff on Newgrounds, I'm really oldschool in what i use to make music. That said, one of my upcoming projects will be a hardcore-influenced track. If you don't know hardcore by name, you'd probably recognize the style from bands like The Devil Wears Prada, I See Stars, and Underoath.
That said, it's really not a good idea to try and do hardcore on a sound system like FL Studio. If anything, it makes it really obvious that you aren't using real instruments (unless you recorded certain parts of your track, in which case you're in way better luck of pulling off the illusion). It sounds horrible (and if you already don't like hardcore, this will likely kill the genre for you).
The breakdown at the beginning's kinda nice, but it's really really terrible compared to using live instruments.
But yeah... Just a piece of advice; going hardcore? Stick with a real instrument.
