nice. I been using FL Studio for the last 5 years or so. its pretty handy once you figure the essentials out and theres a lot more to it then most people think
just keep exploring the plug in (compressors, vsts, eqs and what not) then branch out from the stock sounds and gather up a bunch of your own unique drum kits.
I think its best to build up your own library of drum sounds, and work with those. but there are plenty of drum kits you can download, just doesn't have an authentic vibe like when you create your own
