If your good at keyboards, and have a nice keyboard, stick to it, you'll do better with it than with shit on Fl Studio...but I would suggest learning how to transfer shit back and forth from Fruity loops, Acid, Or Reason, Whatever The Fuck You Wanna Use, So in case you wanna use certain samples you can and you can be more professional with beats and effects probably on Fl Studio or Reason, etc.
