YEah man! If you want the sounds to work together, get a rack... Buying a whole keyboard just to use in fruity loops is ridiculous... I got a triton and i sometimes use it to controll Fruity loops... But, it's much better to me as a stand-alone... You can always sequence in a program like Logic, Cubase, Pro-tools...
So if you want it to work with fruity loops (meaning sharing sounds with the fantom and fruity loops) get a rack... It would be way cheaper and make way more sense... Never buy a whole workstation unless you plan on learning it in and out... Who know's u may like usiong a Fantom keyboard better than fruity loops... It can happen, I tend to switch in between FL and my triton.. Now, I'm lovin the triton becuase you get a different feel when you can play everything and manually do drums, in my opinion...
