Isn't FL Studio a sort of a cross between CubaSE, LMMS and that other MIDI control thing on linux (Jack or something like that)? Looks an interesting program. Might look into it some more but for now I have pretty much all the bases covered with the above and audacity... If only I had the extra cash. In my case its either google for 'GPL' or license free music files or make it myself XD. Good luck.
