I don't have the money to go out and buy a MIDI controller, but I want to make music on something like Fruity Loops.

If FL needs a MIDI controller, is there anything similar that doesn't.

It doesn't.
Yey short answer! Good luck with whatever you're gonna make in it.

Also I think there's some kind of trial for it (time-limit and unable to save works I think?), you could try that out just to make sure everything works 100%.
