It is more complicated than FL studio, which LMMS is I think would be much closer to FL studio.

Ardour is works better for recording. The MIDI editor works fine, it's just that LMMS has better MIDI editor. On Linux, Ardour is pretty convenience because it is integrated with JACK audio server. The recording editing is also feels better than Audacity.

I actually didn't use much Ardour when I was on Windows because it's was complicated to look at. But once I get to Linux I just slowly take time to understand what is what.
