The mapping on FL Studio is completely different from Ableton Live in terms of browsing through the DAW, there are even stickers to put on the Launchpad so it can guide you on FL Studio.
There is an interesting design on the mapping for FL Studio, unlike Ableton Live you don't have control of your mixer, instead it uses a several different pages of mappings, for example there is a page where it displays a 49 keys piano keyboard, a page to play with the FPC, highlighting the pads and faders, another one with just vertical or horizontal faders to assign and so on.
The best thing about this pages they are completely customizable, you can for example create a 25 keys keyboard with 4 horizontal faders, you can also create pages with DAW controls, you can check on how to do this on the link below.
It works exactly the same way as Ableton Live but in a horizontal layout.
Light show works the exact same way as in Ableton Live using a MIDI Out and building the sequence of the notes with the piano roll, but in order to activate the light show, you have to put a note on G10, this will disable the lights of the standard layout, I will link a video on how to do this below.
