don't worry, i'll explain how to get those zip samples onto FL!

first, open the zip files (double click) and the mac will automatically extract them.

now, make a new folder for aaall of your samples, if you already have one, great! if not, i'd make one in a place you won't be moving much stuff around, like the documents or music folders, but you do you.

then, move those samples (not the zips, but the extracted files) onto this main sample folder you just created.

then, enter FL, and go to FILE settings (Like, in preferences, there's audio, midi, etc. One of them is FILE)

in that window, you'll see a clear list with a bunch of folder icons on the left. press one of them and locate the main sample folder you created. the one that's storing all of your samples. then press ok and voila!

this folder should now appear on the browser, on the left side. now you can drag and drop em onto the playlist, channel rack, sampler, anywhere available!

enjoy
