I used to think the Piano Roll in FL was too complicated. I hadn't even tried it.
Anyway, if you download Norman Cook- Skip to My Loops (found it reuploaded somewhere on Reddit), and go to STABS, pick 073_COOK and replace any of the 4 sounds that are preset in the channel rack (or just create a new one). You might recognise this sound from Jet Set Radio, apparently it's used there (I haven't played it yet I'm trusting the internet). Now go to Piano Roll. Make 073_COOK the sound on it. Then open the playlist (that way I can tell you the right intervals).
On Piano Roll, place a G#1/20 sound, the initial note. Now place a C2/24 6 playlist rectangles after. Just for this, I'll see how many piano roll squares it takes. (it takes 28 squares on a default zoom Piano Roll, from the end of the first sound thing, to the start of the second). Now put it as a pattern, place a couple patterns right after, and done! You can do whatever you want with this. If you already knew this, sorry for the wasted time, if not, well now you can make Meatophobia!
Meatophobia is the song from Pizza Tower that plays when you're next to a John Pillar. Here's the Spotify album link:
