I am currently working on a project with 4 strips of WS2812B leds and i’m using the Fire2012WithPalette example to run them. I have seen a post in the past explaining parallel outputs (i cant find it now) and im looking to see if someone has any examples that could help me run the same example on all 4 strips, but do it so they dont match identically. Im hoping to be able to just hook all the data lines into my controller and the timings and settings of each individual program will run independently. Thanks in advance

Maybe this example by Mark for running multiple animations at the same time will help.

TwoAnimationsAtTheSameTime.ino

#include "FastLED.h"

// TwoAnimationsAtTheSameTime
//   Example showing one way to run two different animations on
//   two different parts of one LED array at the same time.
//
// The three keys to success here are:
//
//   1. Move the drawing of each animation into a separate 'draw' function, 
//      each of which is called from 'loop()'.  Each 'draw' function draws

There’s this one by JP Roy running Fire2012 on 8 strips, all different too.
