Hello everybody... :) I've a question about "Mirroring Strips" ...

Hello everybody… :slight_smile:
I’ve a question about “Mirroring Strips” … I would like to control 480 WS2812 leds (4 x 120 led 2 mt long strips) all connected to an Arduino 1. I’ve read that it’s possible to wire each strip separately to an Arduino Pin ( https://github.com/FastLED/FastLED/wiki/Multiple-Controller-Examples ) and then show the SAME effect on all strips via Show() function.
Is it also possible to SWITCH ON/OFF each strip line separately ?
