Looking to make an array with multiple led strips on different pins on my Arduino but have the light continue to each strip like one large array, I know this is possible with the FastLED library but wondering if it is also possible with the Adafruit library as well.
You can wire strips end to end with wire long enough that they are not physically close (look like an array) and use one pin.
"with all humbleness I wonder why people still recommend to use the Adafruit library."

Adafruit_NeoPixel vs. FastLED - LEDs and Multiplexing - Arduino Forum
There was a recent post (beginning of the year?) by a frequent contributor who was looking for something that did exist in the NeoPixel library but did not exist in the FastLed library.
But the NeoPixel library missed something else that was available in the FastLed library.
I think he/she eventually decided to copy the additional needed functionality from the FastLed library into the NeoPixel library so he/she could use the the needed functionality of the NeoPixel library because it was easier than the other way around.
Did you read about what the Adafruit library does to interrupts? Try millis timing with it!
I use FastLed because I'm not ready to mess with the timing that WS28xx needs but I make my own effects after looking at the featurism of FastLed.

I would just go from end to end but the problem i face is that strip 1 will use ws2812 led's with GRB configuration while strip 2 will be 12mm ws2811 leds in RGB configuration, i need to be able to specify two strips in order to match the correct RGB configuration for each strip. I would use all ws2812 led's if they made a 12mm led which is what i need for my project.

Do you think it may be able to copy the multi led array portion from the FastLED library into the Adafruit Library?
I have no idea.
2 pins then and a lot of 5V, or at least my Wesiri WS2811 12mm diffused RGB led strings are 5V.
I read that with WS2812 that if one element dies (leds are not forever) the rest of the strip gets no signal so now they have WS2813.
You can get WS2812 elements in break-apart sheets and put light diffuser bulbs over them?
Why not go with all 2811s?

I meant go with all WS2812 by rewiring the strip so the leds are far enough apart to put diffusers over -- like the WS2811 bulbs have longer wires between each. Put the now-it's-a-string-not-a-strip under a light diffuser and you get big pixels out of WS2812. You can buy sheets of WS2812 elements 10x10 and wire them how you want. People put then in clothes. The wiring must be a pain.
On led strip the leds are too close but hey if you only light every other one they wont blend by the time the dots get 12mm wide. Make it every 3rd and you could get smooth moving lights.
Yes 2 pins. 1 for each WS type. How many leds each?
