In the wiki on parallel outputs it details the following option for the teensy 3.2:

WS2811_PORTDC - 16 pins

Does this mean 16 strips of leds? elsewhere it says 8 strips.

chipsets require two pins (clock and data) aside from WS2812/Neopixel and a few others… Im not sure if you can get to 16 strips if you are using a strip that only requires one pin…

Yes - ws2811_PORTDC will write out 16 lines in parallel. - @Mr_Happy the parallel output is specifically for chipsets like the ws2811/ws2812/neopixel. The fact that you can do 16 way output on some platforms is even documented here: https://github.com/FastLED/FastLED/wiki/Parallel-Output

Thank you for the information, that is interesting.
