Hello all, I set up a simple project. Teensy 3.2, FASTLed and a 120 WS2813 strip connected to pin 2. When I run the FASTLed example Demoreel100 it works fine with default settings except the change from 6 to pin 2. If I change the number of Leds to 120 weird effects occur. Seems some calculation is of if the number of Leds is bigger then 64. From what I noticed the first 42 Leds are not activated/functioning. From Led 43 on strange effects are generated.

No problem if this firstline is added : #define FASTLED_ALLOW_INTERRUPTS 0.

Anyone else having this issue with more then 64 pixels and only FASTLed in use?
