    data mixed - feeding 5 led strips with Teensy 3.2 & OctoWS2811 Adaptor

    Hi there,
    I have a setup of 5 LED strips, with 45 LEDs each (w2812b 5V) connected to Madmapper via teensy 3.2.
    Followed the tutorial for connecting via teensy and it works fine with 2 strips connected. Once I connect 3 or more strips at the same time I can see incorrect display on the strips. Looks like if the data from one strip is entering the others. Or if some LED remain on. Like a slow refresh. Data get mixed up or doesn't arrive well to the strips. Here link to video with 4 strips (you can see how some LEDs stay ON on the top and a black gap of OFF LEDs below.

    I did modify the arduino code for 2 lines adding up to 5 lines. Think maybe there may be a problem of handling the data... I'm attaching the code and my madmapper configuration.
    I'm planning on displaying an installation next Friday 21st in Barcelona and any support would be much appreciated ;)

    I'm feeding the 5 strips of total 225 LEDs with 5V and 30A through 1.5mm2 cables.

    Thanks
