Incorrect wiring for a DIY LED matrix?
Turns out I had to count the IC chips, not LEDs due to the fact I am working with WS2811 addressable strips.  So 51 LEDs vertically needed to be divided by 3 to get 17 chips.  Even more confusing, was that horizontally, it was still 12 LEDs in the software.  So for 612 LEDs, it was a matrix of 12X17.  Then it worked.  Hopefully anyone who ends up buying the k1000, T1000, etc and use LED Edit will find this answer if they are running into the same problem.  LED Edit desperately needs a manual and needs to add this clarification to the program.
