In the final stages of finishing my singing faces and connected up a 27 Channel controller. When I applied power all the pixels lit up. There are 8 circuits with Dumb RGB's so 24 outputs used. Running 5V supply. (Ah i think somewhere 5V is too low to run these boards)... I digress. THE Freaky part is that when I looked at the lights they were all at the correct colour...NO controller and all DIP switches off.
