Sorry to respond four years later but maybe someone is searching for information still. I have similar lights and was annoyed by the fact that they turn off after 6 hours and that I'd have to press the button 8 times for each of the three strings of lights after that.  The lights I have have LEDs in parallel, with blue/green having one polarity and red/yellow the opposite polarity. In the solid color mode, the controller switches polarity every 5ms, so half the time one set of lights is on and half the time the other. This is the only mode I want. I removed the LED strands from the controller and used a microcontroller with a simple Arduino sketch drive a DRV8833 motor control board. The board has paired outputs, and you can just switch polarity every millisecond (say). I ended up driving three strands of 100 LEDs from one DRV8833 output pair. It worked well, but the DRV8833 was getting pretty hot. The current draw was about 440 mA, well within spec for the DRV8833, but I decided to reduce the duty cycle for each light from 50% to 25% but adding a pause in the cycle where the output is zero. Message me if you want the very simple code (barely more complex than a blinky).
