Hi,
simply give any address to your controller and then on your desk put any values to that address and few next. Usually led bars works in two or three modes: RGB, chases and automatic. THe first mode uses only three channels and the value of the very first says what mode is used. You have to combine and observe the effects and than write a template.
Nothing is impossible but it costs a lot of work and time.

Greets, Andrzej.
