I use to change colors in the programmer, when doing shows on the fly. In onPC2, I just set program-time, and the colors fade nicely from one to another.
As far as I can read in the manual for grandMA3, this should also apply for MA3 software. However, when setting programtime to zero, it just switch between colors, and as soon as I add program-time, the color just stays the same. Aka. nothing happens until I set the time to zero again. Am I missing something?
