Hi Guys Is there a method in Logic to allow the user to adjust the ramp time of a GA? I'd like to have a button/s or slider on a Wiser 2 iPad interface to allow the user to adjust the ramp time of a group address. The ramp time would stay the same until the user wished to adjust it from its current value. I'm thinking some sort of system variable that is set and recalled in logic. The GA would ramp up and down each day via a schedule or triggered manually by the user. They would be very long ramp times 30-90 minutes. The user is simulating sunrise and sunset in a commercial environment using artificial lighting. Any assistance would be appreciated. Cheers
