[Interest] Problem with changing duration property in a sequential animation

[jim]

Hi I have a SequentialAnimation containing a number of ColorAnimations
in an infinite loop. I want to update the duration properties in the
ColorAnimations with a slider.

ie. duration : sliderHorizontal1.value

This works only after I restart the animation. I want the animation to
change speeds while it is running as I move the slider. Is this
possible? A snippet of my current code is below.

Thanks

Slider {
        id: sliderHorizontal1
        x: 55
        y: 425
        minimumValue: 100
        value: 100
        maximumValue: 2000
         onValueChanged: text1.text=Math.round(value);
    }
 
    SequentialAnimation {
        loops:Animation.Infinite
        id: playbanner
        ColorAnimation {
            id:cA1
            target: rect1
            property: "color"
            from: "black"
            to: "white"
           duration: sliderHorizontal1.value
        }
        ColorAnimation {
            target: rect1
            property: "color"
            from: "white"
            to: "black"
            duration: sliderHorizontal1.value
        }
        ColorAnimation {
            target: rect2
            property: "color"
            from: "black"
            to: "white"
            duration: sliderHorizontal1.value
        }
