Phaser padding with release values

  • Hello Forum,

    I don't know if this is a bug but it is not what I would expect.

    I have a phaser with a "clap" effect:

    Step 1: White, 100%, Width 10, Transition 0

    Step 2: Release, Release, Width 90, Transition 0

    Now I want this effect in different lengths without affecting the length of the clap.

    To do this I add a 3th step with a width of 0 which can be changed to introduce padding to the phaser

    Step 1: White, 100%, Width 10, Transition 0

    Step 2: Release, Release, Width 90, Transition 0

    Step 3: Release, Release, 0%, Transition 0

    When I change the width of step 3 it does not respect the length of the clap.

    I would expect the white clap always be a width of 10

    Could this has to do with the release values?

    In the attachments I have added a showfile to debug.

    Execute Edit Preset 21.1 then in the phaser editor change the width of step 3 to 700 for example and check the color in the grid layout

  • I have created a very simple macro to demonstrate the problem.

    Make sure Fixture 1 is patched and the default color is white so when turning on the dimmer there is color output.

    Code
    Fixture 1;
    Attribute Dimmer At 100 Width 10;
    Next Step;
    Attribute Dimmer At Release Width 90;
    Next Step;
    Attribute Dimmer At Release Width 0;
    Step 1 Thru 3 Transition 0;

    One liner: Fixture 1; Attribute Dimmer At 100 Width 10; Next Step; Attribute Dimmer At Release Width 90; Next Step; Attribute Dimmer At Release Width 0; Step 1 Thru 3 Transition 0;

    Code
    Fixture 1;
    Attribute Dimmer At 100 Width 10;
    Next Step;
    Attribute Dimmer At Release Width 90;
    Next Step;
    Attribute Dimmer At Release Width 800;
    Step 1 Thru 3 Transition 0;

    One liner: Fixture 1; Attribute Dimmer At 100 Width 10; Next Step; Attribute Dimmer At Release Width 90; Next Step; Attribute Dimmer At Release Width 800; Step 1 Thru 3 Transition 0;

    Why is the length of the color output not the same?

  • Use the Measure layer.

    • Without a Measure value, the duration of the loop is variable, based on the sum of the step widths.
    • With a Measure value, the duration of the loop is fixed, and adjusting step widths only changes the relative duration of each step compared to the others.
