Blade Control Separate Topic. Control 2 channels with one parameter [DDF]

We proudly present: The release of DMXControl 3.3.3!


On September 29, 2026, we held our release show for DMXControl 3.3.3. During our usual “hour-long” session, we showed you all the new features in this version and what it now has to offer.

  • Good Day All!

    So today I have the chance to play around with a fixture with blades again.

    I have discovered a way the blades on this particular fixture work:

    Each blade has 2 parameters. Example:

    Ch. 18. Blade 1_A

    Ch. 19. Blade 1_B

    At first I was losing my mind, because The blade would not work linearly.

    Then I realized. In order to make the blade move linearly (Straight Up and Down) Both Ch. 18 and Ch. 19 must be operated at the same time.

    To rotate one way or another, Blade 1_A or 1_B would have to be adjusted individually.

    So it pivots from each corner.

    Now I know currently the syntaxt for Blade control is a bit limited, but it begs 2 questions.

    1. With the current blade control syntax, is it possible to program the DDF to behave in this way (Rotation and movement based on left and right blade rotation/movement), rather than one channel for linear movement, and another channel with range to control rotation on center?

    2. If that is not possible, can a RAW channel be created that simultaneously effects 2 channels with one slider or Parameter change?

  • Hello!

    Please check out again the article about the blades in our Wiki. I added there the variant that you could need.

    But please note, that this variant just offer moving all blades without any angles. So far your fixture would support to move the blade also not parallel, you won’t currently be able to create forms like triangles or trapezoids for example.

  • Hey Stefan. Again thank you!

    Haha. I can't believe I didn't think to try this. I must have attempted every other combination of random syntax. Lolol.

    Could the same method in a sense apply to a RAW channel if you define the samesay

    <raw name="x" dmxchannel="0"/>

    <raw name="x" dmxchannel="1"/>


    Hmmm.... This one fixture feature does make it quite the anomaly to integrate. Lol

    Another fixture I will be making a ddf for soon also has blades, but uses the exact syntax that already existed.

    Again, I am working on a special project and integration.

    I will make all my information and findings available once everything assembles and is thoroughly tested.

    I hope to demonstrate to certain industries here in my area that DMXC could in fact become a new industry standard.

    I truly believe in this project, it's functionality, efficiency, and the team working to make it what it is.

    This is lighting done right.

    And again bravo. And thank you again.

  • Here is a sneak peak of Network and stabilize testing of the common control surface I am working to integrate.
