Create a Sinus Dimmer Phaser

This topic shows an example of how to create a sinus dimmer phaser.

It is recommended to read the Phasers topic and the Phaser Editor topic before this topic.

There are many ways to reach the same goal in grandMA3. This example uses a combination of keys and user interface. If you are working on an onPC, then it might be easier to write commands in the command line than using the on-screen keys.

Requirements:

• Have a show with some moving lights patched.
• An open Step Bar can be useful.
• An open Phaser Editor window is recommended.
• Arranging the fixtures in the 3D window can be useful, but it is not a requirement.

Follow these steps to create a sinus dimmer phaser:

1. Select all the fixtures: Fixture Thru Please.
2. Set them at a dimmer value of 0: At 0 Please.
3. Create step 2 and select it: MA + Next (Next Step).
4. Set the fixtures at full: Full.

This is the base for the phaser. There are now two steps with a dimmer value of 0 in the first step and a value of 100 in the second step. All the fixtures are changing together from step one to two in a linear direction and it does not fade using a sine curve. It looks like this in the Phaser Editor:

The curve is corrected by adjusting the acceleration and deceleration in both steps.

5. Select both steps: MA + Set (Step Toggle).
6. The steps need to have an accelerate value of -100. This is done using the Encoder Toolbar.
   1. Tap Dimmer to make sure it is selected.
   2. Tap Accel to select the accelerate layer.
   3. Tap the left-most encoder to open the Calculator.
   4. Tap +/- 1 0 0 Please.
7. Do the same for the Decel layer.

Now the attribute accelerates and decelerates out of and into each step. The curve now looks like this:

8. The final thing to do is to spread out the fixtures using the phase value. This is also done from the encoder toolbar.
   1. Tap Phase to select the phase layer.
   2. Tap the second encoder from the left - the one where the label says Dim(Phase) - to open the calculator.
   3. Tap 0 Thru 3 6 0 Please.

Now the fixtures are spread out equally over the entire phase of the loop.

This is a sinus phaser that can be stored in a cue or preset.

It is created using a specific selection of fixtures so remember to select the desired Preset Mode when storing a preset.
