Hi Professionals,

I'm simply working on my setup, every day it's getting better. Actually I think I did not really understand the functionality of a chaser using steps.

Example:

I Have an "Spider" (or how it's called) with three turnable bars. On these bars I can change the color of the LEDs and also the angle. Now I have created scenes, where only the angle of one bar is defined, Bar 1 -> 90° or Bar 2 -> 45° and so on. This should be change through ArtNet (every Beat), which is still working.

But I did not really understand the functionality of a chaser. To keep it flexible now I tried the following:

Step Szene Delay
1 Bar 1 90° 0ms
2 Bar 2 45° 0ms
3 Bar 3 0° here waiting for ArtNet-Impuls
4 Bar 1 45° 0ms
5 Bar 2 90° 0ms
6 Bar 3 45° here waiting for ArtNet-Impuls

My idea was to set the three different bars this way and wait for the next step, but I think it will not (and of course it did not) work. I though when a set an unit by DMX it keeps the values as it get's new ones, so why here only the steps 3 and 6 shows a reaction on the Spider, the other steps seemed to be ignored.

I'm (51) too old for that ... ;-)

Roger, you must see each "step" as a programm/function that - while it is "running" - keeps the values of a channel (or multiple) channels at the desired value.
When the "step" ends, no more values are "send" to the channels.
You can have multiple "programs" running simultaneously. In this case, QLC+ prefers the "highest value for a given channel" (HTP, Highest Takes Precence) over lower values.
Back to the chaser. Because every step is a "start function" / "end function", the values will go back to zero between step 1, step 2 and step 3.
Because, however, your "step 3" has a hold time > 0, you will notice a visible reaction of your fixture.
There are several solution which can be sucessful here. You can - for example - combine your scenes into a collection an and these collection to a chaser.
Or, you can create a scene to setup every channels of all involved fixtures at once.
Or you can change the channels from HTP to LTP. In this case you have to take care of the values all by yourself, which can be challenging on its owen...
Use the DMX monitor to observe your output.
HTH.
BTW, I´m 54 ;-)

Hi yokosuna,

aahhhhh, I think now I'm a great step closer ... ok, then I have to use the collections to combine the scenes.

I thought it was to much work, first scenes for the different possible things a unit like this "Spider" can do and then this ones into the collection and then into the chaser, I though it could be the easier way I described above, but hey, if it will work, I will do that this way.

Thank you very much, sometimes my questions are a little bit stupid for the professionals here, but only the "learning by doing (or experiment)"-way seems to be the best.

Bye
Roger
