Handling Focus

Hi everyone, it's great to be here and I hope it's ok that my first post is a range of questions on QLC!

It's kind of a complicated question but I'll try to keep it simple.

I have a range of lighting fixtures with focus control including a pair of Rogue RH1 fixtures. These fxtures can do beam and spot (as well as wash) and also have variable zoom ranges. I want to be able to have buttons to change to these different modes (probably buttons for the beam and spot gobos as well as small and large controls for zoom). They also have prisms which again require the unit to be refocussed. I could handle the focus with a matrix consisting of beam small, beam large, spot small and spot large on the X axis and Prism 1, Prism 2 and Prism 1+2 on the Y axis.

Is the any way to achieve functionality such as this in QLC? I'd prefer not to have millions of scenes for each focus scenario and have to call them individually everytime I pick a different gobo or zoom setting. Is it possible to create a script which constantly runs in the background and reads whether the fixture is in beam or spot mode, what zoom it's set to, and whether the prisms are engaged and set the focus to the correct value which I've stored in a matrix?

To complicate things further, I'll have some program that target walls and others the dance floor. Again each would need a different focus setting. Again, I'd prefer not to have to program this for every single scene I recall so I was hoping the script could just read a dummy DMX value set with movement scenes (perhaps using the address after the last used by the fixture) and again change focus accordingly.

Is there any way of doing the above in QLC? The alternative of programming this all in each independant scene just seems impossible. I do a massive range of venue and need a solution that is reasonably fast to enable.

If it can't be done in QLC, is there another solution I could use in tandem with QLC that can read the DMX values set by the program and change focus accordingly?

Thank you!

Lookup-table driven by feedback => I like this Jano

but we are lighting in 3D so X & Y should be involved also, but then again the lookup-table should be aware of this 3D-ness - ergo: a matrix lookup-table

Code: Select all

            Y+|
      Y+|     |
Y+|     |     |
  |     |     |
  |     |     0        focus
  |     0     |
  0     |     |
  |     |     |
  |     |   Y-|----------0----------     M /
  |    Y-|----------0----------       O /
Y-|----------0----------           O /
  X-                 X+          Z /
