Q Light Controller+

Hi!

I'm just learning to use QLC and I'm wondering if the product is powerful enough to do what I am hoping for.

I would like to be able to write scripts that can take a value of a virtual console control and store that to a variable. Then I would like to set various channels to a value that is a result of an expression (a combination of and/or and arithmetic expressions).

I'm also wondering if it supports basic conditional constructs like if/then and looping?

I'm crossing my fingers that this kind of thing is possible!

Thanks!

So .. AFAIK .. you cannot do this in the scripting console .. the primatives that are available are on this page: https://www.qlcplus.org/docs/html_en_EN ... ditor.html .. tho I can think of two ways you might consider

• using the RGB Matrix against your fixture(s) .. writing your own function ( using https://www.qlcplus.org/docs/html_en_EN ... ptapi.html ) and then you can programatically send values to the lights .. however not sure how you'd get an input to the matrix other than statically via a passed data encoded in the matrix .. there is a "dimmer control" option there but i've not played with it.
• I have done something similar by going external, using OLAd and intercepting the DMX values coming from QLC from one U and modifying them ( mainly H,V ) for joystick control of moving heads; and outputting on a different Universe. If you're interested in the code base it's a bit dated ( working now to convert to Python3 ) but you can find it here: https://github.com/sandinak/dmx-followspot .. but that could get you started.
• you *can* call external programs from "Scripts" .. I've used this with 'sendosc' to control OSC tools (Mitti) via cue's.. but I don't believe you can take data returned data and apply it; it'd be hella powerful if you could do this

Having more functionality in the scripts would be nice .. but would add some complexity having to deal with all the primatives.. might be easier if there was a way to pass data to/from external and apply it.

Good Luck
