Sub channels standard ?

Postby pace514 » Thu Dec 26, 2024 5:53 pm

Hi Claude !!!

I was wondering if thru all lightning companies sub channels are standard. I mean like CC 23 equal red., cc 24 equal green, C 25 equal blue, etc., etc. I've tried to find a chart with no success.

I asked because I'm trying to control the zoom/Iris/beam of a Colorado 2 Quad Zoom Tour. Using the osc message:/cmd.lxconsole/CC23 via a fader on TouchOSC, i can control the Red of any selected channel.
I thought using /cmd.lxconsole/CCzoom (or iris or beam) that I could control the zoom of the colorado.
Unfortunately, it doesn't work. Why ?

I take advantage of this post to Wish you happy holidays !

Thanks a lot !

Subchannels are a way that LXSeries software represents controllable parameters of a fixture. Various companies do this differently and there is no industry standard. In GDTF (General Device Type Format), which is newer than the original LXSeries design, parameters are called attributes and have names, not numbers.

In LXSeries, parameters or attributes are grouped with a channel by a number, independent of the name. So, the red parameter of channel six is 6.23. Within LXSeries, the numbers are standardized for many parameter/attribute types. So, all controllable red is assigned to subchannel number 23. In LXSeries, subchannel numbers were originally standardized and 500 was added for a fine subchannel. In later versions of LXSeries a subchannel has an independent resolution so there is only one subchannel for red (n.23) regardless of if it is 1 or 2 bytes, (if it has a fine component in the DMX output or not). The output resolution is defined in the patch for that subchannel. Currently, subchannels under 1000 are reserved to be defined in a standard way across LXSeries applications. Custom subchannels (1001 and up) can be re-used across different manufactures and may not have the same meaning for different fixtures.

To answer your question about OSC, you would use CC7 for spot and flood. This is controllable with the fader in the channel controls window. When the channel controls window is selected, you could also use CCBeam. The OSC address pattern would be /cmd.lxconsole/CC7 or /cmd.lxconsole/CCBeam and a single float argument with a value from 0 to 1.0 corresponding to 0 to 100%. This would control the spot/flood of channels that are selected in the main display. If you want to control a specific channel regardless of if it is selected, you would use (for channel eighteen for example) /cmd.lxconsole/18.7@%p
