Reversed CMY operation

[(iCe)]

For some reason the CMY channels on a HighEnd Studio spot 575 are inverted. So I have turn the wheel counter clockwise to increase the value instead of clockwise as usual. Not a really a problem, but for an upcoming gig I'll be using some Robe XT250 yokes as well, which don't work that way. So when I select both types, that becomes a bit of a problem.

I guess it's the personality of the HighEnd yokes which is different. Is there any reason for this? Can I change the personality file so it matches the operation on the Robes?

Do you mean the Studio Spot CMY?

If so, I have inverted the channels in the personality. Here is what I did:

from

Code: Select all

10 1  L 6  100 1L B 1 "Cyan"          255 255  0
10 61 L 7  100 1L D 1 "Magenta"       255 255 255
9  61 L 8  100 1L C 1 "Yellow"        255 255 255


to

Code: Select all

10 1  L 6  100 1I B 1 "Cyan"          255 255  0
10 61 L 7  100 1I D 1 "Magenta"       255 255 255
9  61 L 8  100 1I C 1 "Yellow"        255 255 255


I changed the 6th column from 1L to 1I.

This file will be available to download from tomorow morning. I will also e-mail it to you

Whoops, little mistake there... I was referring to Studio Color 575 yokes, not the spot version. Sorry for the inconveniance.

But I'll manage with above info to alter it myself I think.

Don't forget you can always do this manually using Patch Utilities/Invert.

Is that the same functionlality? Doesn't that just means 0 becomes 255 and the other way around? That would not entirely solve my problem since "locate fixture" would than mean: turn all flags in (and thus get no output).

I checked the fixture file and found:

10 1 L 7 100 1I B 1 "Cyan" 255 255 255
10 61 L 8 100 1I C 1 "Magenta" 255 255 0
9 61 L 9 100 1I D 1 "Yellow" 255 255 0

and changed the I of Inverted to N (Normal). I'll running it trough the sim now.

Altering the I into an N or reversed is exactly the same behaviour as inverting a channel in the patch utilities screen. That doesn't fix my problem.

The "locate fixture" value always is 0, and I have to turn the wheel counterclockwise to get it to 255. Inverted, the output of 0% becomes 255 and 100% becomes 0, but initially I still have to turn the wheel the wrong way.

I think it's the range table which is weird. It has the following formula for the CMY flags:

Code: Select all

RANGE 7  ;Cyan
0   255  "%3d%%""100-(((c-a)*100)/(b-a))
REND

RANGE 8  ;Magenta
0   255  "%3d%%""100-(((c-a)*100)/(b-a))
REND

RANGE 9 ;Yellow
0   255  "%3d%%""100-(((c-a)*100)/(b-a))
REND


For some reason the personality file swaps the entire channel around. Why is that?

[(iCe)]

Ah, that would be because on a Studio Color 0 = in and 255 = out.

I altered the file so it now matches my needs. On the display it says 0% for locate fixture value, but thats actually 255 on output. Turning the wheel clockwise increases the value to 100%, but decreases the actual output to 0 to turn in the flag.

I also did this on the shutter channel so it starts with "open" (output 248) and ends with "closed" (0) when turned clockwise.

It took some work, but now I understand these fixtures files too


Thanks for the assistance.

Just in case, the range table values are only for the text display relative to attribute value. The locate values are AFAIK defined by the 11th column (channel 'on' value), ie. the first number after the attribute name.

Jep I figured that out myself. The problem was indeed the displayed value which was completely inverted. Since I was testing on the simulator, I didn't notice the actual output was different, so that was what caused the confusion.

I fixed the problem by inverting the channel and inverting the locate fixture values. That way a locate fixture value of 0 becomes inverted to 255 and the wheels work like they should
