Scrollers on 1.8

Hi Brent-

You can see DMX levels in the About screen under Background.

I just had a play with what you describe, and it seems to be OK here with a Revolution. I put the scroller in Frame 4 (from the encoder), and recorded CP4. I then go into fine mode and tweak the scroller, and use Calibrate. This is now the data for CP4 when I apply it again (I'm not sure that I should have to; I'll leave that to the experts to confirm.)

Does this line up with what you are seeing? Can you send a showfile if not? luke@etcconnect.com

Hi Luke,

What you tried was backwards.  We have not been using the Scroller encoder.  For the past two years, we have been using Color Palettes created two years ago from raw DMX values.  Those Palettes are on file on all our consoles, used by numerous operators and are in the possession of a couple of designers who use them in offline work.  I was hoping to make the transition to using the encoder a smooth if not unnoticeable one by keeping the original CPs and calibrating the frames to those values.

I don't have a file with me, but you could try this:  Make the CP first (slightly off a full frame) then use that to calibrate the frame.  Then go to the CP and see if the plus/minus sign is there.

I would think that that should work, shouldn't it?  If I have to start all over from scratch in the manner that you used I can, just thought I had an easier idea.

Anyway, my base file will have one calibrated scroller channel that is in all of the CPs.  I currently know how to copy that to other channels to make the CPs work, but I'm not sure how I will copy the calibratedness around.  After all, our scrollers all have the same deviation and it is impractical to calibrate each  frame for every show.

Thanks, B

OK, using the About window I have discovered that Calibrating a Scroller also changes the values in existing Color Palettes.  Why is that? 

Hi Brent-

Interesting - yes, I will have to look at it from that angle. I'll take a look tomorrow...I suspect that the answer is that you have to use [Chans] [RecallFrom] [CP], then calibrate.

Brent,

Sorry to butt in - does the physical scroller go to something slightly odd when you recall the colour palette - like part way into the frame beyond where it should be?

If it does, it would kinda make sense from my understanding of your problem. If your colour palette says (for instance) 4+ representing half way between frame 4 and frame 5 - frame 4.5 if you like - it might be intentional for a split effect. If the scroller drifts, or is swapped out for another unit, you may have to recalibrate where frames 4 and 5 are - but you haven't changed the '4.5' stored in your CP - ie you're telling it to be half way between where it thinks frame 4 is, and where it thinks frame 5 is. If you recalibrate and update the CP, that would solve it, I think? Hope that makes some kinda sense!

Apologies if I've misunderstood terribly

Dave,

We were using these scrollers on the Eos before the calibrate function.  I built the full frame Color Palettes from raw DMX values entered on the command line without using the encoders at all.  Therefore, two years later when I got around to calibrating the encoder frames, I didn't expect the CP values to change.  In general if I had built the CPs off of the encoder, I can see where it would be better for the CPs to auto update with calibration.  My situation is different but probably too esoteric to complain about (anymore).
