Hey all,

I didn't want to post this in Bugs because my experience is that is usually something that I am doing wrong... So, I've been using xLights for several years.  Been using pixels and pixel controllers for 5-6 years... what does that mean?  Absolutely nothing because I can't figure out this current issue I'm having!   :D    I have five songs updated for our display this year and overall it looks great.  Only problem is that we have two arch rows of mini trees that are not lighting up fully.  By "not lighting up fully" I am implying that instead of a single tree coming "all on", only a portion of the lights on a given tree are lighting up.

There are 16 x 3-foot trees and then 32 x 2-foot trees.  We've been using them in this orientation for years.
 Those are all hooked up to a F16V2 that appears to have the channel counts set properly. That F16V2 is hooked up to one of six FPP's that also appears to have the channels setup properly.  The 2-foot trees take up the first eight outputs on the F16V2 and I have set one universe per output, starting at universe 98, 510 pixels per output / universe, so 98 through 105 for the 2-foot trees.  Each 2-foot tree has 25 pixels, so there are 100 pixels per output and 300 channels.  The 3-foot trees take up the second eight outputs on the F16V2 and I have set one universe per output, starting at universe 106, 510 pixels per output / universe, so 106 through 113 for the 3-foot trees.  Each 3-foot tree has 50 pixels, so there are 100 pixels per output and 300 channels.

Most of my effects in my main musical sequences are applied to model groups, either the whole display or all the 2-foot trees, or all the 3-foot trees.  I thought maybe that had something to do with it so I decided to break it down to basics this morning.  I wrote a sequence that is packaged and attached.  It applies a simple on effect to each of the 48 trees, for a couple of seconds, red, then green, then blue, then white, then a single strand effect.  When I run this sequence on the FPP, I get the same thing I am seeing in my musical effects.  Only a portion of the lights on each of the trees come on... some trees don't even come on at all.

What else... oh, if I go into FPP Test Mode and turn on all the channels for that controller in RGB test mode, the trees light up fine.  If I go into FPP Test Mode and tell it to turn on channels, let's say, 49000 to 50000, the first several 2-foot mini trees light up as they are supposed to.

If anybody has any time to look at this, I'd appreciate it, but I know we're all busy setting up our displays.  Even with the partially lit mini trees, the rest of the display is looking really amazing.  I have never packaged up anything and submitted it before, so if there is something I am missing, let me know.

Thank you

So as I suspected, this was something that I was doing wrong.  I wasted probably 5-6 hours of time troubleshooting this only to find out that, in the FPP Channel Output, I had transposed two numbers for the starting channel number of the FIRST 2-foot tree which threw off all the channel numbers of the 2-foot trees and the 3-foot trees that come after them.  49741 isn't equal to 49471.  What made it difficult is that I think my eyes were seeing the first two numbers and the last number were correct and completely overlooking the 3rd and 4th numbers.  Once they were fixed in the FPP Channel Output, all the mini trees started working.

Lesson Learned:  Never over-look stupid mistakes.

xLights and Pixel sequencing is a "Numbers Game."

There is little tolerance for error. I have 100% sympathy for your hours spent troubleshooting a hardware issue that wasn't a hardware issue. :(

Agreed, fixing numbers is always better than fixing hardware!

Spreadsheets are helpful. I rely on them so I dont screw up.

I have a spreadsheet. But with almost 300 universes, it's amazing how easy it was to overlook 2 little numbers and I would say that I am fairly ocd.  In this case, the fact that those 2 little numbers are such critical numbers also hurt (all 64 universes on that fpp are cloned after that first channel number and universe was entered).
