I am running the sequence using FPP.
I save the xLights sequence file on the Mac. Then I upload the file into the Pi using FPP file upload, in FPPs File Maintenance tab. In FPP, I created a playlist which includes that sequence and I schedule the playlist. The playlist plays as scheduled. And like I said using FPP's test, I can set all 600 channels to what ever color I wish, run the test chases, etc. Of course I can also play the sequence in the test section of FPP. I just wanted to learn how to do a play list and schedule in FPP. FF
PP seems to be working fine.
BTW these are the lights I have connected to my PiCap. I donpt think they are the problems as I can drive them in FPP test mode.https://www.youtube.com/watch?v=1BAeLA_-gQE
I am almost certain the issue lays with the way I have defined the channels in xLights or in FPP.
The video I used to help be set my PiCap up does not cover this as the gentleman only has some 73 pixels -219 channels. Again I believe my troubles are due to me wanting to address more than 512 (or 510 not sure) channels with my set up.
One more thing there is a strange behavior. I set up a slow leaping arch chase in xLights. The chase goes from one string to the other - starts on channel 1 goes to channel 600 than back to channel 1. As the chase moves up the second string, it "stops" 3/2 of the way up (up to channel 512 my guess) but instead of the chase bouncing back immediate there is a slight delay as if it was "trying" to drive channels 512 to 600 and 600 back down to 1. So the chase goes out for a few seconds then it resumes is way back down the second string and down the first string.
