So, last night i attached 4 of my 5m WS2811 strips to my megatree and wanted to take them for a test run with my P12s and LSP. After some fantastic help from Matt, I had LSP talking to the P12s and could run some macros on the the strip lights. However, i do have a few clitches to work through and hence the request fro some more help. 1) I could only get the strip on the megatree to light up if i deleted all the other controllers I had setup. When I clicked the output button, I got an error message telling me there was an output config error but once all the other controllers were deleted, it worked. - So I am guessing that maybe one of the other controller setups is conflicting (although everything looked to be ok). - Or, as Matt suggested, that as I had a DMX universe setup (where i want to use dumb elements from last years display using LOR boards and AVD's DMX boards), I might have to have the LOR dongle plugged into the computer (even though the LOR boards weren't connected to the system at the time). Does anyone know if the dongle has to be connected to the pc to allow the output to work and stop the error message occuring or shouldn't it matter.? We also had to setup the P12s to use unicast or the lights wouldn't work. I thought multicast over local area network was the usual setting but it didn't work when we tried that. 2) My strings light up with the wrong colours (i.e I choose red but it comes out green etc). Do I go into the "string effects" page of the P12s and choose one of the effects to rearrange the RGB sequence (i.e RGB to GBR) until I get the colours out the right way, or should i change this in the controller setup in LSP? 3) When I ran the macro effects on the strings through LSP, the effects didn't run smoothly. So for eample, the vertigo macro was very jerky and jumpy and a colour slider effect didn't flow smoothly along the length of the strips but just lit up big sections in a jumpy fashion so I couldn't do any smooth-ish sweeping effects etc. The computer I was using is one of the new (and pretty fast) Macbook pros but I was running Windows in Paralells (Windows otherwise seems to run pretty quick in Paralells and LSP generates the macros quite fast as well so wasn't thinking that it should be a PC processing issue). Is there something in the LSP or P12s setup that might be causing this? Sorry in advance for the multiple, long winded questions ???
