quite a thorough discussion. A few self-centered comments:
I'm currently re-sequencing my entire show in Xlights. I made that choice because the program is object oriented. this gives me great flexibility to change any model as I wish; upgrade features, etc. . Also the program effects and speed are wonderful. I'm stuck on XL's!
A little background on my "import effects" feature use:
To make my 2014 show I converted my 2013 LSP files to Xlights xseq files (Lighting_Elf), then added new effects to the existing models. Worked great! It had some limitations: I couldn't edit the imported LSP effects. The problem I was trying to solve this year (When XL4.0 starting to come out) was that I needed to re-assign channel numbers to my controllers(models) to add new features. I had little choice but to start over because I couldn't "see" the convert effects in XL sequencer nor change the model channel assignments of the LSP models.
To re-sequnce is a slow process ; so when the good efforts of the XL developers made a conversion pathway for LSP files directly, I thought I'd convert the LSP files and then add additional features. And since the import feature mapped to XL models, I thought I could import, modify the model channel numbers for the new layout and therefore save a bunch of time. But everything has trade-offs!
From the discussion, it appears for large LSP files or sequences, the simple import feature may not be all that simple.
Anyway, I'd like to see the import effects feature work, even if it will not be practical for large LSP files. (BTW: I've got ~23,000 channels of RGB)
Thanks to all. Any advice is welcomed!
