I have a few presets setup for 432 LED’s however I want to use the same presets for shorter lengths, i.e. 216 LED’s. Is their an easy way to convert them to work with the shorter lengths or do I need to rebuild them manually?

TYIA.

Kind of depends on the preset.  
If you’re doing something that involves the length of the strip to calculate grouping or such things, that would need rework.  
Some effects will have timing relative to the length of the segment.

Easiest from my POV would be open the segment(s) of the preset and reassign them a new length of 216. You could save them under a new name so it’s possible to have both available.

Just remove “stop” and “start” entries in “seg” array.

Would I remove them or change them to the right amount of LED’s?  
i.e. if it says start 0 and stop 108, I would change the 108 to 54?

And change the number of LED’s in the config?
