Regarding the Sync Strings Pro... (or maybe any Sync Library), in the GUI overview,
at the top of each Dimension, next to the Key Switch or controller assignment, is a small icon with what looks like 3 layered pieces of paper (if the layers were round, I'd take this to represent an old-school HD icon). Some of them are colored blue, some not. In my current project, none of them are colored in. Try as I might, I have not found an explanation for what these little icons represent, let alone the difference between highlighted/on or not.
Thanks in advance of any info.
