S4 Revolution (Original) Scroller incorrectly defines First Color as Last Color.
Gel Strings manufactured by ETC or made according to the S4R Original Manual,
will unexpectedly go to last color on string when DMX Scroller Channel @ 0.
Workaround -> change the gel string order in Eos Software Fixture Library,
OR Reassemble Color Scroller Cartridge so that the last color End of String (Trailer)
is attached to the Spool with the Spring Tension Label:
*Note: This was tested to be the same in MCC v3.0.2, v3.x.x, v2.0.0 and v1.0.10, and SCC v2.0.0, v1.0.10.
** Note: the DMX Values for the Original Gel String Frame Ranges in the current v3 Eos Fixture Library aren't exactly correct,
so when you step thru the different color frames, the scroller starts ending in not complete colors.
*** Note: S4 Revolution Wybron Scollers were manufactured correctly, and the Wybron manual was written correctly
to also have customers build the gel strings correctly to match the DMX channel profile inside the MCC Software.
