As I have a particular led layout divided into three physical segments , am I right if I just build a new led array to make a virtual strip and then change the code on draw function to use my virtual strip and after that just call a mapping function ?. Thank you
(I’m just only thinking at the moment , as there is heavy storm here and all power went off at home , so no computer , only tab and cell ., Not for long … .)
No matter how you have setup your leds, you need to give a pointer to ONE CRGB array to the Compositor object as it is currently done in line 44 of the ino file
Compositor myComposition(leds, NUM_LEDS);
when you call myComposition.draw() in the loop your led array is fully rendered and ready to be shown out through fastLED. In between those two steps you could use mapping functions, etc. if needed. Hope that helps.
Hope your storm is over soon 
thank you, im back now on the computer, i have VS working now , it was a missing component during installation (?),
i took the midi references out, and compiler gave an error
FastLEDCompositor.ino:http://www.youtube.com/watch?v=QE71RSuA8qs&t=10m20s: error: variable or field ‘changePalette’ declared void
:void changePalette(PaletteName pn)
FastLEDCompositor.ino:http://www.youtube.com/watch?v=QE71RSuA8qs&t=10m20s: error: ‘PaletteName’ was not declared in this scope
Error compiling project sources
but i couldn’t find the problem, should i force a pallet definition?
like PaletteName= PN_RAINBOW
PaletteName is defined in ParameterSet.h which should be included if you did not change anything else and therefore should be known.
As soon as I find some time I can try to do a blank install and maybe make a short tutorial video how to do it from scratch and by doing that also find out myself what might be issues with it.
I have to figure out how to put everything together in an Arduino library, I dont know yet how to to that.
I couldn’t find were it is included . I searched with vs. And found no place . Then I included it by brute force on the msin ino . But is not the right place …
i have confirmed that there is no include for parameterset , it is probably missing from the source code
the only include is on parameterset.cpp
but then it seams that is never called…
am i missing something ?
it should be included with Compositor.h…if you did not change anything in the code its weird that it gives those errors…I have to check it myself, hopefully today
