FastLED DemoReel for APA104 RGB+W

/*
 Mark Kriegsman's DemoReel 100 modified for APA104 RGB+W LEDs.
 This is the first humble attempt to use RGBW LEDs with FastLED.

 APA104 are 'improved' WS2812B, so this LED_TYPE can be chosen as well.
 The strip is set up with alternating Color and White LEDs.
 http://www.szledcolor.com.img.800cdn.com/upload/2015423162708_1.jpg
 To make things easier the White LEDs have also an 3 x 8 bit internal
 register and behave like normal color APA104, just with the difference
 that there are 768 brightness steps for the white LED.

 In order to address following them arrays were defined
 CRGB leds_Color[NUM_LEDS];
 CRGB leds_White[NUM_LEDS];
 To fill them with the right odd and even numbers Daniel Garcia
 contibuted this formula to allow the special FastLED functions.
 for(int i = 0; i < (NUM_LEDS/2); i++) { leds[i*2] = leds_Color[i]; leds[(i*2)+1] = leds_White[i]; }
 The function is executed in beginning of the loop.

 For optional plain access the arrays can be defined as
 uint8_t Array_Color[] = {0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100, 102, 104, 106, 108, 110, 112, 114, 116, 118, 120, 122, 124, 126, 128, 130, 132, 134, 136, 138, 140, 142};
 uint8_t Array_White[] = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47, 49, 51, 53, 55, 57, 59, 61, 63, 65, 67, 69, 71, 73, 75, 77, 79, 81, 83, 85, 87, 89, 91, 93, 95, 97, 99, 101, 103, 105, 107, 109, 111, 113, 115, 117, 119, 121, 123, 125, 127, 129, 131, 133, 135, 137, 139, 141, 143};

 For longer strips you find at the bottom of the sketch even and odd numbers from 0 .. 1000
