Wczytałem bibliotekę, wybrałem przykład ColorPalette, efekty zamieniłem na case'y przypisane do kodów 0-9, w loop wywołuję sprawdzanie kodów, jak jest inny niż 0 , a często jest przy wywołaniu efektu co 100ms, to ignoruję, jak jest któryś z tych 0-9 to zmieniam efekt.
Faktycznie czasami odczytuje 0 przy ustawieniu na 10FPS, a przy 50ms (20FPS) to już same 0, coś zaczyna działać od 60ms.
Ledów mam 24 w ringu, jak miałbym to zrobić tylko na AVR to dodałbym Attiny13 by czytał mi kody IR NEC i przez soft serial wysyłał na UART sprzętowy Atmega, ma bufor, odczyta w przerwaniach, to 1 bajt, zadziała na 100%.
Jak masz więcej led to i 100ms może czkać.
Za to ESP8266, w sumie ten sam kod tylko zmienione dwa piny dla IR i LED, bez problemu śmiga w ustawieniu na 10ms, i na 1ms, bez zająknięcia, sterować można tym wtedy również przez WIFI, z drugiego końca świata (jak masz zewnętrzne IP i umiesz przekierować porty na routerze).
Tak że możesz trochę powalczyć, albo zrobić to na tańszej płytce jak Wemos MINI.
Ewentualnie są takie ledy z SPI, jest sprzętowy w Atmega328p, to wtedy może działać 10x szybciej, a na pewno jest tu opcja użycia przerwań zamiast blokować na kilkaset us /ms uC by nadawać banglując pinem.

// This example shows several ways to set up and use 'palettes' of colors
// with FastLED.
//
// These compact palettes provide an easy way to re-colorize your
// animation on the fly, quickly, easily, and with low overhead.
//
// USING palettes is MUCH simpler in practice than in theory, so first just
// run this sketch, and watch the pretty lights as you then read through
// the code. Although this sketch has eight (or more) different color schemes,
// the entire sketch compiles down to about 6.5K on AVR.
//
// FastLED provides a few pre-configured color palettes, and makes it
// extremely easy to make up your own color schemes with palettes.
//
// Some notes on the more abstract 'theory and practice' of
// FastLED compact palettes are at the bottom of this file.

// Additional notes on FastLED compact palettes:
//
// Normally, in computer graphics, the palette (or "color lookup table")
// has 256 entries, each containing a specific 24-bit RGB color. You can then
// index into the color palette using a simple 8-bit (one byte) value.
// A 256-entry color palette takes up 768 bytes of RAM, which on Arduino
// is quite possibly "too many" bytes.
//
// FastLED does offer traditional 256-element palettes, for setups that
// can afford the 768-byte cost in RAM.
//
// However, FastLED also offers a compact alternative. FastLED offers
// palettes that store 16 distinct entries, but can be accessed AS IF
// they actually have 256 entries; this is accomplished by interpolating
// between the 16 explicit entries to create fifteen intermediate palette
// entries between each pair.
//
// So for example, if you set the first two explicit entries of a compact
// palette to Green (0,255,0) and Blue (0,0,255), and then retrieved
// the first sixteen entries from the virtual palette (of 256), you'd get
// Green, followed by a smooth gradient from green-to-blue, and then Blue.
