// See cache.h for implementation drums, but the sensitivity values are flashed to the
#define SAMPLE_CACHE_LENGTH 16 board so you can't adjust them without re-flash the
firmware. If you use the provided board, connect the
2 drums and ignore the adjustable resistors.
// The maximum value of a hit (not the minumum value to trigger a heavy hit) - MODE_ADJUSTABLE: Allows you to adjust the sensitivity
// To configure the light and heavy thresholds, do it in the game settings values with the potentiometer as you play, but only
