I checked in both XY and SV, the low health beep actually plays 4 times and not 3. Should probably be changed

Edu, is it within your power level to use a config to control the loop point in the midi itself? I think your current version is totally fine and should be merged, but a config like B_NUM_LOW_HEALTH_BEEPS that just controls how many time the existing one loops would be the better / less invasive version
