Atero, you really should stop being such a nitpick. Reflectocube does have some sort of custom beat-detection for the cubesize. Slightly modified for range 0 to 1 gives you:
It's more like a lowpass derivative filter than a 'beat-detector' but it matches beats pretty nicely.
Just because it doesn't modify the behaviour of the "on beat" box doesn't mean it's not beat-detection.
I refuse to make a subwoofer preset for (c)rap music though
