Besides the now fixed 64 bit looping sounds on the AP Class 40, another comment I read somewhere was that the sounds were perhaps a bit too quiet compared to the real thing. I recently acquired the 40145 and that too had much quieter sounds than, say, a 37, from outside too. I never really saw them in real life, but from what I've seen on YT videos, the real thing does sound a little louder. What are others opinions? Does anyone else notice a difference? Is there a way to "crank up th volume" in the sound files somewhere?
