Carenando ATR72 Feathering Sound Question

I have recently purchased the Carenando ATR72-500 addon for FSX and also the TSS ATR six bladed sound set.

One thing I’ve immediately noticed is that the feathered prop sound is more or less the same as when advancing the condition levers to idle power. As soon as I move the lever from fuel cut off to feathered position the RPM sound is as if full idle instead of the quieter feathered sound like on the real aircraft. Has anyone else experienced this and is there anything that I should/shouldn’t be doing so to simulate the correct feathered sound initially when starting?

Thanks,

Richard.
