A friend was over for ops so I cranked up the Proto BL2 with the RP EMD-567 ULT file. Ran the engne until it cycled through the generator startup. He immediately commented that it was the 'whoop' of a GE generator, and a late model one at that. I had no idea until now, but checking some videos, he was right. I wonder who put that file together, and how to get the correct sound in there?
