I'm trying to add compressor sounds to the class 375 included with the Chatham mainline by creating a controlled loop which will play (Under the MOSL.proxyxml file) when the controller CompressorState is set to 1, although through testing I have found that the controller simply remains set to 0, even when the compressor is running. Any help would be appreciated from train sim devs, I have been trying to get it to work and none of the train sim dev documents have helped
