I don't know why this happens but with every sound set I get (But, not any of the sound sets from the MCLW forum) something always doesn't work, like with Travis's P42 sound set. The compressor doesn't work.
And in the Midwest locomotive works case the 710 set I have aliased to all of my SD70Macs and Ace's works fine... until I put 2+ on a train, when that happens the 2, 3, etc engine is the sounds the engine was aliased to before plays.
The FDL 16 works fine but, when I use 2 or more engines the horn is like 1/4 as loud is it should.
One weird thing is that the EMD645 set works perfect.
I tried many things like the "sound sliders" is MSTS - I played with those but it didn't work. Is there only a certain "DirectX" version it works on???
