Some others and myself are currently working on the Amtrak California fleet for MSTS. I happen to be working with the sounds. Since you seem to be very skilled in what BIN has to offer, I came to you.
Upon the door commands you excecute, would it be possible to have it play a certain loop when they open? The Amtrak California cars have a certain door chime for when they are open. As heard in this video: . When the chimes go faster, that indicates the doors are closing.
I would just like to know if this is possible, so I dont waste my time re-recording these sounds.
