With the sound limitations in MSTS, it would be hard to re create every sound aspect that comes from a GEVO. Since I am a loco engineer, I recorded every notch from both inside and outside of the cab of a GEVO. When I tried it in MSTS, it kept crashing. I had a different set of sounds for inside and outside of the cab. I then tried it with someone elses sounds and it worked fine. So I think that it would be a big issue to get every sound.
