Take as reference the attached MSTS Route Editor picture. It shows a complex station track layout, featuring some couples of sound region markers. The markers looking in the direction of switches and double slips relate to switch/double slip sound, while the markers looking in the direction of standard track relate to default sound. Therefore when a train passes over the switch/double slip you hear the related sound. But there is a problem: if you lay out the couples of markers too near to the switch/double slip point of diverging ORTS does not interpret well the sound change, and selects the default sound and stays to it. MSTS instead interprets well the sound change even if the markers are quite near to the point of diverging. So sound region marker layouts of some existing MSTS routes do not work well under ORTS.
Does the problem still happen with version 1.4?
