Diesel Version 5:Rotate Feature

The Rotate feature allows for easy changing of the horn or bell while on the mainline. Simply play a horn, then press the rotate function (F9 by default) and the decoder will announce the new horn. If you want to change the bell play a bell, then press the Rotate function, a snippet of the new bell will play and that is now the new bell.
Since there are so many bells and horns on the decoder, if you find yourself rotating past the desired sound, simply change the direction of the locomotive, and the rotate feature will rotate the opposite way through the sound selection. The sounds are listed in alphabetical order.
