Traditional Throttle Mode
Traditional throttle mode is how sound decoders of the past would "traditionally" operate, where the chuff intensity was one constant volume, or the prime mover notch is related directly to the speed. E.G. every (n) speed steps (of 128 speed steps) is a different notch, so the faster you go the higher the notch you will be in.
See the video below for a demonstration of Traditional Throttle Mode:
Configuration Options
Traditional throttle mode can be selected though and can be selected using Audio_Assist® menu 4.1. Both WOWSteam and WOWDiesel support Traditional Throttle Mode.
(WOWDiesel ONLY): The speed setpoints that the prime mover changes notches are controlled by CV165 through CV172 - where CV165 controls when the locomotive goes into Notch 1 and CV172 controls what speed step the locomotive goes into Notch 8.
(WOWSteam ONLY): To adjust the volume of the Chuff while in Traditional Throttle Mode, you need to change the volume level for the sound type "Chuff." This can be done easily through Audio Assist®. Note that making this change to the Chuff volume type will affect the maximum volume that the Chuff can reach when in Prototype Throttle Mode.
Other Traditional Throttle Mode Features
When you select Traditional Throttle Mode, the momentum values are set to the "Switching Momentum" values stored in the decoder as part of the Momentum Modes feature. The Switching Momentum values are typically low momentum values which disregard realism in favor of a "snappy" and "slot-car-like" operating experience which closely ties the speed of the locomotive to the speed on your handheld throttle. While it is still possible to slow down your locomotive using the Train Brake, it is not a requirement with Traditional Throttle Mode. That said, you can use the Momentum Modes feature to switch back to Mainline Momentum in case you only want to have the notching or chuff intensity be constant but the momentum be realistic.
