Sound Projects

There is 1 Sound Project for this Locomotive
RS3 8 bit project by John McMasters, added on May 9, 2013

CV155    Notching mode should(must) be =1: 0 = Auto, 1 = Semi auto, 2 = Manual [1]   


This is a functional tested version of a project using individual sound recordings for each prime mover notch setting. These
prime mover sounds can be played in three modes determined by CV155: automatic, semi-automatic and manual notching. In auto
mode, the prime mover notch is determined by the current speed setting, and is adjustable using CV132. In semi-auto mode,
the same is true but it is possible to "throttle up" to higher notches using F11 and F7, if you want your engine to sound
like it is working harder. Manual mode offers full control of the notch setting using F11 and F7, so you can throttle down
to idle and turn on dynamic braking while coasting downgrade.

Other features available in this project include:
- Automatic grade crossing horn sequence with bell
- Optional highball and backup horn signals while stopped
- Dynamic brakes at speed, or handbrake while stopped
- Automatic coupler sounds when changing direction at low speeds
- Automatic brake squeal sounds when decelerating to a stop
- Manual brake squeal on F9 and moving

This sound project has been assembled from Digitrax-supplied sound clips as well as new sounds from custom recordings.
