     INTRODUCTION
  ----------------------------------------------------------------------------
   This is the Sound Definition Langauge (SDL) file for a project that can be
   used for a typical diesel locomotive. Supported
   sound effects include bell, dynamic brakes, air brake system,
   and coupler crash.

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

 Changes:
 1) disabled fans with FEATURE_DISABLE bit3 due to high noise distortion 6/9/2013
 
 Objectives:
     1) Use 4 channels (voices) avoiding previous version
        interruptions.
    2) Assign large 44KHz 16bit sound samples for best
        audio results
    3) optional startup sounds disable when F0 is on
    4) Feature disable CV169 is HEX values to disable features like HEP mode:
        bit0 disable HEP diesel ARTICULATED steam
        bit1 disable hard automatic braking
        bit2 disable startup sounds
        bit3 disable Fans
        bit4 disable toots on direction change    
        bit5 disable grade crossing random play
        bit6 disable bell    
        bit7 fuel prime once for Gen1 diesels OR
             multiple start warning bells Gen2
    6) F21-F28 Select Notch 1-8

(C) General Notes

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 F6 and F7, if you want your engine to sound
like it is working harder. Manual mode offers full control of the notch setting using F6 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 standing
- 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
- Additional user-defined sounds on F14 and F15

This sound project has been assembled from Digitrax-supplied sound clips as well as new sounds from custom recordings.
Additional custom 16bit 44KHz files were used to edit individual sound fragments (WAV files for each file handle).
It will be a copyrighted project on acceptance by Digitrax.
Thanks are due to A.J. Ireland for their prior work in developing sound projects.

** Switching speed is enabled by setting CV 54 to 1 with back EMF or 3 without back EMF

For CV155=01 ["Semi_automatic Notching"],  the Prime mover lowest Notch setting is set by
 the throttle speed setting. F6 (ON) can increase the Notch and F7 (ON) will decrease the
 Prime mover to the minimum notch set by current throttle setting.

The sound volume is controlled by Master Volume CV58 as well as any individual sound
volume CVs.  The Default for CV58 is 5 but can be set 0-15 from a Throttle or the sim-
ulated throttle in SoundLoader.  Individual sound volume CVs can be set 0-64.


Problems and exceptions:
 NOTCH RATE (CV132)
  Default is CV132=127 but that bunches the notches at the lower portion
  of the throttle range.  72-127 or higher is OK when your motor takes very little current.
  A value of 71 will spread the notches across the whole range, but may leave your
  engine moving too fast. It should run at scale speeds and notch.
