(such as in a passenger car), a setting of 1 will enable the effect.
Note: When activating F9, the generator sound will play according to the
settings in CV 202.
Generator Volume
CV 132 controls the generator volume and may be set to any value from 0 to
255. The default is 25.
Generator Probability
CV 202 allows you to set the frequency of the generator sound effect,
enabling you to re‑create prototypical scenarios appropriate to your railcars.
CV 202 may be programmed with any value from 0 to 255. A value of
0 will cause the generator to never turn on, suitable for non‑refrigerator
cars. Conversely, a value of 255 will cause the generator to run constantly,
suitable for passenger cars where generators run non‑stop for climate control
purposes. Or, select a value somewhere in‑between to re‑create the sound of
a generator in a refrigerator car turning on and off according to the heat of the
day.
Clickety-Clack Control
The clickety‑clack sound effect can be adjusted to match the type of car and
the type of rail. The following CVs control the clickety‑clack sound effect:
CV 112, Sound Configuration 1
CV 116, Moving Sound Scalar
CV 131, Clickety‑Clack Volume
Clickety‑Clack Sound Configuration
Bits 1 and 2 in CV 112 allow you to set the number of axles per truck and
trucks per car to synchronize the clickety‑clack rate for your model.
Use bit 1 to set the number of axles per truck. For two axles per truck, keep
bit 1 at its default setting of 0. For three axles per truck, set bit 1 to 1.
Bit 2 controls the number of trucks per car. For two trucks per car, keep bit 2
at its default setting of 0. For one truck per car, set bit 2 to 1.
Examples: If you have a bobber caboose, which only has one truck with two
axles, you will set CV 112 to 4 (bit 1 = 0 + bit 2 = 4).
For a sleeper car that has two trucks with three axles, set CV 112 to 2
(bit 1 = 2 + bit 2 = 0). To keep your passengers comfortable, you may want
to also enable the generator to always be on, so add a value of 1 to enable
bit 1, which will give you a total CV 112 value of 3.
Moving Sound Scalar
To further fine‑tune the clickety‑clack rate (as well as flat spots), use CV 116
to set the proportion between the speed step and the scale speed in feet per
second (ft/s). This CV can be programmed with any value from 0 to 255 to
