Description
#290
Thyristor sound,
“slow” pitch increase
for
ELECTRIC engines
0 - 255
Sound pitch for speed defined in CV #292.
#291
Thyristor sound,
maximum pitch
for
ELECTRIC engines
0 - 255
Sound pitch at top speed.
#292
Thyristor
low speed
for
ELECTRIC engines
0 - 255
Speed for sound pitch per CV #290.
#293
Thyristor control,
Volume at steady
speed
for
ELECTRIC engines
0 - 255
Thyristor sound volume at steady speed (no ac-
celeration or deceleration in progress).
#294
Thyristor control,
Volume during
acceleration
for
ELECTRIC engines
0 - 255
Volume during accelerations
#295
Thyristor control,
Volume during
deceleration
for
ELECTRIC engines
0 - 255
Volume during heavier decelerations (braking)
#357
Thyristor control,
Lowering the volume
at higher speeds
for ELECTRIC
engines
0 - 255
Internal speed step at which the thyristor sound
volume should be reduced. The volume stays at
this reduced level while braking.
By changing CV #158 Bit 6 = 1, the volume will be
raised while braking, nonetheless.
#358
Thyristor control,
Volume reduction
curve at higher
speeds
for ELECTRIC
engines
0 - 255
Defines a curve as to how the thyristor sound
should be lowered at the speed step defined in
CV #357.
= 0: no reduction.
= 10: reduced by about 3% per speed step.
= 255: aborts the sound when the speed step
defined in CV #357 is reached.
Thyristor control
0 - 255
0

0 - 255
0
Time in tenths of a second (0

back; useful when the first switching step is al-
ready part of the sound sample “idle -> F1”.
= 0: Switchgear is heard immediately at depar-
ture.
