Duration of
acceleration sound
Time in tenth of a second
Chuff sound
volume during full
acceleration
The volume of steam chuffs at maximum acceleration.
Threshold for decel-
eration sound
Steam chuffs are played back at less volume (or mut-
ed) signifying the reduced power requirement during
deceleration.
Duration of reduced
volume during
deceleration
After the speed has been reduced, the sound should
remain quieter for a specified time
Volume level during
deceleration
Defines the chuff volume during deceleration
(Default: 20 = pretty quiet but not muted).
The brake squeal should start when the speed drops
below the specified speed step.
Minimum driving
time w/o brake
squeal
Minimum driving time before brake squeal is played
back.
Thyristor:
Stepping effect
= 1: no stepping effect, continuous ascend
> 1: ascending scale according to the corresponding
speed step interval.

Electric motor,

Internal speed step at which the motor sound becomes
audible.

on speed
Volume increase dependent on speed.

sound,
Sound pitch
dependent on speed
Sound pitch increase dependent on speed.
For various sound sample mappings.
For “Incremental Programming” of sound CV’s
Number defines a brake key (Brake curve is defined in
CV #349)
Number defines a key for sound ON/OFF functions.
Function sound
ON/OFF key
Defines an ON/OFF key for sounds that play back with
function keys.
= 0: Function sound is always ON.
Defines a water blow-off key.
= 0 (to 10): minimum time setting of 1 sec.
= 11…255: longer “fade” times
Random generator
Z1
Minimum interval
Defines the shortest possible interval between two
consecutive pulses.
Random generator
Z1
Maximum interval
Defines the maximum time interval between two con-
secutive pulses
Random generator
Z1
Playback length
Times the random sound is repeated.
= 0: Sound is played back only once.
Random generator
Z2
Minimum interval

Playback length
Defines a key to raise the diesel sound
