situation. Define the (sound) speed in CV #375 (often used
for idle sound while coasting).
= 0: does NOT mean F0, but rather that NO key is assigned
for coasting.
= 1 ... 28: One of the function keys F1 … F28 for “Coasting“
Coasting-Step
(or Notching)
Motor speed (sound) to be activated with coasting key (as
per CV #374), independent of driving situation.
= 0: Idle sound (typical coasting situations)
= 1 … 10: Sound speed (Diesel engines typically have 5 to
10 notches, which can be activated with the coasting key.
The volume for “background” sounds (boiling, brake squealing etc.), function sounds, random
sounds and switch input sounds can be set within the sound selection proccedures (see the
“CV #300 procedures” above).
More convenient however is the direct volume adjustment by CV’s (especially when no
sound selection is necessary, which is often the case). Of course, not all sounds listed below
are part of every sound project. Changing sound CV values of sound files that are not part of
the relevant sound project have no effect.
Background sounds - Volume adjustments:
Thyristor sound volume (ELECTRIC engine)
Start whistle/horn volume
Blow-off volume (STEAM engine)
Electric motor volume (ELECTRIC engine)
Switch gear volume (ELECTRIC engine)
Second Thyristor volume (ELECTRIC engine)
Pantograph up volume (ELECTRIC engine)
Pantograph down volume (ELECTRIC engine)
Pantograph stop (down) (ELECTRIC engine)
Turbocharger volume (DIESEL engine)
Dynamic brake volume (ELECTRIC engine)
Note: The CV ahead of the CV’s listed (#573, 575 etc.) contain the sound sample numbers to be played.
Function sounds - Volume adjustments:
Sound volume operated with function key F0
= 0: full volume, original sound sample volume (same as 255)
= 1 .. 254: reduced volume 1 - 99,5 %
= 255: full volume

Volume for function sound F2

#674, #677…#698 = volume for sounds on F20, F21…F28.
Note: The in-between CV’s above (#570, 572, #513, 515, 516, 518 etc.) hold information for the relevant
sound samples (sample numbers, loop parameters etc.), which can also be modified if needed, usually with
the CV #300 procedures.
Switch input sounds - Volume adjustments:
Volume setting for the sound activated by switch input S1.
= 0: full volume, original sample volume (same as 255)
= 1 .. 254: reduced volume 1 - 99,5 %
= 255: full volume
Volume setting for the sound activated with switch input S2
Volume setting for the sound activated with switch input S3
NOTE: If a decoder comes with a potentiometer for volume control (mostly on large-scale
decoders), the pot meter should NOT be fully opened if full volume is not really desired (Loss of
sound quality if pot meter is fully open and at the same time the volume is heavily reduced by
CV’s!).
