Title: Whitcomb sound
Post by: SoCalBobS on December 06, 2017, 06:31:23 PM
Got my Whitcomb last week.  Got a question about the sound: all seems to be in working order, except maybe one thing.  Is there an acceleration factor for the engine noise? Mine produces an idle noise, and an in motion noise, but the in motion noise stays at the same rpm regardless of the speed.

Otherwise itís just great, just curious why the engine noise doesnít reflect speed, like steam chuffs for the steam locos.

If you're using DCC and have a controller that can change CVs, try increasing CV 116.

Aside from the sound files, the CV list appears to be identical to my Heisler's sound module, and CV 116 is for exhaust control/chuff rate.

Thanks Flare, I gave CV116 a try with different values, didnít hear a change.  Iíll keep checking on forums.

I tried all kinds of things and the sound didn't change on mine, either.
That, and the muffled quality of the sound due to the heavy and thick body on the Whitcomb, makes for so-so sound (especially compared to my ten-wheelers, which sound great).
