Ok thanks for your help.  I wrote to Bachmann tech support to see if they could help.  I did find the file in JMRI decoder pro under the tcs folder, but Bachmann does nor recommend using the computer to change cv's....so I'll wait to see if tech support answers my email.  Appreciate all the info you passed. Thx

Thank you so much for the quick response.  Your advice is much appreciated and I will give it a try.

before I do although this is a sound value dcc from Bachmann this is not a tsunami decoder.  They used a TCS decoder with a dumbed down wow system.  It does not have the audio programming of the full tcs decoder.  So I would have to set the cv's as you suggest the usual way.  Would you know if the cv's are the same on this decoder?

I was able to find the extended CV's on this decoder on Bacmann's web site, but the CV's you listed are not there.  Are These standard CV's

Thanks in advance

I recently purchased a sound value EMD GP35 and would like to turn on the auto sounds for direction and grade crossing, but I am unable to find what cv's control these functions and what values to put in.  I have the full sheet of cv's for this engine, but it is still confusing as to what cv's to change.

The file for using JMRI decoder pro is not available for this engine and Bachmann only recommends the use of approved NMRA systems for changing cv's on their products.  Any help would be appreciated.
