Sdn144ps sound programing

[darticus]

Don't like the factory scuff setting sound. How can I change the sound to have more scuffing hiss like real steam. Working with the Digitrax Zephyr extra. Can anyone tell me where the scuff settings are and how to set them. Do I have to remove other locos from the tracks and is this done on the programing track? Thanks Ron

You need to tweak these CV's to get the sound you want. If this still doesn't do it you will have to buy a PR2 or PR3 to load a new sound file into the decoder that fits what you want. By scuff do you mean Chuffing sound? There should have been a cam piece that came with your decoder for a steam install. Take all other locomotives off the track when you are programming a locomotive to make sure you don't mess up the other locomotive's CV's as well.

Thanks, I'm looking for a better steam sound as the factory steam sound I'm using doesn't have enough hiss. Maybe I have to change CV's. Don't know if I can get it to change enough. Ron

OK if changeing the CV's doesn't work you will have to get the PR2 or 3. The PR3 costs 70 dollars and is a USB interface to your computer.
