I took my 2-6-0 to the club to program on decoder pro, There really wasn't anything to change other than sound levels and address as I remember it. I printed out the Soundtraxx CV listing and looked for brake squeal and alternate whstle sounds but was unsuccessful. Even saying all that I still think it is a great deal and I look forward to what they bring out next.
I am looking seriously at the RF-16 A/A units for operations at the club. I could put a sound decoder into one of them and put train phones on both and they will be good to go.
