Same here, John. All decoders from Digitrains, sound files too. One loco; the DP1 has a Loksound because I couldn't get a decent file for a Zimo. Unless I start it at speed step 1, it won't start smoothly using the acc setting. CV2 is set at 1 and CV3 is at a high figure (can't remember exactly) and should be smoother, but that's another story.
