I've recently purchased a Digitrax PR4 and downloaded the software to allow me to load sound projects into my locos. I've successfully done that using sound files available on the Digitrax site. But, I've got a Bauchmann 0-6-0 that I've converted to DCC using Digitrax decoders, and a Mantua 0-6-0T on my layout. I don't like the sound alternatives for these small locos that came with the Digitrax decoder, nor the Mantua sounds. Does anyone know where I can find sound files that can be loaded to these locos?
