One of the great things about LokSound decoders is you can upload new sound files to them whenever you want. This can come in handy when the LokSound folks release a new sound package containing sounds from your favorite locomotive or a new selection of bells or horns, etc. Plus you can make modifications to the sound package itself with the new version 5 decoders. So let's take a look at the equipment you'll need as well as the process for uploading a sound project to a LokSound decoder.
Here's a link to the LokSound website where you can find sound packages:
