NO, only Lokprogrammer works to load sounds in to Loksound decoders.
The basic rule is: If you can get JMRI to connect to your hardware, you can use JMRI to program any decoder (OK, 95%) .

Start with something simple, like Digitrax 123 or Bachmann "DCC on board". You need to crawl before you can fly.
Ask a local friend, or the local NMRA group for help. Likely they will be eager to show you how to do anything.
