Hi Koda:

Most Technics instruments also comes with a reference manual. In it you will find other information that the owners manual doesn't cover. Thumb through the pages and see if you come across information regarding what other Technics models are compatible. The ones listed will be the software I would look into getting.

I have a PR900, and it is compatible with the the KN3000 software with a few other PR models. I also have a PR804, which is compatible with some PR's and the KN6000, KN6500 and KN7000.

You may not find much software for the PR54, but you may find the software for a compatible model that will work.

Hope this helps some...

Anthony
