Here is one example:
Let's say you have a recording of Elvis Presley singing "Love Me Tende"r on your computer in MP3 Format.
With the kit you can convert this Elvis MP3 song so that it plays in your KN7000 or 2600, That's cool enough, especially if you do disk jockey type gigs.
But wait, that's only the beginning. If you save this Elvis MP3(now called an Audio File on the keyboard) and place that song in position 1 of an Audio folder, you can Audio Syncro and save as a Technics File.
With this, you load the Elvis Audio file, and hit the Audio Syncro button, and you now can play your keyboard along with Elvis singing in the background. Is that cool or what? By saving the whole performance as a Technics File, you can recall yourself playing the 7000 with Elvis singing instantly at a push of a button. You can add pics via picture load, and edit like any other Technics file. Of course you can't edit the original Audio(mp3) file, unless you record the Technics/Audio file to a computer where with some decent software you can futher edit both yourself playing the keyboard and Elvis singing.
Maybe you'll want to sing along with Elvis and save it back to your 7000...but then maybe you really wouldn't want to do that.

Anyway with a little imagination and the correct software, the possiblites are many.
