Hi Anthony,

Yes it has NX sound and GM2 and can load SMF 0/1, SMF with lyrics and DOC*1 files.

The biggest 2 features I've found that the PR54 does not have that my KN6000 had (besides only being 64 note polyphonic) are the Performance Pads and the 20 Custom Style Memory Locations for Storing Custom Styles but it does have the 3 Custom Style Memory locations used when a song is loaded with a Custom Style. This is also used to load and play the many styles I have on disks from the KN series. They all play and sound great on the PR54. It has a quick load feature so you just press and hold the Custom Memory button and it reads the disk in the drive with the styles on it. The nice part about this feature is that it only loads the style and not all the other setting that are loaded when you press the Disk-Load-Load buttons.

I'm sure there may be others but these are the ones I miss.

It also incluses the USB port and the same Song Manager and Recorder software that come with the KN7000.

Oh, it doesn't have the voice Harmonizer either which I never used.

Best Regards
