I am aware of those, and will likely pick them up (although I read here, I think, that this expansion only includes about 25% of the midi patterns that come with EZ Keys). 

It’s still a substantial amount if you dig deep.

For example, I am thinking about this: http://www.prosonic-studios.com/Midi-Progressions-Details.aspx?lngCollectionID=76.

I tried a few of the download demos. Basically they are notation i.e. there is nobody playing them, there is no pedaling, no dynamics etc. For me, part of what I am paying for with EZ keys is the real pianist. The thing that you linked to is merely patterns. If you used them in a song it would sound like a quantized, step-sequenced borefest.

There are tons of midi files on the net. Midi is midi. The key is to find files with some symmetry so they will work. Chords have to be 4 (or more) notes and laid out so that the changes are on the measure or half-measure in order to do the transpositions. Many midi files don’t have pedaling, so you would have to add it. Hopefully you can find some with real people playing. The nice thing about the EZ Keys files is that they are already sliced up in phrases with pedaling intact.
