Where can I find piano chord midi files to compose with?

[dblock]

I can't play piano so I'm looking for some midi piano chords that I can switch around and manipulate to give me some song ideas.
Are there midi files that have piano chords that work somewhat like all these drum groove midi files where you can cut the chord patterns, edit, switch the order the chords are played in alter dynamics and basically make them my own for composing? I've been searching for a while.
Thanks

Would suggest looking at Band in a Box... This product allows you to enter chords by "name"... as C7, Dm, etc. and in a sequence timed to any meter. You can then export the rendition as MIDI... so you'll not only have chords, but a basically entire rhythm section if you like. It's a great sketch pad tool. I play piano, but I travel extensively so it's a nice tool to compose on when sitting in an airplane... don't need a MIDI keyboard to get ideas down.
