"Import" drum patterns?

[SonnyDaye]

Is it possible to "import" drum patterns, say from another keyboard or sound module (or even an old "drum machine") either via midi or usb? I'm looking for some simple Swing patterns (with no Bass Drum "bombs" thrown in).
Also, are there any patterns (Swing and also Bossa Nova) that have been posted anywhere that I could d/l and import into my Juno-Stage?
I tried creating my own via the editor/grid on-board, but I'm not satisfied with the results. I figure I need to import patterns that have been created by someone who actually knows what they are doing.
Thanks to anyone who can point me in the right direction to solve my problem!
