http://www.sibeliusblog.com/tips/numpad-3-0-for-iphone-supports-all-six-sibelius-keypad-layouts/

Now supports all 6 keypad layouts of Sibelius. As of the last version, it also allows you to rotate it 180 degrees, so you can keep it connected to your laptop without the cord getting in the way.

Also, it obviously wouldn't point this out on the Sibelius Blog, but it supports the Finale Simple Entry keypad layout as well.

AWESOME!  Can't believe I missed this app.  Thanks for the sharing this info.

Holy Crap! That app is totally amazing!

As is your rhyme scheme, sir.
