If you have an iPad, check out: http://symphonypro.net.

The app allows you to create and edit sheet music. There's a built in keyboard and a real-time recording feature. If you have a Core MIDI compatible device, you connect it to your iPad and input notes in real time from that as well.

I can see you're already swamped, but I'd love to get some feedback. Our app is called Symphony Pro (http://www.symphonypro.net/). It's the premier app for creating and editing sheet music on the iPad.
