In case you're interested in using your laptops QWERTY keys for playing MIDI notes, here's a little utility I wrote that allows you to do that. A nice feature is that you can have any application in the forground while using it. You can download it from http://www.lasi.org/MidiKeyHook.zip. Let me know if you find it useful. I find it useful to be able to enter notes without using the mouse and in realtime, with no MIDI keyboard around.
