only works for 1 track so far, BUT....
you can now double-click musical event windows in the project window to
open the piano roll. The event window's placement is highlighted.

NOW WHEN YOU CREATE A NOTE IN THE PIANO ROLL it is bound to that event
window. NOW YOU CAN MOVE EVENT WINDOWS AROUND TO MOVE MUSICAL DATA
