+- when you click on a note in the piano roll, it plays the note, but not the correct panning
+- fix ctrl+mousewheel zooming in
+- if you press both controls at the same time, the piano roll gets stuck in selection mode
+- change my modifier code to use mainwindows modifier info
 - multiview button - show notes from every instrument in the current beat+bassline with different colors
 - undo/redo for piano roll
