Hello,

I've got an idea regarding the view of the notes. Until now you have the piano roll editor where you can see the notes you are playing. But it would be great if there was a window which can display the (recent and next) notes of each instrument that is playing (or if you're recording a song) in real-time in a musical score (alone or together with the piano roll so you have both options at the same time).
For example like: http://s74.photobucket.com/user/rossduc ... s.jpg.html or http://static1.squarespace.com/static/5 ... ore+Window.
(I don't mean midi-export/import or using the music or its notes in another program such as MuseScore)
This would be great for the future of LMMS.
Here's an example that shows what I mean: https://youtu.be/FilC5RUBXxo?t=53s
