Default MIDI editting while looping
 

Hi,
How could I edit just one midi note in the Edit Window while my song is being played in a loop mode?

When I select a part of the song in order to play a loop and then i open the midi Editor window, all midi notes are selected, so when I try to move one note, all notes move in the same way. If i select just the desired note I loose my loop. I cant find a solution to this.

I would appreciate any help
Regards
