When I click on a note in the pianoroll, I hear one note. I would like to hear ALL the notes at that vertical position by holding down apple-button (or so) while clicking. 1. click on a note: I hear one note, 2. apple-click: I hear ALL the notes at that vertical position. (The harmonies I am editing). "No rewinding, No setting play-offs, No markers, none of that. With apple-click I would hear the result of my edit to harmonies without constant play-rewind, play-rewind, every time... The song doesn't have to move, I move my cursor instead. Much faster, more intuitive and simple. In the arrange window there could be some similar function, holding down the cursor at a position, I hear the notes playing in that track. Control-click I hear the notes in all tracks at that vertical position. The song doesn't have to move, better I move my cursor instead to different locations with the speed of ligth. That's my logic wish #1.
