Well… It’s me again. This time I discovered it when I was writing an electric bass melody using three Minisampler plugins. It would be much more convenient to have the ability to display MIDI notes from another track in the background. For example, when I write some melodies on track 3, I need to counterpoint the melody of track 1, and I need to show the position of the MIDI notes of track 1 (or the shadow of the MIDI note position) on the track I am currently writing (track 3), but it is only displayed and cannot be edited. Each track in the MIDI editor can display MIDI shadows of other assigned tracks, which is necessary for some melodic work. Hope you’ll think about it, thanks!
Here are the examples I get them from other application:
