Hear notes that aren't playbacked when starting midway.
Yes that's a nice title, let me explain. I cannot explain it without an example, so I'll use an example.
In the images you can see an orchestral score... yes it's that score again. So, if I start the playback from where the horns start playing (ON Number 5) the horns will be heard. But if I start the playback EXACTLY a moment after the horns start (like in the moment shown in the second image) they won't be heard... so my idea is that: if you want to hear something in a specific time with all the instruments, but some instruments are already holding a note from before the moment you want to hear, then they should ALSO be played, because now they won't be heard.
