>>>>> WARNING!!! Independent mid-play volume change of NoteBlocks worked in Scratch 2 but is broken in Scratch 3 – unfortunately, once a note starts, you can't change its volume (but it still works for sounds) <<<<< I came across this question on the forums a couple of days ago: http://scratch.mit.edu/discuss/topic/50742/ The question is this: when you have several sounds or notes playing simultaneously, how to stop just one? I realised that clones provide a solution, so here's a little demo... Having each sound and note played by a clone means you can stop an individual one by deleting the clone that's playing it. You can also control the volume for each independently while it's playing. Can't pause a sound, though... :(
