I'm not sure which version this started in, but I noticed it in 3.4.2 (before that I used 3.2.3 without this problem). The synthesizer has changed how it acts. I use CC11 for single note dynamics, which I've done since SND first came out. In 3.2.3 (or earlier), I clicked the switch all sounds to non expressive button and saved the synthesizer settings as my default. When I created a score, the instruments in the mixer were of the non-expressive variety. Now when I create a score the instruments in the mixer are the expressive variety and do not play using CC11. I've tried using the set to non-expressive button but it doesn't remember that I pressed it. In fact the save as default button is grayed out. There should be no need to go into the synthesizer every time I create a score.
