Having particles like made in Rousseau's or Kassia's videos would be amazing! They don't really have streaklets. It really just fades into like gas. The difference I see from the SeeMusic ones and the ones made by the YouTubers I mentioned above.. is that when a note is pressed in those youtube videos, it looks like it evaporates into gassy particles. I see the difference as in those videos 1. They evaporate very quickly 2. They stay straight. 1. You can see in the photo where exactly Rousseau video particles vanish. In SeeMusic, even with Lifetime equal to 0.1 (the lowest) You can still see the particles at the top of the screen. So that's the first difference - when the particles become gone. 2. You can see that the particles stay relatively straight and up over here. In SeeMusic, even with Turbulence equal to 0 (the lowest) You can see that the particles spread out and go out like a triangle, instead of straight like the previous photo showed. So that's the second difference - the main direction of the particles. This software.... is.... amazing! It made me reduce a normally hundreds of dollar spend to few bucks max. It's mindblowing because everything can be done here. This addition would make it no different than spending hundreds. Thank you!
