neblix, great mini-tutorial! Thanks for taking your time.
Ah, perfect, that was one of my main questions! So, if I'm writing sixteenth and eighth notes the notes will all fit exactly in a certain number of squares, and then if I need to write some triplets, I just change the grid so that tuplets fit to it, right? ..and when I change the grid back to sixteenth notes, the triplets I wrote will look out of place in the grid, like in the middle of two squares, right?
Me neither... although I think he got some of the durations wrong, but the idea is there.
One last couple of questions: those yellow vertical lines at the bottom, what are they? and, in a piano roll, velocity is the same or similar to tempo/bpm in standard notation?, those two passages would be in 127bpm?
