Wait, you can actually do a really neat trill with arpeggios set for chords, I never thought of that! [No Worries reference.] Yes, I have done this "by ear", and I should really say « by ear » because it's not accurate at all.
Heavy credit [is that a thing] to @Sohta_kun, whose music I have remixed. Yes, I know the second part of No Worries CharkeRemixed is completely different...idk why I did that I love chiffer lead btw
