It ends up 4 notes because I hit the muted string (d) at the exact same time as the fretted string (a). So just applying more force so the pick moves twice as far/twice as fast for that note compared to the other notes. Like a double string rest stroke. So the muted string can't be heard over the fretted one and I'm keeping the rhythm straight 16s, no tuplet added! I'm not sure I like the up-stroke because 1) it ends up being such a big motion changing direction and doesn't feel super efficient (but that could be me just not being used to the motion). And 2) sometimes I'm coming down from a sweep the other direction right before that note with another string skip, so either way I would have to go through a string without changing direction. Hm, this one is interesting, a little bit fiddly but may have potential. This one is also interesting, I quite like it! Hybrid picking definitely adds some extra control compared to sweeping.
