record at half speed, slice just before each transient, move the the END of the transients to the left so they are about half the size, scoot em all over so the beginnings of the transients are lined up with the 16th beat. then crossfade the little bit you left behind the transient into the note that comes before it so you dont lose any pick attack but the next note blends with the previous.
(not sure if im using the word "transient" in the right context cus I usually hear it referred to drums, but IDK wtf to call the note haha)
