@Lorpal it’s not the same thing. If you look at the chart @scorpiknox posted, you’ll see that when you play a C note the harmony man will add an E and a G (3rd and 5th) but when you play a D note the harmonizer will add an F and a B.
If you set the Diatonic algo for 3rd and 5th up, the C note harmony will be the same, but when you’ll play a D note the H90 will add an F and an A.
