OK, i know what a N.H. is and a A.H., (natural and artificial harmonic.) But i was using the guitar pro scream aim fire by BFMV version#4, and is had the notation S.H. which I assume means S. Harmonic...since its were I would have thought a A.H. would have been, anyone have any insight???

From tuxguitar.com:
Semi harmonic

Semi harmonics are in fact harmonics that are not played in the “correct” manner, so you can hear both harmonic and original note. They are most commonly used as “pinched harmonics gone bad”, and are very often used by many guitar players.

In TuxGuitar tapped harmonics are specified exactly the same way as artificial, pinched or tapped harmonics, they just don’t sound the same.
