See, that's not music. No one in the real world thinks about "adding two notes" that way. It's not meaningful. Those numbers are just names. They don't have units. It's like asking "what does Bill + Fred equal?" Adding 12 to a MIDI note number gives you the number of the note one octave up, so 48 is C in the bass clef, 50 is D in the bass clef, and 98 is the highest D on a piano. However, there is no mathematical relationship between those notes. > I wanna calculate by half step also quartertones. > Ie: 48.5 + 50 = 98.25 Well, 98.5. > It means: c semi-sharp + d = ? MIDI can't do that. It doesn't support quartertones or non-integer note numbers. Some keyboards have non-standard extensions using pitch bend or sysex messages to do it, but it's not standardized. LilyPond can print music with quartertones, but it won't be in the MIDI files it produces. -- Tim Roberts, [email protected] Providenza & Boekelheide, Inc. _______________________________________________ lilypond-user mailing list [email protected] https://lists.gnu.org/mailman/listinfo/lilypond-user
