Dynamic Constants
Dynamic or volume of notes (also known as MIDI velocity) is represented as in the MIDI specification using integers from 0 (silent) to 127 (loudest). That’s a total of 128 volume settings.
The music library defines the following dynamic constants:
FFF = 120
FORTISSIMO = 100
FF = 100
FORTE = 85
F = 85
MEZZO_FORTE = 70
MF = 70
MEZZO_PIANO = 60
MP = 60
P = 50
PIANISSIMO = 25
PP = 25
PPP = 10
SILENT = 0
