Event Type Structure
Note Events
Num
MIDI note number (note #). The range is from C-2 (note #: 0) to G8 (note #: 127).
Middle C is note # 60. It’s known as C3 in MIDI terminology.
On some keyboards/synth modules (notably those made by Korg and Roland), the note
range is C-1 (#0) to G9 (#127). In these cases middle C is called C4.
In the Preferences > Display Preferences page, you can reference the display to the
description that is most frequently used by your devices (Display middle C as…).
Val
Velocity of a note from 1 to 127. The zero value (0) carries the note off message, and
cannot be used here.
Length/Info
Length of the note. Although MIDI can only transfer note on or note off messages, Logic
actually stores the position and length of all notes, which makes them easier to access
musically. The note off message is generated automatically during playback.
Mapped Instrument Notes
If the edited MIDI Region is played through a mapped instrument, the defined names
of the individual notes appear in the Status line. For the sake of clarity, there is a small
note symbol to the left of each name.
