You can mute individual notes in the Piano Roll Editor, letting you experiment with different note choices in a melody, or different chord voicings, for example.
Do one of the following:
Click one or more notes with the Mute tool.
Select the notes, then click one of the selected notes with the Mute tool.
Muted notes are shown without color.
The Select Muted Regions/Events key command is also available in the Piano Roll Editor. You can use it to select all muted notes in a MIDI region.
Click a key in the keyboard at the left of the Piano Roll Editor, then click one of the selected notes with the Mute tool.
This action mutes or unmutes all notes of the clicked pitch in the MIDI region, and is useful for muting the hi-hats in a MIDI region that is triggering an entire drum kit, for example. For information about assigning tools, see Assign tools.
