Sometimes you might want to temporarily mute particular clips or individual notes in a MIDI clip. To figure out what's unnecessary, unwanted or to add variations or a break. However you don't want to destroy anything you already have in the process.
In Live you can quickly do this by deactivating clips or notes. They still exist in the same spot, but are not audible. The command works like a switch and thus re-activates them when called a second time. You will only see the option that is not in play, meaning when the clip is deactivated, you will only see 'Activate Clip(s)' and vice versa.
To deactivate/activate a clip:
Right-click (Win) or Ctrl-click (Mac) on the clip and choose the command 'Deactivate Clip(s)' or 'Activate Clip(s)' from the context menu.
To deactivate/activate notes in a MIDI clip:
Double-click the desired MIDI clip, select the note(s) to mute, then right-click (Win) or Ctrl-click (Mac) to choose the command 'Deactivate Note(s)' or 'Activate Note(s)' respectively.
To deactivate/activate multiple clips or notes in a MIDI clip:
Use Ctrl (Win) or Cmd (Mac) or click and drag to select multiple clips or notes, then right- or Ctrl-click and choose the command. If you want to deactivate all notes of the same key (e.g. C3), right-click on the respective key in the piano roll and choose the command.
