Selecting Notes in a Chord
Another use for Select/Split Notes is to select only the upper or lower notes in a chord. Many times you may only want to affect the upper or lower notes in a chord—for example, to increase velocities or transpose pitches.
To select only the bass notes in a chord:
1. Do one of the following:

With the Grabber or Selector tool, select the range of MIDI notes that contains the notes.

To affect all the MIDI notes on a track, click in the track with the Selector tool, so that it contains a flashing edit cursor.
2. Choose Event > Event Operations > Select/Split Notes.
3. Select the Bottom option and leave the number of notes set to 1.
4. Click Apply.

In order for notes to be considered a chord, their start times must be within thirty-two ppq ticks of each other.
