In the Edit window on MIDI and Instrument tracks in Notes view, in MIDI Editor windows, and in the Score Editor, the Free Hand shape inserts a single MIDI note whose velocity is defined by the Default Note On Velocity setting. The pitch, location, and duration of the note are determined by where on the track you click with the mouse.When editing MIDI velocities or continuous controller data, the Free Hand shape draws freely according to the movement of the mouse. The shape is reproduced as a series of steps according to the Pencil Tool Resolution When Drawing Controller Data MIDI preference.In the Edit window on MIDI and Instrument tracks in Notes view, in MIDI Editor windows, and in the Score Editor, the Line shape inserts a series of MIDI notes on a single pitch whose velocities are defined by the Default Note On Velocity setting. The duration and spacing for the inserted notes are determined by the current Grid value and the Default Note Duration setting.When editing MIDI velocities or continuous controller data, the Line shape draws in a straight line from click to release. MIDI continuous controller values change in steps according to the Pencil Tool Resolution When Drawing Controller Data option in the MIDI Preferences page.In the Edit window on MIDI and Instrument tracks in Notes view, in MIDI Editor windows, and in the Score Editor, the Triangle shape inserts a series of MIDI notes on a single pitch whose velocities oscillate between the Default Note On Velocity setting and 127 according to a triangle pattern. The duration and spacing for the inserted notes are determined by the current Grid value and the Default Note Duration setting.When editing MIDI velocities or continuous controller data, the Triangle shape draws a triangular pattern that changes direction according to the current Grid value. MIDI controller values change in steps according to the Pencil Tool Resolution When Drawing Controller Data option in the MIDI Preferences page.In the Edit window on MIDI and Instrument tracks in Notes view, in MIDI Editor windows, and in the Score Editor, the Square shape inserts a series of MIDI notes on a single pitch whose velocities alternate between the Default Note On Velocity setting and 127. The duration and spacing for the inserted notes are determined by the current Grid value and the Default Note Duration setting.When editing MIDI velocities or continuous controller data, the Square shape draws a square pattern that repeats at a rate based on the current Grid value.In the Edit window on MIDI and Instrument tracks in Notes view, in MIDI Editor windows, and in the Score Editor, the Random shape inserts a series of MIDI notes on a single pitch whose velocities change randomly within the range between the Default Note On Velocity setting and 127. The duration and spacing for the inserted notes are determined by the current Grid value and the Default Note Duration setting.When editing MIDI velocities or continuous controller data, the Random shape draws a series of random values that change at a rate based on the current Grid value.
