Using the Piano Roll Palette

Previous pageReturn to chapter overviewNext page

To edit the piano roll rectangles of notes rather than just view them, you need to use the Piano Roll Palette:

prcarrow To begin editing the as-performed locations and durations of notes:

B8Navigate to the Piano Roll Palette.
-- OR --
Type SHIFT + Y.

PianoRollPaletteMainButtons-7

Composer enables you to independently edit the notation of notes and the as-performed timing of the notes.
 

prcarrow To tell Composer whether you want to edit just the as-notated locations and durations of notes, or the as-performed locations and durations, or both:

B8Click the Edit Both As-Performed and As-Notated understanding_the_piano_1 button if you want the editing of note locations and durations to affect both the notation that you see and the performance of the notes that you hear.

-- OR --

Type "pn" or "np" for as-performed equals as-notated.

B8Click the Edit As-Notated Only understanding_the_piano_2 button if you want the editing of notes to effect only what you see in the score but not the actual performance of the notes.

-- OR --

Type "en" for edit notation.

B8Choose the Edit As-Performed Only understanding_the_piano_3 option if you want the editing of notes to effect only the timing of the notes as you hear them played back, without changing the way they are notated in the score.

-- OR --

Type "ep" for edit performance.

When you click one of the three Piano Roll Palette buttons to choose a combination of editing the notation and/or performance of notes, Composer will display the piano roll rectangles and notes differently, according to which option you choose:

B8If your editing affects the notation, then the notes are shown in normal black color. If your editing does not affect the notation, then the notes are de-emphasized with the gray color.
B8If your editing affects the performance, then the piano roll rectangles are filled with a bright yellow color. If your editing does not affect the performance, then the piano roll rectangles are de-emphasized with a white interior.

Once you have chosen one of the options for Edit Both As-Notated and As-Performed, Edit As-Notated Only, or Edit As-Performed Only, then you can edit notes in the following ways:

B8Move the attack (start location) of the note.
B8Move the release of the note, thus changing its duration.
B8Shift both the attack and release of the note at the same time, so that the duration of the note is preserved but the note starts at a different location.
B8Quantize ("snap") the as-performed attack and/or release of the note to its notation location or duration.

The following diagram shows what the Piano Roll Palette buttons look like, depending on which option you have chosen for Edit Both As-Notated and As-Performed, Edit As-Notated Only, or Edit As-Performed Only:

PianoRollPaletteDetailButtonsExplained

You can find out the purpose of each of the editing buttons in the palette by briefly holding the mouse over the button. Composer will display a short message explaining what that button does, and what the keyboard short-cut for the command is. You can also learn what the Piano Roll Notation buttons do by understanding the meanings of the small drawings on the button faces.

The graphics on the piano roll palette buttons follow a consistent convention, which is summarized in the following diagram:

    PianoRollButtonExplained-1

For example, the above button has the following effect on the selected note:

    PianoRollButtonExplained-1-score-example

Each of the four corners of the button may or may not have an arrow that points to the left or right. The two arrows on the top half of the button indicate the effect of the button on the notation of the note. The two arrows on the bottom half of the button indicate the effect of the button on the as-performed timing of the note. The direction of the arrow indicates whether the attack or release of the note is to be moved to the left or the right. In the above example, the button shifts the entire note, both its notation and its as-performed timing, to the left.

If the button only affects the notation of the note, and not its as-performed timing, then there are no arrows in the bottom half of the button face, and the piano roll icon in the button is displayed in a faded color. Also, the button may affect only the attack, not the release, in which case there is an arrow only on the left side of the button, not the right side. The following diagram illustrates these cases:

    PianoRollButtonExplained-2

For example, the above button has the following effect on the selected note:

    PianoRollButtonExplained-2-score-example

If the button only affects the as-performed timing of the note, and not the notation, then there are no arrows in the top half of the button face, and the quarter note icon in the button is displayed in a faded color. The button may affect only the release, not the attack, in which case there is an arrow only on the right side of the button, not the left. The following diagram illustrates these cases:

    PianoRollButtonExplained-3

For example, the above button has the following effect on the selected note when it is clicked several times:

    PianoRollButtonExplained-3-score-example
