Exploring Editing Controller Information in a Software Instrument Region
Many keyboards include controls for pitch bend and modulation as well as a port to connect a sustain pedal. The Pitch Bend and Modulation controls are usually wheels that are placed on the far left of the keyboard controls. These controls are used to add expression and character to your music, and you can view and edit the movements of these controls in the Track Editor.The editing controller information in the Track Editor looks like a series of lines with control points. You can click-drag control points up or down to change their value, or move them left and right to change when they occur. To add a new control point, click the line, or Cmd-click an empty area to draw a new line. To delete a point, click the control point to select it, and then press the Delete key.In the next two exercises, you'll look at the advanced editing controller information for sustain and pitch bend in the Track Editor.
Viewing Sustain in the Track Editor
A sustain pedal has only two options: it's either on (pressed) or off (not pressed). When you play a note and press the pedal, the note will sustain after you stop pressing the note. If you press a note when the sustain pedal is not pressed, the note will end when you release the note on the keyboard. You can play more than one note while holding the sustain pedal.Let's take a look at the sustain that was recorded with the strings track in the song Highway Bound.
If you look at the Sustain controller information, you will see a line near the bottom that is marked 0 and another line near the top that is marked 1. The lower line (0) represents the pedal in the off position, and the upper line (1) represents the pedal in the on position. If the pedal is held down for most of the song, as it was in this recording, you will see a series of blocks that represent a note or group of notes that are played and sustain until they end. When a new note or group of notes is played while the pedal is held down (on position), a new block forms. If the pedal is released, you will see a space between the blocks with a straight horizontal line at the off (0) position line.Editing Sustain Controller Movement
Now that you've seen the Sustain controller movement, you can actually edit it to make a note sustain longer or shorter. Your goal in this exercise is to extend the sustain for the last note in the first half of the song.
Viewing Pitch Bend Controls
Now let's take a look at the Pitch Bend controls. The Pitch Bend controller on a keyboard allows you to bend a note up one step or down one step from the original note. You can see an example of the Pitch Bend controls in the project 9-5 Pitch Bend.
The center line is the actual note that is played. The section above the center line illustrates that the pitch of the original note was bent one step (one note) higher. The section below the center line illustrates that the pitch of the original note was bent one step (one note) lower.The next time you record a Software Instrument region and use Pitch Bend or Sustain controls in your recording, you will know how to use these controls in the Track Editor.
