About Changing Values and Timecode Entries

Soundtrack Pro includes several types of value entry methods. Most of them have features that can make changing the values or timecode fields easy to do.

Using Value Sliders

There are two methods used to enter general numeric values:

  • Traditional sliders with separate numeric entry fields

    Figure. Value slider displaying separate slider and numeric entry field.
  • Value sliders that combine the slider with the numeric entry field. Value sliders allow you to enter a specific number in the value field or to drag in the value field to set a value. When using the value sliders, you can use a modifier key to make normal, small, or large value adjustments. Dragging in the middle area (where the number is) works the same as an ordinary slider; dragging to the right increases the value and dragging to the left decreases the value. Additionally, you can click the right or left arrow to change the value one step at a time. You can also double-click the number itself and type a new number to enter a specific number in the value field.

To change values in normal increments
Do one of the following:
  • Drag left or right in the value field.

  • Click the left arrow to decrease a value, or click the right arrow to increase a value.

  • If you have a three-button mouse with a scrollwheel, click in the value field and use the scrollwheel on the mouse.

To change values in fine increments
Do one of the following:
  • Option-drag in the value field.

  • Option-click the left arrow to decrease a value, or Option-click the right arrow to increase a value.

  • If you have a mouse with a scrollwheel, Option-scroll in the value field.

To change values in coarse increments
Do one of the following:
  • Shift-drag in the value field.

  • Shift-click the left arrow to decrease a value, or Shift-click the right arrow to increase a value.

  • If you have a mouse with a scrollwheel, Shift-scroll in the value field.

When a value slider or value field is active (highlighted), press Tab to move to the next field.

Using Timecode Value Sliders

Soundtrack Pro uses timecode value sliders for timecode entry fields. In addition to being able to enter timecode values directly, you are able to scrub the timecode value by dragging.

If you place the pointer over a segment of the timecode, small arrows appear above and below that segment.

Figure. Timecode scrubber.

You can drag up or to the right to increase the value in that segment (values in segments to the left also increment if your dragging causes the selected segment to roll over). Dragging to the left or down decreases the value. You can hold down the Option key to make the value changes slower or the Shift key to make them faster.

Alternatively, you can click the up and down arrows on each side of the timecode value or press the keyboard’s Up Arrow and Down Arrow keys to increase or decrease the timecode value.

Figure. Timecode scrubber displaying caret.

You can control which segment is affected by the up and down arrows by selecting a segment so that a caret (^) appears below the segment. You can also use the keyboard’s Left Arrow and Right Arrow keys to select other segments.

Scrubbing Audio

You can scrub a multitrack project in the Timeline or scrub an audio file project in the File Editor. Scrubbing the project lets you hear the audio at the playhead position as you drag the playhead, so you can find a particular sound or event in the audio file.

You can scrub audio using either the Scrub tool or the playhead. For information about scrubbing, see Scrubbing Audio Files.

Scrubbing Video

In projects containing a video file, the video scrubs in the Video tab in sync with the audio as you scrub in the Timeline or the File Editor tab.

As you drag audio clips, markers, envelope points, or other items in the Timeline or the File Editor tab, the video scrubs at the start point of the item being dragged. Dragging multiple items scrubs the video at the start point of the item under the pointer.

You can use the Multipoint Video HUD as a visual tool for precisely positioning sound effects and other audio clips in a video program. For more information, see Scrubbing and Spotting with the Multipoint Video HUD.

Controlling Playback with the Transport Controls

You use the transport controls to control playback of your project. The transport controls let you set the playhead to various points in time, start and stop playback, activate the cycle region, and start a recording session to record your own audio.

Figure. Transport controls.
  • Record button: Starts recording at the playhead position on the track or tracks you have enabled for recording. If no track is enabled, a new track is created when recording starts.
  • Play from Beginning button: Starts playback from the position of the last playback start. Playback begins immediately, whether the project is playing or is stopped when you click the button.
  • Go to Beginning button: Sets the playhead to the closest of the following items to the left of the playhead: the beginning of the last playback start, the beginning of the cycle region, or the beginning of the project.
  • Previous Frame button: Moves the playhead backward by one frame.
  • Play button: Starts playing back the project from the current playhead position. Clicking the Play button again stops playback at the current playhead position.
  • Next Frame button: Moves the playhead forward by one frame.
  • Go to End button: Sets the playhead to the closest of the following items to the right of the playhead: the end of the cycle region, the position of the last playback stop, or the end of the project.
  • Cycle button: If a cycle region is set, clicking the Cycle button toggles whether the cycle region is active or inactive. If no cycle region is set, clicking the Cycle button sets the project to repeat from the beginning when the playhead reaches the end of the project. For information on setting the cycle region, see Working with the Cycle Region.
  • MIDI Sync button: Synchronizes playback with incoming MIDI Clock and MIDI Timecode (MTC) signals.

Controlling Playback Using Keyboard Shortcuts

There are a number of keyboard shortcuts you can use to control playback of your project. To use keyboard shortcuts, the pointer cannot be in a text field.

  • Space bar: Plays back the project from the current playhead position. If the project is playing, pressing the Space bar stops project playback. This is equivalent to clicking the Play button.
  • Return: Sets the playhead to the closest of the following items to the left of the playhead: the beginning of the last playback start, the beginning of the cycle region, or the beginning of the project. This is equivalent to clicking the Go to Beginning button.
  • Shift–Return: Sets the playhead to the closest of the following items to the left of the playhead: the beginning of the last playback start, the beginning of the cycle region, or the beginning of the project, and starts playback if it is stopped. This is equivalent to clicking the Start from Beginning button.
  • Option–Right Arrow or Option–Left Arrow: Moves the playhead forward/backward by one gridline.
  • Right Arrow or Left Arrow: Moves the playhead forward/backward by the current nudge amount. For information on how to set the nudge amount, see Nudge Amount and Project Preferences.
