Selecting and Editing Events
Editing MIDI Events and Continuous Controllers (CC)
and makes the adjustment by altering the individual events. A value of 200 percent, for example,
stretches the selection to twice its original length, while a value of 50 percent shrinks the selection to
half its original length.
Process > Fit to Time stretches or shrinks the selection so that it ends at a specific time, expressed
in either measure:beat:tick (MBT) or hours:minutes:seconds:frames (SMPTE) format. This
command gives you a choice of modifying the events or modifying the underlying tempo. This is
useful when you want a portion of a project to have an exact length. The start time of the selection
does not change, but the end time is altered as necessary to fit the required time interval.
Both of these commands offer the option to stretch audio clips along with the MIDI information.
Sometimes you don’t want to adjust the speed of your audio.
Here are some examples:
• If your project contains background music and a voice-over, you might want to change the tempo
of the background music without altering the voice-over
• If you’re trying to modify the speed of some MIDI tracks to match a sampled drum groove, you
want to leave the audio unchanged
• If your audio consists solely of sound effects, you most likely do not want to adjust them
Audio can be stretched or condensed up to a factor of 4 (e.g., it can be shrunk to as little as 25
percent of its original length, or expanded to as much as 400 percent of its original length).
You can also use the Process > Length command to alter only the start times or the durations of
notes. For example, changing the durations of notes to 50 percent of their original length can create
a staccato effect.
To Stretch or Shrink Using Percentages
1. Select the events you want to change.
2. Choose Process > Length to display the Length dialog box.
Figure 86. The Length dialog
3. Choose to change the Start Times and/or Durations of selected notes by checking the boxes.
4. If you want to stretch selected audio clips, check the Stretch Audio box. When this check box is
enabled, the following two options become available:
• Type. Choose the type of audio data you're stretching. Choose options based on the source
material: single voice or instrument versus a group of instruments (ensemble or polyphonic),
