- Click the MIDI tool
. Select the region whose
playback data you want to affect. Double-click the highlighted
area. The MIDI tool window
appears. Drag through the graph region above the notes to select all of
them, or SHIFT-click (or drag-enclose) individual note handles if you
want only certain notes to be affected.
- Choose MIDI tool > Key Velocities; then choose MIDI tool > Scale. The
Scale dialog box appears.
- Specify the degree of crescendo or decrescendo
by filling in the From and To text boxes. There are two buttons
at the bottom of this text box: Absolute, and Percent of Original. If
Absolute is checked, the numbers you enter are MIDI velocity values, which
can be from 0 (silent) to 127 (very loud). If you choose Percent of Original,
you type percentage values (for example, you might want to create a crescendo
that increases from 100% to 150% of the current volume). This last option
is useful for preserving the existing dynamic balance of the music while
still achieving a smooth increase in volume.
- Click OK (or press RETURN).
You can also create a MIDI-based playback crescendo by increasing
the MIDI Volume controller. See Volume
and Continuous
data. To automate this task for hairpin crescendos, see Smart
Playback.
