Copying and pasting pitch segments
After making the preparations listed above, copy
and paste pitch segments as follows. This
procedure assumes that you want the resulting
MIDI notes to play in time with the original audio,
so you will be pasting the MIDI data at the location
where the first pitch segment begins:
1 Select the pitch segments with the Arrow tool
(lasso cursor).
2 Choose Copy from the Edit menu.
3 To paste the resulting MIDI notes so that they
play in time with the original audio, leave the pitch
segments selected and choose Set to Selection
Bounds from the Selection Information window’s
Set To menu as shown below in Figure 81-16.
Figure 81-16: Setting the selection to match the currently selected
pitch segments.
4 Click the name of the MIDI track you wish to
paste into to create a time range selection in the
destination track that matches the current
selection start time (which now matches the start
time of the first pitch segment you copied).
5 Choose Paste from the Edit menu.
What you see is not what you’ll necessarily get
When you copy pitch segments and paste them
into a MIDI track, the resulting MIDI notes will
likely not exactly match the original pitch
segments. This is because Digital Performer
interprets the pitch segments with respect to the
waveform to create a MIDI performance that
matches the audio as closely as possible.
To further refine the timing of the resulting MIDI
notes, try quantizing them. Best results are often
achieved by quantizing both attacks and releases of
the MIDI notes.
FORMANT-CORRECTED VS. STANDARD
PITCH SHIFTING
In the Sound File Information window
(Figure 37-22 on page 349), each soundbite can be
configured for either formant-corrected pitch
shifting or standard pitch shifting (Figure 37-23 on
page 350). This setting affects real-time pitch
automation. If you wish to preserve the original
character of the sound, such as for harmonizing or
pitch correction, use the (default) formant-
corrected setting. For special pitch effects,
experiment with standard pitch shifting. For
further information about these modes, see
“Soundbite preferences for transposing and time-
stretching” on page 349.
ZTX PROCESSING PREFERENCES
In Preferences > Audio Options (Figure 7-24 on
page 84), the Pitch and Time Stretch Options let you
adjust the quality and speed of the ZTX processing.
Try experimenting with different settings here for
best results. You can change the settings on the fly
at any time.
BACKGROUND PROCESSING
As soon as you OK the Transpose dialog, the
selected soundbites (or pieces of soundbites, for a
time-ruler selection) are replaced with new
soundbites, which are analyzed and processed in
the background as described in “Background
Processing” on page 899.
