TRANSPOSING AUDIO AND MIDI
TOGETHER
When using the Transpose command
(Figure 81-15), you can of course select both audio
and MIDI tracks together to transpose them in one
operation. Just be sure to check both the MIDI and
audio check boxes as shown in Figure 81-15.
TEMPORARILY DISABLING PITCH
MODIFICATIONS
Any modifications you make to the pitch of audio
in the Pitch Layer of an audio track can be
temporarily disabled using the techniques
described below. When you disable pitch
modification in this way, all pitch edits are fully
preserved, and you can re-enable them at any time:
When pitch edits are disabled, you cannot edit the
track pitch layer information.
When pitch automation is bypassed using the ‘P’
button, the data is still processed in real-time so
that you can immediately hear the results when you
unbypass. In this case, the bypassed pitch
automation takes up just as much computer
processing resources as when it is unbypassed
(playing).
When pitch automation is bypassed via the Don’t
Pitch Shift soundbite setting, the pitch data is
completely ignored, therefore conserving your
computer’s processing resources.
CONVERTING AUDIO PITCH TO MIDI DATA
Pitch segments (Figure 81-2) can be copied and
pasted into MIDI tracks, essentially allowing you
to convert the pitch information in the audio into
MIDI data. This powerful feature can be used for a
wide variety of applications. For example, you
could layer a vocal part with MIDI parts, or sing a
melody and then convert it to MIDI data for
further development. The possibilities are endless.
The accuracy of the MIDI transcription is entirely
dependent on the accuracy with which the pitch
segments represent the notes in the audio. The
more accurately the pitch segments represent the
actual audio, the more accurate the MIDI
transcription.
Preparing for MIDI pitch transcription
Pitch segments are copied and pasted as is, so if you
have made any modifications to the pitch segments
— or changes to the pitch curve that are reflected
by the pitch segments — the changes will be
carried over into the MIDI track.
For best results, try these preparations on the pitch
segments before you copy and paste them:
■ Quantize pitch (Audio menu> Pitch and Stretch
> Quantize Pitch) to ensure that each note is
centered on its root pitch.
■ Make sure there is a one-to-one correspondence
between each pitch segment and each note that you
hear in the audio.
■ Review the timing of the pitch segments —
where they start and end — to accurately reflect the
full duration of each note.
These preparations will help a lot, but it is
important that you realize that the resulting MIDI
notes will not match the pitch segments exactly. See
“What you see is not what you’ll necessarily get”
below.
To do this Do this
To temporarily disable all
pitch modifications in the
entire track
Click the ‘P’ button at the bot-
tom of the track’s pitch ruler in
the Sequence Editor. You can
also use DP’s Option/Alt-click
and Command/Ctrl-click
shortcuts. Or choose Pitch
from the track settings menu.
To temporarily disable a spe-
cific soundbite’s pitch modifi-
cations
In the Sound File Info window,
set the soundbite’s Transpose
attribute to Don’t Pitch Shift.
