Edit Pitched Tracks
Enabling the Edit Pitched
Tracks option lets you transpose existing MIDI
notes on Pitched tracks up or down, either dia-
tonically or chromatically based on the key
change, or constrain pitches to the new key. For
more information on Pitched tracks, see
“Pitched Tracks” on page 702.
Transpose
When the Edit Pitched Tracks option
is enabled, lets you transpose existing MIDI
notes on Pitched tracks up or down, diatonically
or chromatically. For example, if the session is
in C major and you are adding a key change to D
minor, select Edit Pitched Tracks, Transpose,
Up, and Diatonically to transpose notes on
Pitched tracks up a whole step and then lower
the third, sixth, and seventh scale degrees by a
half step. The sequence C, D, E is transposed to
D, E, F (natural, rather than sharp as happens
when transposing chromatically).
When transposing diatonically, chromatic
notes are maintained when changing key. For
example, when changing key from C major to E
major, the note B-flat is transposed to D-natural.
This lets you maintain “blue-notes” when
changing keys and applying diatonic transposi-
tion.
Constrain Pitches To Key
When the Edit Pitched
Tracks option is enabled, lets you constrain
pitches to the notes of the new key. This means
that any diatonic pitches of the old key on
Pitched tracks that are not in the new key are in-
dividually transposed to the nearest diatonic
pitch of the new key. For example, when chang-
ing from C major to D major, the sequence C, D,
E, F, G changes to C-sharp, D, E, F-sharp, G.
Constraining pitches to key also constrains any
chromatic pitches to the new diatonic scale. For
example, when changing from C major to D ma-
jor, the sequence C, D, D-sharp, E changes to C-
sharp, D, D, E.
Pitched Tracks
Pitched tracks are MIDI or Instrument tracks
that can be affected by transpositions due to key
changes (including constrain to key). MIDI and
Instrument tracks are “pitched” by default.
However, if you have MIDI or Instrument tracks
assigned to drum machines or samplers, you do
not want those tracks to be affected by key
changes because of key mappings. You can dese-
lect the Pitched option for specific MIDI and In-
strument tracks so that they will not be affected
by key changes.
To select (or deselect) Pitched tracks:
