One of the more common uses for Transpose is
to change the key for your MIDI tracks. You can
define an Edit Group for MIDI tracks that you
want to transpose, making sure to exclude any
drum tracks from the group so they aren’t trans-
posed.
To transpose MIDI notes to another key:
1 If you will be transposing a group of tracks,
make sure to enable the Edit Group.
2 With the Selector or Grabber, select the range
of MIDI notes to be transposed.
3 Choose MIDI > Transpose.
4 Select the option for Transpose (From, To).
5 Set the “From” and “To” values, for example,
to C4 and E4 to transpose from C to E.
With either of the pitch fields selected, you can
play a note on your MIDI controller to automat-
ically enter it as the pitch value.
6 Click Apply.
It is also common to transpose MIDI tracks up or
down by an octave.
To transpose a MIDI track up by an octave:
1 With the Selector, double-click in the track to
select all of its notes.
2 Choose MIDI > Transpose.
3 Select the Transpose By option.
4 Enter a value of 12 semitones and then click
Apply.
Quantize
The Quantize command adjusts MIDI note loca-
tions and durations so that timing is improved,
or so that a particular rhythmic “feel” is
achieved. Quantize works by aligning notes to a
Quantize Grid, the size of which is defined in
the Quantize window by a standard note dura-
tion.
The Quantize command is not the same as the
Quantize Regions command (in the Edit menu).
The Quantize Regions command adjusts the
start point for a selected region, and its contents
are moved along with the region (with rhythmic
relationships remaining intact).
The Quantize command, on the other hand, af-
fects MIDI notes individually. Some notes may
be moved back in time, others forward; and,
some notes will be more drastically affected
than others.
The settings in the Quantize window are
saved with each session. To store your fa-
vorite settings as the default for use in future
sessions, save them as part of a session tem-
plate (see “Creating Custom Session Tem-
plates” on page 51).
