Chapter 32 Transposition With the Chord and Transposition Tracks 693
Analyzing MIDI Regions
You can use the Analyze button in the Chord track to analyze the chords in a MIDI
region. Select the desired MIDI region (preferably one containing complete chords) and
click the Analyze button in the Chord track header. The MIDI region will be analyzed,
with the resulting chords appearing in the Chord track. This also works for several
subsequent regions. Alternatively, you can drag the desired regions onto the Chord
track.
Note: Keep in mind that the chords in the Chord track are events, which affect the
playback transposition of MIDI events and Apple Loops. Make sure that you only use
the Chord track if you’re serious; once you use it, it always affects your composition. As
an example: When you analyze your project, then copy a region without copying the
chord track events. You should not use it if you only want to display the chords in your
project; in which case, you should use the Marker track or the Score Editor text chord
symbols.
Working in the Change Display Only Mode
You might come across situations where there are incorrect or missing chords in the
Chord track. As an example: You record a MIDI region, select it, and use the Chord
track’s Analyze button. Normally this should work fine, as the analysis algorithm is
rather intelligent and knows all about harmonics. If the result of the analysis process is
not as expected—and doesn’t comply with your recording—Logic Express provides
you with an easy solution: The Chord track’s Change Display Only mode. If you activate
this mode by clicking the Change Display Only option in the Chord track, you will be
able to adjust the chords to match what you’re actually hearing (the transposition
events in the Transposition track are adapted accordingly). All changes applied to
chords in the Chord track (while the Change Display Only mode is active) will have no
result on the playback of the corresponding MIDI regions—these changes will only
adapt the chords displayed in the Chord track to match the chords played in the MIDI
region.
The Change Display Only mode does not work with Apple Loops used on audio tracks.
For further information, see the Chord track description in the Apple Loops chapter on
page 645.
