Transposing Percussion
You may be wondering why we did not transpose the percussion tracks.
As mentioned earlier, in General MIDI each note in the percussion
channel is mapped to a particular percussion instrument: a snare, a kick
drum, a cymbal, a triangle, and so on. Transposing the percussion tracks
will not change the pitch of each note but rather will change the
instrument used to play each note! This is not usually the desired effect,
so in general you would not use the Transpose command on percussion
tracks.
On the other hand, when a track contains events for only one percussion
instrument (that is, all the notes are the same pitch), you can change the
instrument by transposing the track. For example:
4. Click OK.
Pro Audio raises all the notes in the selected tracks by seven half-
steps (for example, C is raised to G, D is raised to A, and so on). The
Transpose dialog box also has an option for transposing by diatonic
steps; see “Transposing” on page 6-9 for more information.
To undo your transposition, choose
Edit-Undo
, or press Ctrl-Z.
If you want to transpose to a lower key, do the same thing, except
enter a negative number in the Transpose dialog’s Amount box. For
example, to lower the pitch of the song by a fifth, enter -7.
Note that you do not have to transpose entire tracks at one time; when
you learn more about selecting smaller sections of music, you will be
able to transpose individual clips, or parts of clips.
1. With the song playing, solo the Triangle track (track 7).
2. To hear the triangle more clearly, click in the Triangle track's Vel+
column and enter 127. This increases the velocities of the
triangle notes, which increases their notes’ volume.
3. Press Enter.
4. Select the Triangle track by clicking on its track number.
5. Choose
Edit-Transpose
to open the Transpose dialog box.
6. In the Amount box, enter -25.
7. Click OK.
The triangle sound is replaced with the sound of a cow bell.
