The assignment

This template contains three identical audio files, a few bars of alto sax playing a jazz waltz. How about turning this into a sax section with harmonies? It can be done quite quickly with Logic's Time and Pitch Machine. No extra players needed!

Follow these steps:

  1. On Track 2 select the Audio Region named altosax.2 and double-click to open the Sample Editor.

  2. In the Sample Editor open the Time and Pitch Machine [Factory > Time and Pitch Machine ...]. Now this looks interesting! For a start there's a picturesque graphical display with a ball that is moved with the mouse (Figure P16.1).

  3. Experiment! Mess about with it and use the Prelisten button to hear the results. This will give you a fair indication of what it's about.

  4. OK, you've had your fun! Let's get serious. The results we need are best obtained using the parameter menus . There are two columns , Original and Destination. We are going to transpose this file up a fourth. That's five semitones. So, enter 500 in the Destination Transpose parameter box. The Original should be set at 'Free.' Leave the Harmonic Correction set to 'off.' More on this shortly.

  5. Hold down the Prelisten button. You'll hear a speeded up version at a higher pitch. What do you think? Sounds a bit Mickey Mouse doesn't it? Well I don't mind. It'll not sound speeded up once processed and the altered tone sounds rather like that of a soprano saxophone . All the better in this case. Let's make a commitment. Press the Process and Paste button. The result? Well the original audio has altered a fair bit and the first note is now rather jagged looking and unpleasant to listen to. Apart from that, we can get away with it once it's played with the other saxophones.

  6. How to clean up that entrance ? There are various ways. Making a fade in [Functions > Fade In] is easy and does the trick (Figures P16.2 and P16.3). Adjust the Settings [Functions > Settings] until it's right. Alternatively use the Fade tool and create a curved fade in in the Arrange window (Figure P16.4).

  7. In the Arrange window, on Track 3 select the Audio Region named altosax.3 and double-click to open the Sample Editor.

  8. Open the Time and Pitch Machine, and this time set a Transpose parameter of 700. That's a fifth lower. This time turn the Harmonic Correction 'on.' Press the Prelisten button. It sounds rather like a baritone sax to me, which is fine. Press the Process and Paste button.

  9. Now play all three tracks together. Instant sax section!

  10. Save Song compare with project16/16.1.

NOTE

In the Time and Pitch Machine, transposition is measured in 1/100 semitone units ( cents ). In other words, one semitone is entered in the Transpose parameter box as 100. Raising pitch by a tone (two semitones) is therefore entered as 200 and so forth.
