Tempo
Tempo in bpm (beats per minute). Make sure you set the right length in bars, or the
correct original tempo will not be shown on the left!
Length (Samples)
Length in samples.
Length (SMPTE)
Length in SMPTE time.
Length (Bars)
Length in bars. If you have already adjusted the song tempo to the Region that you’re
about to edit, the original value will automatically be set correctly. If not, you need to
manually enter the original length here.
Transpose (Cent)
Transposition of the sound material in 1/100 semitone units (cents).
Free Transposition
You will see the Free pull-down menu next to the Transposition parameter.
This is the most common setting when using the Time Machine. It means that the
program performs “free” compression/expansion or transposition. In this situation, the
pitch and tempo of the audio material are completely independent of one another.
Classic (Correlated) Transposition
Switch the pull-down menu from Free to Classic. The Classic mode is for situations
where you want to transpose a selected Region, and also affect its tempo. This
produces an effect that you’re probably familiar with, as it simulates the sound of
changing tape speed. In this scenario, the pitch, sonic character, and playback speed all
change.
Audio Algorithms
Version 5 algorithm
This is the well-known algorithm of Logic 5 and earlier versions.
Any material
This is the most universal algorithm, which should be able to handle any kind of
material—it is the new default setting when using the Time Machine.
Using the Graphic Display
To the left of the Time Machine window, you can see a graphic representation of the
current settings. You can grab the ball within the graphic, and freely move it to adjust
the compression/expansion, and pitch shift. The further the ball deviates from the
center position, the harder the algorithm has to work, and the lower the expected
sound quality will be.
