Apple Logic Pro 9 - Manual (Page 1225)

Software Instrument Pitch Settings
• Tune slider: Determines the global tuning of all software instruments. The default is
concert pitch A (440 Hz). Detuning is in cent (1/100th of a semitone) steps.
Software Instrument Scale Settings
• Software Instrument Scale buttons: Select the appropriate button in the Software
Instrument Scale section to activate alternate tuning scales. The selected tuning scale
is saved with the project when saved, and reloaded the next time the project is opened.
• Equal Tempered: Disables any tuning, and uses an equal tempered scale.
• Fixed: Activates a number of fixed tuning scales and keys. Fixed Tuning mode tunes
musical keys (to different degrees) for scaled tuning systems, and delivers a key
signature character. When playing mostly white keys (in the Pure setting, and with
C as the root key), C major is the main focus, and tuning is scaled to that chord. An
A major chord that is played immediately after a C major (and is therefore subject
to C major scaled tuning) is affected somewhat by the scaled tuning effect, but will
not sound completely tempered. If you normally play polyphonic music, this mode
(when using the Pure setting) will sound most pleasing to your ears. The Fixed Tuning
scales are ideal for a number of Baroque and Medieval instruments and styles of
music.
• User: Allows you to detune (move away) each semitone in steps.
• Hermode Tuning (HMT): As all tuning requirements cannot be satisfied simultaneously
with any one Hermode Tuning setting, allows you to set different Hermode Tuning
modes and degrees of effect.
• Fixed: Type pop-up menu: Offers the most important historic tuning scales, as well as
a few others.
• Fixed: Root Key pop-up menu: Allows you to choose a global key (C-B) for the chosen
scale. This provides an easy way to reference the chosen scale to any root note.
• User: Semitone boxes: Detune each semitone in steps, by dragging vertically in each
semitone box until you reach the value you want. Alternately, you can double-click in
each semitone box, and type in a value. Press Return or click in another box to exit text
entry mode.
• User: Reset button: Resets all of your tuning adjustments to their default values.
• User: Upper slider: Determines the deviation (from the equal tempered scale) in the
treble end of the sound. The higher the value, the farther down the low notes are tuned.
A setting of 0 results in an equal tempered scale tuning.
• User: Stretch Lower slider: Determines the deviation (from the equal tempered scale)
in the bass end of the sound. The higher the value, the further down the low notes are
tuned. A setting of 0 results in an equal tempered scale tuning.
