Settings
Logic Pro includes a real-time tuning system, for use with the included software instruments. You
can configure the tuning system in the Tuning settings.
When Show Advanced Tools is selected in Advanced preferences, the following are available:
•
Software Instrument Pitch: 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: Equal Tempered: Disables any tuning, and uses an equal
tempered scale.
•
Software Instrument Scale: User: Allows you to detune (move away) each semitone in steps.
Drag vertically in each semitone box until you reach the value you want, or double-click in a
box and enter a value. Click the Reset button to reset all of your tuning adjustments to their
default values.
•
Software Instrument Scale: Hermode Tuning (HMT): Because all tuning requirements can’t be
satisfied simultaneously with any one Hermode Tuning setting, this setting allows you to set
different Hermode Tuning modes and degrees of effect.
When Advanced Editing is selected in Advanced preferences, the following are available:
•
Software Instrument 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.
•
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.
