Tuning project settings in Logic Pro for iPad
Logic Pro for iPad includes a real-time tuning system for use with the included software instruments. You can change the tuning system in the Tuning project settings.
Software instrument pitch
Tune field: Determines the global tuning of all software instruments. Detuning is in ± cent (1/100 of a semitone) steps. The default value of 0 cents refers to the concert pitch A (440 Hz).
Software Instrument Scale pop-up menu: Choose from two different tuning scales:
Equal Tempered: Equal tempered is the most commonly used scale in classical music and Western music today.
Hermode Tuning (HMT): A microtonal tuning system that adjusts 3rd, 5th, and 7th intervals to make them sound harmonically richer.
Hermode Type pop-up menu: Only displayed when you choose Hermode Tuning (HMT) from the Software Instrument Scale pop-up menu.
Pop/Jazz (3/5/7-All): 3rds, 5ths, and 7ths are changed in this mode. It’s great for pop and jazz styles, especially when using sustained chords. It’s less suitable for polyphonic music because the detuning of the natural 7th is significant. This mode should always be used with a Depth of 90% or 100% because other values render the natural 7th acoustically ineffective.
Classic (3/5-All): This mode provides a broad and regular tuning of pure 3rds and 5ths. In cases of conflict, the degree of purity is temporarily reduced. This mode can be used for all types of music. The value of the Depth parameter indicates the degree of the 3rd and 5th purity. A setting of 100% determines maximum purity. A 10% value is the lowest purity setting. Off sets the tuning to an equal tempered scale.
Baroque (3/5-Adaptive): This mode tunes pure 3rds and 5ths (with changing characteristics). In tonal music, with a clear harmonic center, the middle chords are tuned very purely, whereas more distant chords are tuned with less purity. If the harmonic center becomes unclear, all chords are tuned with equal purity. As with the other mode parameters, a Depth value of 100% determines the highest purity, and a value of 10%, the lowest purity.
Depth field: Only displayed when you choose Hermode Tuning (HMT) from the Software Instrument Scale pop-up menu. It allows you to set the degrees of 3rd and 5th purity between 0% and 100%.
