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
do not sound completely tempered. If you normally play polyphonic music, this mode
(when using the Pure setting) sounds 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.
• User:Stretch 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 farther down the low notes are
tuned. A setting of 0 results in an equal tempered scale tuning.
• User: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.
• Hermode Tuning:Type pop-up menu: Allows you to set different Hermode Tuning
modes.
• Classic (3/5-all): This mode provides a broad and regular tuning of pure 5ths and
3rds. 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 5th and 3rd 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.
• Pop/Jazz (3/5/7-all): 5ths, 3rds, 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, as the detuning of the natural 7th is significant. This mode should
always be used with a Depth of 90% or 100%, as other values render the natural 7th
acoustically ineffective.
• Baroque (3/5-adaptive): This mode tunes pure 5ths and 3rds (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.
• Hermode Tuning:Depth slider: Allows you to set degrees of effect between 0% and
100%.
