Ukulele Toolkit supports many advanced settings to customize its display and usage. We’ll explain those settings in this chapter.
 Left Handed: Left Handed setting is especially designed for left hand users. Once after you highlight the option, all interfaces in Ukulele Toolkit will be changed to Left Handed Mode. For example, the string of tuner will flip right to left in Left Handed Mode.
 Capo: Capo is a device used on the neck of a stringed (typically fretted) instrument to shorten the playable length of the strings, hence raising the pitch.
For example, fingering of C# will be the same with C if you capo is on the first fret.
 Letter Notation: Ukulele use letter notation by default, thus all the note displayed will be Note-based. However, if the option is un-highlighted, notes will be displayed based on intervals. For example, C# Chords will be displayed as G#-C#-E#-C# when it is Notation based, however, 5-R-3-R is used when it is Intervals based.
 Tuner Noise Reduction is enabled to reduce the influence of noise to Tuner, so Tuner is less sensitive to noise.
 Strumming Indicator: Select different indicators will affect the Strumming Mode discussed in Chapter 4. If DU is selected, the strumming block will be displayed as DU mode, while conversely, the selection of arrow option in Settings will make the strumming block displayed as up-down arrow.
The images bellow show two different displays generated by Strumming Indicator settings.
 Show Arpeggios For Chords: Chords and Arpeggios sometimes are strongly connected. Highlight this option will enable the Chords Details Interface (Chapter 6) to display all arpeggios for this chord (Right Image). On the contrary, the interface will only show the notes in a specific fingering (Left Image).
 Do Not Play Chords Arpeggios: If this option is highlighted, Ukulele Toolkit will play one strumming sound if you tap the chord diagram. Conversely, it will play a strumming sound + arpeggio sound.
 Instrument：Ukulele Toolkit supports 3 widely used Ukulele tuning modes. They are C Tuning, D Tuning and Baritone Tuning, correspondingly. The default tuning mode is C Tuning.
If you are using other tuning mode rather than C Tuning, you can switch to other tuning modes by selecting other options. All displays and functions related to tuning modes (Tuner, Scales, Chords) will be changed.
 Concert A, aka. A4 or A440:
A440, which has a frequency of 440 Hz, is the musical note A above middle C and serves as a general tuning standard for musical pitch.
In the detail page of the A4 Calibration, you’re allowed to input the frequency directly by press + and – button , or select a specific frequency . The accuracy of A4 calibration is 0.1Hz. Once after A4 is changed, all of the sound playing and detection parameters will be changed correspondingly.
