SFINX - Xenharmonic Guitar Learning App
(Stringed Fretted Instruments Notes Explorer)
Free Web based App for:
-Generating scales and chord diagrams for xenharmonic(micro/macro-tonal) guitars.
-Interactive virtual guitar to play and find chord progressions.
-Tuner and fret-board calculator.
Help:
Default presets include normal 12ed2 guitar and bass.
Presets are saved per browser. Import/Export settings. Saving an instrument preset or a scale with existing name overwrites it. Saving scales doesn't automatically save the instrument, after adding/creating scales, save the preset too.
Strings: Amount of strings of the instrument.
Frets: Amount of frets of the instrument.
Tuning System:
Decimal Ratio List: The program accepts list of intervals in decimal ratio, comma-separated.
If you have the ratios/fractions:
11/10 6/5 3/2 17/10 2/1
Do the division.
1.1, 1.2, 1.5, 1.7, 2
The last number is the equave, like Scala files.
And there is included an equal-division calculator.
Divisions: Amount of divisions in the tuning.
Interval: The interval being divided. (2 is octave, 2:1).
Top-right options, Width, Length, and Zoom, only affect the graphics, not the tuning nor sound.
Tuning Pattern:
Each string you add, also adds a control on its left that sets the open string note in relation with its previous string (that is why the lowest string doesn't have one).
The standard guitar tuning pattern is 5, 5, 5, 4, 5 (The fret you use to tune the next string)
But if the lowest string doesn't have a control, how to make a drop?
A one step drop tuning pattern is: 7, 5, 5, 4, 5. You don't need to control the first.
The rulers:
-The interval ruler (pink) marks always the equave.(the last number in the interval list, or the interval used for division in equal-division system)
-The fixed 12ed2 ruler (green) is useful to measure other tunings, since most musicians are familiar with the role of those tempered 12, is easy to relate new tunings using the ruler for quick comparison.
Highlights:
Each interval on the list gets a control, or with the equal-division system, each division gets a control.(Note: with non-integer divisions, this gets truncated, floored. So with 11.66 divisions, it will count 11, this is non-sense, yes).
Here is where you set the scale to be displayed on the fretboard.
Each marked note, adds a control for arpeggiate a chord.
Chord Pattern:
Each string added, adds a control for selecting a note for the chord-row.
Colors by:
Single: Plain color.
Rank: Notes get a unique color by its rank.
Row: Colorize by chord row, controlled by the chord pattern.
Calculator ruler: Displays a ruler (orange) with the relative size of the string when hovering a fret.
Size: Sets the nut to bridge length for calculations.
Arpeggiator: simple Up, Down, Con, Div options.
Speed: Arpeggio note separation speed in seconds.
Lowest Pitch: In hertz. Sets the lowest possible pitch, that is the lowest open string, the only control for setting pitch directly.
Note Length: Controls the length of played note.
Synth Sound: Select a sound for the interactive guitar.
and Volume.
