GTK - Guitar Player's Toolkitの注目ポイント
三千六百種類以上のコード収録
膨大な数のコードが含まれるライブラリから、必要な和音をすぐに探し出せます。ナイロンやスチールなど弦の種類に合わせた正確な音で確認できるため、練習の幅が広がります。
指の形や音名から探す機能
押さえる指の形や特定の音の名前から、該当するコードを特定できます。名前がわからない状態でも、視覚的な情報から目的のコードを特定できるためスムーズに練習を進められます。
スケールの比較と視覚的な確認
色分けされたフレットボード上で、最大四つのスケールや和音を同時に並べて比較できます。共通する音の重なりを視覚的に把握しながら、複雑な構造を把握するのに役立ちます。
特定ポジションでの演奏案内
自分が好む位置でスケールを演奏するための案内を確認できます。手の形を動かさずに特定の場所で演奏を続けたいときや、ポジションの移動を減らしたい場面で便利です。

Ver 1.7.4 2026-08-15
New Chords tab in Scales — Show notes from any chord name (type it in) and see all its notes across the whole fretboard, colour-coded per chord with pie-slice dots where two or more chords share a note and the root ringed. Draws on the same curated chord library as ChordMaster
Ver 1.7.3 2026-08-06
• New Scale Sharing tab in Scales - build a list of up to 4 scales and compare their notes on one fretboard, colour-coded per scale with pie-slice dots where two or more scales share a note.
• Scale Sharing bolds and colours each scale's {bold:root, 3rd, and 5th} in its notes list, and rings those same notes on the fretboard — a full ring on a solid dot, or just the relevant slice on a shared pie-slice dot.
• New Highlight Triad Notes toggle in settings under Scale Sharing lets you turn the fretboard ring highlight off for a plainer view.
• Triad Positions has moved from Position Finder to a new Triads tab in Scales, joining the Scale and Sharing tabs - it now shows chord tones across the full 24-fret neck (the fret From/To pickers are gone), with the fretboard scrolling horizontally and fixed string labels to match the other Scales tabs. Use the string-set checkboxes to focus the display. Your saved chord progressions carry over automatically.
• Position Finder is now a single, focused scale-position tool.
• Scales now shows a Diatonic Chords toggle for scales that have one (Major/Minor and their modes, Harmonic Minor/Major, Melodic Minor) — switch between the scale description and its diatonic chord sequence.
• Fixed Dorian, Phrygian, and Locrian descriptions in Scales, which previously showed a generic "Major scale" description instead of their own.
• Scale Sharing bolds and colours each scale's {bold:root, 3rd, and 5th} in its notes list, and rings those same notes on the fretboard — a full ring on a solid dot, or just the relevant slice on a shared pie-slice dot.

Ver 1.7.1 2026-07-15
• Position Finder now shows a Key / Mode toggle when the fretted position isn't the key's own root. This allows you switch between seeing note degrees and colours relative to the key you're playing in (e.g. G) or relative to the {bold:matched mode} (e.g. A Dorian). If you're playing in G, you should still see the option to focus on G scale notes, even if it is in a different mode's position.
• Corrected several inaccurate fret/mode pairings in Position Finder's help sheet Practical Examples - the displayed notes and mode names now match what the tool actually calculates.
• Fixed the Chord Diagrams setting in Settings - it previously had no effect; now renamed 'Show Finger Numbers' and correctly toggles finger-number labels on chord diagrams throughout the app.
• New Marker Colour option (Cyan, Indigo, Mint, or Pink) appears in Settings → Chord Diagrams when Show Finger Numbers is off, letting you choose the colour of the plain position dots.
• Chord Library now shows a notice when your selected tuning isn't standard. Its chord diagrams are curated for standard EADGBE tuning and won't match alternate tunings like Drop D or DADGAD
• Chord Master's Build and Explore tabs now show your current tuning in the navigation bar, confirming that fretboard positions and note names are calculated for the tuning selected in settings.

Many planned updates delivered:
• Redesigned fretboards - strings and frets now render like a real instrument instead of a grid of cells.
• New Fretboard Skin option — choose Dark, Walnut, Rosewood, Ebony, or Maple.
• Scales fretboard now scrolls across the full 24-fret neck previously limited to 12 frets, with string labels staying fixed in place as you scroll.

• Fixed bidirectional arpeggiation Up then Down / Down then Up) in Chord Master and Chord Library — turnaround note now plays correctly on both passes, and notes no longer prematurely mute.
• Fixed slight fretboard string name misalignment.
