What's new in 1.3
Clearer charts
Barre chords now draw the bar over the dots the way real chord books do. Fret numbers moved clear of the markers that covered them, and the nut is solid instead of see-through.
Build solo sheets faster
Chord Voicings, Arpeggios and Triads each carry the full Root, Type, Bass note and search controls. Swipe an item left to remove it, and reopening a sheet brings everything back exactly as you left it.
More ways to write
23 genres of proven progressions, modal progressions built from the mode you pick, and a random generator that only draws from progressions that work.
On iPad
Solo sheets can show their diagrams in two columns, and the layout carries into full screen.
Fixes
Faster launch. Note names now appear on song-sheet scale and arpeggio diagrams, and the interactive fretboards no longer sound a chord when touched.
