Play one string at a time — it auto-detects which string you're tuning (or click a string to lock it; AUTO unlocks). The arrows tell you to tune up or down; hold it in tune and you get a beep + ✓. Clicking a string also plays its reference pitch.
Melody sketchpad — piano roll: paint notes, loop it, morph it between modes
FL-style roll: click a cell to add a note, click again to remove, drag to paint. Each cell is a 16th note; stack cells in a column for chords. Blue rows are in the current scale, the red-edged row is the root. ● Rec step-records clicks from the piano/fretboard into the grid. Loop it with ▶ Melody in the bottom bar; Morph replays the same grid in a parallel mode.
Rotations — same notes, shifted emphasis (click a row to switch)
🔎 Same notes & scale finder
Scale finder — pick notes, see every scale that fits
The first note you pick is treated as the root (★) and those scales are listed first. Tip: in the fretboard card set “Clicking a note → adds it to the scale finder” to pick notes straight from the fretboard, piano or note chips. Click any result to open it.

Positions
Shape movement — how a shape slides when the root changes
Move→
Grey = the shape at the “from” root. Colored = the exact same shape at the “to” root. The pattern never changes — it only slides along the neck by the interval between the two roots. (Same fingering, new position.)
Diagonal run — play the scale diagonally across the neck

Spice — borrowed chords & secondary dominants
Arpeggio targeting — chord tones on the fretboard
While the progression plays, this board follows the current chord: bright dots are its chord tones (red = chord root), faded dots are the rest of the key. Land on bright dots on strong beats and your lines will always sound intentional.

Mic modes: play the target on your guitar — three clean readings = hit, a wrong note resets your streak, streaks add bonus points. Find the note accepts any octave; Exact note wants that precise octave (only its positions are lit). Name the dot needs no guitar: pick the note name and octave of the glowing position. Finish a round to set a best score.
Fretboard memory — every note with its octave
Memorize tip: start with Natural notes only, then use Only one note… to find every C (or Do) on the neck, then Hide names and click dots to check yourself. Click any dot to hear it.
