Music theory, right on your fretboard.

To understand where the notes of a solo or riff come from, and stop memorising positions.

• More than twenty scales and modes: major, natural, harmonic and melodic minor, Greek modes, altered modes, pentatonics and blues
• Notes, intervals or degrees on the fretboard; one colour per note, the root as a square, the third as a diamond
• Free tuning and string count, for guitar, bass or other string instruments
• “Scale for chord”: shows the scale that fits the chosen chord
• Drone, backing and tablature view reachable from the module

To find a shape, understand how it is built and know which scales it sits on.

• More than twenty types: major, minor, power chord, sus2, sus4, add9, sixth, min6, sevenths, ninths, eleventh, diminished, half-diminished, augmented
• Shapes on the fretboard (open or movable) with the interval stack
• Colours by note or by interval; listen to each chord
• List of scales compatible with the chord; add it to a progression in one gesture

To play and see chords on small string sets, in every inversion.

• Major, minor, diminished, augmented
• Root position and inversions, on groups of three strings
• Role of each note (root, third, fifth) shown by shape and colour
• Choice of the bass string

To learn to recognise and place intervals without counting frets.

• The twelve intervals, from unison to major seventh, with their name and semitone count
• Move the root to see the same interval everywhere
• Quiz mode to practise

To understand neighbouring keys, key signatures and the chords of each key.

• Key, number of sharps or flats, relative minor or major
• Diatonic chords with numerals (I, ii, iii, IV, V, vi, vii°), dominant and subdominant
• Major and minor modes; click a note to hear it, with octave choice

To assemble a progression, see how chords relate and look for a melody on top.

• Three input modes: chords, notes, melody
• Root and more than fifteen chord qualities (sus, add9, sixth, sevenths, ninths, diminished, augmented…)
• Progression built step by step, with templates such as I–V–vi–IV or the blues

To find a sequence that works, understand each chord’s function and play along.

• Progression catalogue and chord bank
• Diatonic mode (chords of the scale) or free; borrowed chords (bVI, bVII, iv…)
• Listening and backing; MIDI input possible

To recognise by ear what you see on the fretboard.

• Rhythm: rhythmic dictation to rebuild, three difficulty levels, score
• Intervals, chords, scale degrees, cadences and scales
• Listen, answer, check, new exercise in one click

To work on the strumming or picking hand: patterns, accents, swing.

• Rhythm generator (for example D-DU-UDU) with adjustable time signature, subdivisions and swing
• Editor: down, up, muted, rest, on each subdivision
• Pattern library sorted by genre (pop, folk, rock, punk…) and by level
• Sound from samples or synthesis

To work on pulse, from the first slow tempo to advanced training.

• Tempo, tap tempo, accents adjustable beat by beat
• Swing and human feel, tempo ramp, random beat mute to test your steadiness
• Session timer, savable presets, visual flash and vibration, full screen

To work on intonation, the colour of a mode, or to sing over a tonic.

• Note and octave of your choice, frequency shown
• Timbres: sine, sawtooth, square, triangle, bell
• Held chords: major, minor, sevenths, sus, add9, diminished, augmented

To identify a chord, notes or a rhythm from what you place or play.

• Harmonic: place notes on the fretboard (frets, open string, muted string) to get the chord, notes and intervals
• Audio listening and MIDI input
• Rhythmic: tap tempo and analysis of the rhythm you play

To note an idea, learn a piece or prepare course material.

• Editing, playback and library, free tuning
• Techniques: hammer-on, palm mute, let ring, bend…
• Copy, paste, add beats and bars; playback with adjustable tempo and speed
• Examples included; video export of tabs

To start an idea without a blank page.

• Pick a genre: blues, pop, rock, jazz, folk, country, R&B, metal, reggae, bossa, latin, classical, funk
• Add a mood: bright, tender, melancholic, restless, triumphant, suspended, dark, airy
• Or let the app surprise you

To play over a backing built from your chord grid, without recording tracks.

• Sections (verse, chorus…), bars and chords per bar, structure loops
• Rhythm per track: nylon, steel, baritone, clean/crunch/overdriven/jazz electric guitar, ukulele, piano, sitar, harp, dulcimer
• Styles and rhythms of your choice, backing generated from the grid

To build drum and percussion patterns and practise over them.

• Step grid per instrument: kick, snare, hi-hat, percussion, cymbal
• Pattern bank from A to H and song mode to chain them
• Drum kits and starting genres, automatic generation and pattern learning
• Send the result to the backing

To write melodies and lines, play them back and rearrange them.

• Piano-roll with entry by mouse, computer keyboard or MIDI
• Scenes A to H that can be chained, tracks with effects and sounds of your choice
• Idea generation, notebook, transfer to the other modules

To play the screen like an instrument, or drive your synths and DAW with a controller built to your needs.

• Pages made of freely arranged zones: grid of pads by scale degree, piano, drum pads, looper, arpeggiator
• Orbital wheels: seven scale-based layouts (tour, safe notes, pentatonic, modes, lock, duo, T-S-D functions), chained chords, continuous glissando
• Modeled strings: guitars, bass, ukulele, harp, violin, cello, erhu — pluck, bow, slide
• Expression: finger pressure, position and movement shape the sound; gesture vibrato
• MIDI controller: MIDI output (including MPE), keyboard routing per zone, key ranges, MIDI in and out on computer and Android
• Per-zone effects (chorus, delay, reverb…), ready-made page templates for solo, two-player or looping
