AChorda – Visual Chord Progressions & Synth Sketchpad
The complete chord progression builder, arpeggiator, and synth sketchpad for musicians.
AChorda is a chord progression builder and arpeggiator for musicians, songwriters, and producers. Explore chords visually on an interactive Circle of Fifths, build progressions, play them back as arpeggios or strummed chords, and shape the sound with a built-in synthesizer — all in real time.
Whether you're looking for a chord app, an arpeggio player, or a synth sketchpad for songwriting, AChorda turns music theory into a hands-on creative tool. One-time purchase, no subscriptions — everything unlocked from day one.
🎼 Interactive Circle of Fifths
Tap chords on a visual harmonic map and hear them instantly. Navigate major and relative minor keys intuitively. Supported chord types include major, minor, and extended harmonic options. Explore harmonic movement visually and build chord progressions by ear.
🧩 Chord Sequence Builder
Build chord progressions visually with unlimited chords per sequence. Set adjustable chord lengths from 1 to 4 beats, add full song sections for complete song structures, and reorder chords with drag and drop. Perfect for sketching and developing complete songwriting ideas.
🎹 Integrated Synthesizer
A dual-oscillator synth with waveforms including sine, triangle, saw, square, pulse, and noise. Shape your sound with detune, octave control, a low-pass filter with resonance, full ADSR envelope, and tempo-synced LFO. Save and manage your full library of synth patches — no setup required.
🔁 Arpeggiator & Playback
Play back chord progressions in real time using different chord playback modes: full chords, strum up, or strum down. Use the built-in arpeggiator with patterns including up, down, up–down, down–up, and advanced and algorithmic patterns. Control tempo, note speed, note length, and metronome for precise playback.
🔗 MIDI Sync with DAWs
Synchronize AChorda with Cubase or any DAW that supports MIDI tempo sync. Route MIDI between the app and your DAW to match tempo and playback in real time, keeping chord progressions and arpeggios perfectly in sync with your project — ideal for integrating AChorda into your production workflow.
📤 Export & Sharing
Export chord progressions as MIDI or audio in WAV and M4A. Export progressions as plain text. Share and manage projects and synth patches with full project library support.
🎯 Who Is AChorda For?
Songwriters exploring harmony and building complete song structures. Producers sketching and exporting chord progressions directly to a DAW. Music students learning music theory visually. Guitarists and pianists practicing chord movement and arpeggios.
