Kiwisonic

Why Kiwisonic?

Built for composers, not engineers

Most music tools expect you to already know what you're doing. Kiwisonic starts from the other end.

vs. DAWs

Hundreds of knobs and panels before you place a single note
No concept of key or scale built into the interface
Designed for recording and mixing, not composition
Hours of tutorials before you hear anything

        
          Kiwisonic
        
        Built for melody and composition — that's all it does
Snap-to-scale means you can't place a wrong note
Music theory runs quietly behind every tool
Genre blueprints from the catalog give you a starting point that already sounds right

vs. Trackers

Notes as rows of hex codes in a spreadsheet
No harmonic guidance — every choice is on you
Steep cultural learning curve before anything sounds musical
Interface built for precision, not inspiration

Feature Highlights

What you get

A focused set of tools that help you write music — without needing to study theory first.

Flow Chord Pad

A 3×3 grid showing which chord fits next, color-coded by how well it follows. Press a numpad key, place a chord. You can build a full progression in seconds.

Guided Melody Editor

Shows only the notes in your scale, color-coded by how well each one continues from what you just played. No wrong notes to worry about.

Melody Generators

Three algorithms that generate melodies in your key and genre. Use them as a starting point, then edit until it sounds like you.

Lock & Reroll

Keep the notes you like, lock them in place, and regenerate the rest. Refine gradually instead of starting over each time.

Phrase Contour

Draw the shape of a melody — rising, falling, holding — and the engine fills in notes that follow your curve. You sketch the feeling, Kiwisonic finds the notes.

Genre Blueprints

Pop, Lo-fi, Trap, Jazz, Synthwave, and more — delivered through the catalog and growing. Each one sets scales, chords, tempo, and melody character so you start with something that already belongs to a genre.

Snap-to-Scale Piano Roll

Choose a root note and scale. The piano roll dims out-of-key notes and snaps your input to the scale. Everything you place sounds right together.

MIDI Export

Export your song as a standard MIDI file and open it in any DAW — Ableton, FL Studio, Logic, Reaper. Compose here, produce there.
