Why we built Kiwisonic

A songwriter who tried everything and ended up building the tool that was missing.

A songwriter looking for the right tool

It started with lyrics. Words on a page, a melody in my head, and a desire to actually hear the song — not just imagine it. So I tried the obvious first step: AI music generators. Feed them the lyrics, get something back.

The results were fine. Technically competent. But everything sounded the same — polished, predictable, and unmistakably mainstream. The AI had no idea what I was going for. It was generating music, not helping me realise mine.

"I didn't want a generator to write my song. I wanted a tool that understood music theory well enough that I could write it."

Then I found Hookpad. A piano roll with music theory built in. The chord palette knew your key. The melody editor highlighted valid notes. It was the first tool that felt like a conversation about harmony rather than a blank page.

But Hookpad has a ceiling. It handles melodies and chord progressions well, but it stops there. No drums, no full arrangement, no way to hear an actual band. The moment you want more than a melody sketch, you've run out of road.

So I opened FL Studio. It immediately felt like walking into the engine room of a ship. Every knob does something important. None of it is labelled for a songwriter. Setting up a single instrument track took longer than writing the chorus had.

I wanted something in between. The harmonic intelligence of Hookpad, with enough depth to build a full composition — drums, guitar, multiple instruments, a real song structure. Not a production suite. Not a toy. A composer's tool.

That gap is what Kiwisonic is built to fill.

The golden middle path

Hookpad showed what music theory in an interface can feel like. FL Studio showed what full composition depth looks like. Kiwisonic tries to have both — without the ceiling of one or the overwhelm of the other.

Pick a key. Pick a genre. Build a song section by section — melody, chords, drums, guitar. Export it as MIDI and take it wherever you need to go next. The theory stays hidden. The music stays yours.

Kiwisonic is for you if…

You are… Your situation How Kiwisonic helps
A guitarist You want to write a full song but don't know which chords go together in a key Chord suggestions and the Circle of Fifths show you the harmonic options for your key visually
A beginner producer DAWs feel overwhelming — hundreds of controls before you've placed a note Genre profiles and melody generators give you a musical foundation in seconds, no setup required
A melody seeker You know what you want a melody to sound like, but you can't quite find the notes Snap-to-scale and melody generators help you find notes that match your instinct
A theory student You want to hear theory concepts immediately — not just read about them Kiwisonic makes scales, chord progressions, and voice leading immediately audible
An intermediate musician You need a fast, focused sketchpad before moving ideas into your full DAW Compose a full section-based song structure and export as MIDI for your DAW to take over

What Kiwisonic can't do (yet)

Kiwisonic is a composition tool, not a production suite. Here is what's outside its current scope.

Limitation Notes
No audio recording Kiwisonic is MIDI and instrument-based only — you can't record your voice or a live guitar into it
No audio effects No reverb, EQ, compression, or mastering chain — use a DAW for final production polish
No sheet music / notation Notes are in the piano roll only, not staff notation
Windows only The audio engine currently uses Windows-specific APIs; Mac and Linux are planned
Limited MIDI automation No parameter automation curves (e.g., filter cutoff over time)
No mid-song time signature changes A song has one global time signature
No audio export Export is MIDI only — bounce to audio in a DAW
Guitar chord track playback The guitar chord track editor is built but not yet connected to live playback
No collaboration Single-user — no cloud sync or real-time collaboration

These are deliberate scope choices. Kiwisonic focuses on composition and does that well.
