Most music tools expect you to already know what you're doing. Kiwisonic starts from the other end.
A focused set of tools that help you compose, arrange, and export.
Write chord progressions from your numpad. A 3×3 grid shows all chords in your key, color-coded by how well they follow the last one you placed. Green fits smoothly, yellow adds color, red creates tension. The colors update after each pick.
Place chords above any editor to define the section's harmony. Every tool adapts: melody suggestions promote chord tones, the bass generator follows roots and fifths, and note durations respect chord boundaries.
Click to place notes, drag to resize. Out-of-key rows are dimmed so you can see what fits at a glance. Ghost notes from other tracks appear behind your own, so you can write parts that complement the full arrangement.
Pick a genre and Kiwisonic configures scales, chord preferences, rhythm feel, tempo, and instruments to match. Each profile includes pattern presets for drums, bass, guitar, strings, and wind, tagged by section type.
Seven editors built around how each instrument is played. Guitar with strum patterns and voicings. Bass with chord-aware generation. Strings with bowing and articulation. Wind with tonguing and pitch bends. Drums with a step sequencer.
Fifteen built-in effects per track, from compressor and saturation to delay and reverb. Section-level effects let you keep a verse dry and add space in the chorus. Twelve built-in synths and a TR-808 drum machine are ready to play.
You know your chords but not always what comes next. The Flowpad and Circle of Fifths show you what works. The guitar editor handles strum patterns and voicings so you can focus on the progression.
DAWs feel overwhelming. Kiwisonic lets you pick a genre, place notes that sound right together, and build a full arrangement with drums, bass, and melody from one screen.
You want a quick way to sketch song ideas before moving to your production setup. Export to MIDI or WAV, or load your own VST3 plugins and SFZ instruments directly.
