From chord MIDI to a piano part that moves
A chord progression can be musically right but still feel static on a piano track. Melody Arranger gives that harmony a playable role: load or capture the chords, select the movement and density that suit the section, then generate a piano arrangement that follows the progression.
Choose the character before you commit
The 157-theme library is organized around four practical piano roles. Open is spacious and sustained, Broken keeps the harmony moving, Chordal adds dense voicings and Active brings more syncopated comping. Hover over a numbered theme for its descriptor, preview options with the DAW transport stopped, then generate the selected direction.
Keep the result editable
Melody Arranger is designed to speed up the draft, not lock it away. The finished result can be saved as a standard MIDI file or dragged into the DAW, where you can change the instrument, edit notes and velocity, or combine the arrangement with your own performance.
