ChordPilot turns a single note into a chord. In Degree mode every note (snapped to the key) plays the chord of its scale degree; in Progression mode the white keys C, D, E and F are the four chords of the chosen style's progression — you play the whole sequence with one finger, in any octave. Each style has its own harmony: Trap Minor with add9 chords, Drill with the harmonic-minor dominant, Pop, R&B / Neo-Soul with ninths and thirteenths, Dark with the Neapolitan ♭II and Epic with a doubled root. Complexity switches between triads, sevenths, ninths and elevenths, Auto Inversion leads the voices smoothly like a pianist, and Voicing, Bass, Strum and Humanize finish the sound. Notes go to the MIDI output for any instrument, and the built-in sound lets you play right away. Drag the progression or a single chord onto a track as .mid.
