RapidComposer provides multiple methods for selecting chords for the master track or progressions, including the Tonnetz and Circle of Fifths.

Customize chord rules for progressions and apply chord voicings to individual tracks, phrases, or the master track.



The AI assistant, available in both full and light editions, offers intelligent suggestions for chord replacements, progressions, rules, phrases, and even song structure based on the genre or mood you specify. Powered by OpenAI models (such as GPT-4), this feature requires an OpenAI API key for use.

Melodya is a motive generator and editor, which was integrated into Rapid Composer as a Melody Editor tab. By enabling the chords track, you can create a melody for a given chord progression, so two entirely different workflows are supported.
