RapidComposer is a unique, non-destructive, phrase-based music prototyping software designed for composers, songwriters, and musicians of all musical styles (available for Windows and macOS: Standalone, VST, VST3, AU, AU MFX).
Music Theory Integration
Create chord progressions that sound great even if you've never touched a piano, use piano-style phrases, automatically harmonize melodies, get chord suggestions, load MIDI files with chord detection, use the chord palette or the Circle of Fifths chart - RapidComposer will always help you compose your song.
Smart Phrases
Phrases always conform to the current chord and scale on the master track. Forget about patching notes. Lay out chords on the master track, or just drop a chord progression on top, and with a single key press you'll generate a harmony track with perfect voice leading. Start composing right away!
Phrase Generator
Rhythm and Phrase Generators are used for a variety of purposes. Create monophonic or polyphonic patterns. Generate melodies. Use mutations to non-destructively change phrases. Slice or change the rhythm of existing phrases.
Flexible chord selection
RapidComposer offers several ways to select chords for a master track or chord progression, including Tonnetz and Circle of Fifths. Color chord buttons by consonant, common note, key, or suggestion. Set chord rules for progressions. Apply chord sounds to tracks, phrases, or master track chords.
Creative Tools
RapidComposer will generate a multi-track composition with chords using your phrases based on your settings. It supports different types of workflows, not just when you are out of ideas.
