RapidComposer is a rapid music prototyping software designed for composers, song-writers and musicians of all musical styles.

DAWs are great for mixing and mastering but they are not intended for music composition. RapidComposer is a dedicated application for creative music composers with non-destructive editing and features that you won't find even in the best DAW applications. Not because RapidComposer is better than a DAW; it is a different tool for a different purpose.

Features:

• Unique non-destructive, phrase-based music composition.
• Advanced tools for phrase editing, phrase generation, phrase grouping, motif development, chord progression editing.
• Intuitive drag and drop environment (you can drop chords, progressions, phrases, instruments to the composition).
• Master track with chords (absolute or scale degrees).
• Movable, resizable and transposable smart phrases that always conform to the current chord.
• Phrase and rhythm generators help you to create thousands of musically useful (not random) phrases.
• Extensive scale, chord, guitar chord, chord progression databases.
• Taggable instrument database of all MIDI, VSTi and SF2 presets in one place.
