Effortlessly craft rich chord progressions and utilize piano-style phrases, even without prior piano experience. Auto-harmonize melodies, receive chord suggestions, and load MIDI files with built-in chord detection. With tools like the chord palette and the Circle of Fifths chart, RapidComposer provides constant support to enhance your songwriting process.
Phrases automatically adapt to the current chord and scale on the master track, eliminating the need to adjust individual notes. Simply lay out chords on the master track or drop in a chord progression, and with a single keystroke, generate a harmony track with flawless voice leading. Start composing with ease today!
Included rhythm and phrase generators allow for creating a wide range of patterns, both monophonic and polyphonic. Generate melodies, apply variations to modify phrases non-destructively, and easily slice or adjust the rhythm of existing phrases.
Leverage an intelligent algorithm to generate optimal guitar chord fingerings based on your specific constraints. Easily edit fingerings directly on the fretboard. Convert tracks into editable guitar tablature with calculated, optimized fingerings. Export tabs seamlessly in MusicXML format for further use.
Suggestions by harmonic rules, borrowed chords, chord substitutions, pivot chords, diatonic and chromatic mediant chords, passing chords, bass and melody pedal tone chords, chords on scale, chord builder, chord voicing editor. With these tools, you'll always have guidance for selecting the perfect chords.
RapidComposer provides multiple methods for selecting chords for the master track or progressions, including the Tonnetz and Circle of Fifths. Chord buttons can be color-coded by consonance, common tones, tonality, or suggestions. Customize chord rules for progressions and apply chord voicings to individual tracks, phrases, or the master track.
With it, you can instantly create new multi-track compositions or phrases, or even let the engine continue an existing melody or arrangement. It’s a powerful way to spark creativity and explore new musical ideas inside RapidComposer.
* Full Edition only
Trigger and perform sections of your composition from a MIDI keyboard in real time, with per-track speed, transpose, and timing controls. Mouse triggering also supported. With LIVE Playback Mode in RapidComposer 6, your compositions are no longer static: they become expressive, playable instruments.
* Full Edition only
The AI assistant, available in both full and light editions, offers intelligent suggestions for chord replacements, progressions, rules, and even song structure based on the genre or mood you specify. Powered by AI models from multiple providers, this feature requires an API key from a supported service.
RapidComposer generates multi-track compositions with chords based on your settings and phrases, supporting a variety of workflows. It's designed to inspire creativity, even when you're not short on ideas.
* Full Edition only
Melodya is a motive generator and editor, which was integrated into RapidComposer 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.
* Full Edition only
The extensive libraries for chords, scales, and chord progressions are fully expandable. Use the docked browsers to search, preview, sort, group, and display items. Additionally, a file browser and a CC envelope browser have been included for enhanced navigation.

OpenWire is an open-source library designed for Arduino and other microcontroller platforms. It enables the creation of complex, interactive systems by allowing devices to communicate with each other in a flexible and efficient manner. The library is built around a simple, yet powerful concept: devices can send and receive data packets, called "events," which can trigger various actions and responses.
