The record

Purpose: RapidComposer is phrase-based music composition software for composers, songwriters, and musicians.
Composition tools: Its features include phrase and rhythm generators, chord progression editing, melody generation, and melody auto-harmonization.
Chord handling: Phrases automatically conform to chords on the master track, and the software offers chord suggestions and progression generation.
AI assistant: The AI assistant can suggest chord replacements, progressions, rules, song structures, and tracks; it requires an API key, supports multiple providers, and can use local models.
Neural Phrase Engine: The full edition's Neural Phrase Engine generates or continues phrases and multi-track compositions using local AI models.
DAW integration: RapidComposer's plug-in versions work in DAWs that support plug-ins with MIDI output, and tracks or compositions can be dragged and dropped to DAWs.
Instruments and plug-ins: RapidComposer supports VST 2.4 and VST3 instruments and effects, SoundFont, and SFZ.
Trial limitation: The fully functional demo expires after 30 days and does not allow saving or exporting files.
Intended users: The maker describes Light Edition as for hobbyist musicians and Full Edition as for professional composers.
Installations: A license allows three installations, provided they are not used simultaneously.
Offline use and licensing: The maker says an internet connection is not required to run the software and copy protection uses a license key without online activation.
Data protection: MusicDevelopments' privacy policy says it processes personal data under the EU General Data Protection Regulation (GDPR).
Support and updates: The shop lists product support with Light Edition and says updates are released regularly, typically every one to two months.
Maker location: The maker's imprint identifies MusicDevelopments as Mezei Attila E.V., located in Pomáz, Hungary.
