Generate Music in Reaper with AI
Stuck in a creative loop? The MIDI Agent VST is the essential tool for music producers seeking to instantly expand their compositional toolkit directly within their DAW. As an advanced AI MIDI Generator for Reaper, MIDI Agent solves the challenge of generating fresh musical ideas efficiently. Our core feature, AI-Powered MIDI Generation, allows you to generate complete melodies, intricate chord progressions, and full compositions using simple natural language prompts. Imagine defining the desired key, scale, length, and complexity, and having the AI deliver usable MIDI in real-time right in your session. Beyond starting from scratch, MIDI Agent offers powerful continuation features: Continue Existing MIDI allows you to drop in existing files to generate variations, ensuring musical coherence while extending your tracks. Furthermore, the innovative Audio to MIDI function enables intelligent transcription, letting you extract complex harmonies and rhythms from recorded audio samples directly into editable MIDI data. This integration streamlines workflow, ensuring that creative inspiration—whether textual, existing MIDI, or recorded audio—is immediately translated into production-ready MIDI.
Why Reaper
For dedicated Reaper producers, efficiency and rapid iteration are crucial. MIDI Agent directly addresses the time sink often associated with programming complex musical parts. When you need a quick variation on a theme, the Continue Existing MIDI feature is invaluable; simply input 1-2 bars and iteratively generate short, coherent extensions. This eliminates manual editing and keeps the creative momentum flowing. If you’ve captured a great idea on an acoustic instrument, the precise Audio to MIDI transcription capability lets you instantly extract musical ideas from the recording, converting complex rhythms and harmonies into editable MIDI. Furthermore, the flexibility offered by Flexible API Options means you can integrate your preferred AI service providers (like OpenAI, Anthropic, or Google Gemini), or opt for the MIDI Agent Pro subscription for managed access to exclusive providers like Google AI Lyria 2. This ensures that the advanced capabilities of an AI MIDI Generator for Reaper are always tailored to your specific production environment, providing immediate, high-quality results for any genre.
