Why Reaper for Rock
For dedicated Reaper users focusing on rock production, speed and precision are critical.

By using specific prompt crafting—describing note patterns and rhythmic instructions—you ensure the generated rock melody aligns perfectly with your vision. If you've laid down a strong foundation but need variations, the Continue Existing MIDI function is essential. Simply input 1-2 bars of your existing riff and generate short, coherent continuations, allowing you to quickly iterate and find the perfect extension for your rock track. Even valuable audio snippets can be converted; the Audio to MIDI capability allows you to extract musical ideas from clean guitar or acoustic performances, providing editable MIDI tracks for refinement. MIDI Agent is installed as a VST3 and appears directly in your FX browser in Reaper, streamlining your workflow and providing a powerful Rock MIDI Generator for Reaper tool without ever leaving your project.
