Four experts. One co-pilot.

Sound Copilot adapts to your role in the session—whether you are writing, designing, theorizing, or finishing.

Producer

Arrangement & Dynamics

Shape song structure, groove, and energy curves without leaving the timeline. Get intelligent suggestions for builds, drops, and dynamic contrast that respect your genre.

Sound Designer

Synthesis & Textures

Dial in timbres, modulation chains, and atmospheric layers. Sound Copilot understands spectral balance and helps you sculpt unique textures faster than menu-diving.

Music Theorist

Harmony & Scales

Navigate modes, voicings, and voice-leading with confidence. From jazz extensions to film-score modulations, harmonic guidance stays musical—not academic.

Mix / Master Engineer

Surgical EQ & LUFS Target

Pinpoint problem frequencies, balance stems, and hit loudness targets with precision. Integrated LUFS awareness keeps your masters streaming-ready.

Built for REAPER. Built to last.

Sound Copilot is a native C++ extension—no Electron wrappers, no web views. Low latency, tight REAPER integration, and platform-native binaries for professional workflows.

Important — AI usage is separate

Your Sound Copilot license is a one-time, perpetual purchase. AI-powered features are not bundled: you connect your own API key and maintain a subscription (or pay-as-you-go plan) directly with your chosen provider—OpenAI, Anthropic, OpenRouter, or another compatible service. Usage fees are billed by that provider, not by Hommel Sound. API key setup, agents & cost guide
