The Soundbox studio: a script cast across three speakers above a multi-track timeline holding the spoken lines, an ambient music bed and sound effects, with the library panel on the right

The Music page: a request form with model, licence, styles, tempo, key and length beside a shelf of generated takes

The SFX library with waveforms, models and seeds, and the prompt composer

The Agents page: connected MCP clients, copy-paste connection commands, and a log of recent calls

The same prompt and seed rendered by Stable Audio 3.0 Small Music, MiniMax Music 3 and ACE-Step 1.5 Turbo, with measured render times on an RTX 5080
