Compose and edit structured MIDI music in five styles, shape dynamics with CC automation, preview it in a piano-roll player, render and play WAV in your browser right in the chat, and download MIDI. No account needed.
Compose a new piece with GBK Composer — create a durable composition, inspect and refine it, render it, and present the player with WAV/MIDI downloads. Use when the user asks to compose, write, or generate new music.
Revise an existing GBK composition — targeted, revision-safe edits to specific bars, tracks, orchestration, dynamics, or mix that preserve everything else. Use when the user asks to change, fix, or develop a piece that already exists.
Render a GBK composition to validated WAV and MIDI — submit the job, poll to completion, verify the artifacts, and return authorized download links. Use when the user asks to render, export, hear, or download a piece.
