Your AI can DJ.

Tremor hosts a Model Context Protocol endpoint on the Mac, so Claude Code, Claude Desktop, Cursor or any MCP client can dig your crate, cue the drop, beat-match, scratch and play a kit over the mix. The agent declares each move; Tremor's engine lands it on the beat grid. Everything runs locally, off by default, on with one toggle.
