Toy DAW is a real music workstation. Ask your agent for “a 90 BPM lo-fi beat” and it builds channels, writes notes, arranges and mixes right in the window. You see every step, and you can pause it, undo it or take over at any point.
// 01 — The visible agent
The agent uses the same channels, patterns and mixer tracks you do. Everything it does lands in the project, where you can hear it, change it or undo it. Where it stops, you carry on.
Whatever pattern and channel the agent writes to, the window goes there. New notes are drawn one by one in musical order, and the status strip names the step it is on.
The agent shares your undo history. Pause it from the status strip, undo its whole batch with one click, and read what it did in the activity log.
// 02 — A complete DAW
Four pattern-based editors with a built-in synth, SoundFont player and more than a dozen effects. Without an agent it is still a DAW you can make songs in.
Fifteen chord types with inversions in one click, 808 and growl slides written directly, ⌘-marquee then right-click for velocity, length, chop and quantize.
Intro, drop and break at a glance, and the agent understands “change the bass in Drop 2”.
Factory wobble, growl, screech and reese sounds to start from.
Reverb and delay on sends, the kick ducking the bass. mix_check measures the problems first; mix_assist then mixes rule by rule, each step undoable on its own.
// 04 — Bring your agent
While it is open the app serves MCP on your machine with 54 tools: read the score, write notes, music-theory generators, arranging, mixing, render and measure, export. Local only, token required.
