Is Music Studio live?

Yes — it answered the hub's last check (checked 1h ago). It answered 99% of checks over the last 30 days.

Is Music Studio free to use?

Yes — the hub reached it with no key and no payment.

What tools does Music Studio have?

10 tools: play-live-pattern, get-strudel-guide, analyze-harmony, search-music-docs, create-share-link, update-session, convert-abc-to-strudel, get-music-guide, ….

Is Music Studio safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• play-sheet-music reads open 9h ago

  Write a score in ABC notation and play it as sheet music: a melody, a harmonized piece, a multi-voice arrangement or a well-known tune, on any of the 128 General MIDI instruments. Put chord symbols above the notes and add a style (rock, jazz, bossa, waltz, folk...) for drums, bass and chords. The user can edit the score in the player, change its style and instrument, and download WAV or MIDI. The result confirms the parse; it returns no audio. Start with get-music-guide topic 'genres'; 'abc-syntax' and 'instruments' for the rest. The music player renders inline with interactive playback controls.

• play-live-pattern reads unknown 9h ago

  Live-code music in Strudel (TidalCycles mini-notation in JavaScript) and play it in a player the user can edit. Layer drums, bass and melody with stack(): 71 drum-machine banks, 128 GM instruments, synths and a full effects chain. Add .pianoroll() for a live piano roll (or .punchcard()/.scope()/.spectrum(), one per pattern), pass `visuals` for a ready-made animation and `theme` for the editor colours. Each call creates a NEW player. Optional, when you want more (get-strudel-guide topic in brackets): shader backgrounds that follow the music — start with `await initHydra()`, lock to the beat with H(pattern), react to the sound with () => a.fft[0] ('hydra'); canvases, scenes and spoken lines for music videos and films ('stage', 'film'); taps, faders, pads and controls you draw, played by the user; tilt and mic, which follow the phone on the browser player (a chat's frame usually blocks them) ('interactive'); complete pieces ('gallery'). To jam back and forth, or to change a piece while it plays, pass session: true, then use update-session and get-session. The Strudel REPL renders inline with an editable code editor, visualizations, and playback controls.

  Reference and recipes for Strudel live coding. Music: genres (complete templates: techno, house, dnb, ambient, jazz, lofi, synthwave), mini-notation, sounds (synths, 71 drum banks, 128 GM instruments, vcsl samples), effects, patterns, tips (tempo, common mistakes), advanced (samples, wavetables, signals, chord voicings). Visuals: visuals (draw methods, presets, themes), hydra (shader backgrounds, H(pattern), the audio-reactive a.fft). Optional modules — the code is real browser JavaScript: stage (your own canvases, onFrame/onEvent/onTap, say), film (scenes on bars, text, narration), interactive (taps into notes, faders/pads/xy, tilt/mic, remember() for controls you draw, live sessions), craft (what makes a piece land), debugging (what the player reports back), gallery (complete pieces; fetch one with `piece`).

• analyze-harmony reads unknown 1h ago

  Music theory helper: name a chord from notes, guess the key, get a progression, or list what fits a key. Returns both the ABC chord-symbol spelling (for play-sheet-music) and the Strudel form (for play-live-pattern). Tasks: detect-chord (notes -> chord name + what to play next), detect-key (notes or chords -> best key + diatonic chords), suggest-progression (key [+ romanNumerals] -> chord symbols), scale-for-chord (chords -> the scale to improvise over each), key-chords (key -> every diatonic triad, seventh, and chord scale). Use it before writing chord symbols for a style preset, or to check a harmonization.

• create-share-link changes data unknown never probed

  Create a hosted music share link only when the user asks to share or store a piece online. Uploads the supplied score or pattern to MCP Music Studio for 30 days; anyone with the link can view and play it without signing in. Creating the same share again refreshes its expiry. Playback does not require this tool, and a play result's '▶ Play in browser' link already opens the piece for anyone when it fit in the link; this tool gives a short stored link. Provide kind 'score' with score, or kind 'play' with pattern. Never include private information or secrets.

• update-session changes data unknown never probed

  Only for a live session. Swaps new code into the session's player while the music keeps playing. Send the WHOLE pattern, as for play-live-pattern. It lands on the next bar (quantize 1, the default), the next multiple of n bars, or at once (0): set quantize to your phrase length (8-bar phrase → 8). If the player answers within a few seconds, the result says whether it ran the code, or its error. To change a piece's remember() state, ship a merge, not a new start value (get-strudel-guide topic 'interactive').

• convert-abc-to-strudel reads unknown 18h ago

  Turn an ABC melody into Strudel mini-notation so a scored piece can be remixed live. Returns runnable code — setcps() from the Q: tempo, one [...] bar group per bar inside note("<...>"), with a chord("<...>").voicing() layer stacked alongside it when the ABC has chord symbols (one stack(), because Strudel plays only the last expression) — then pass it to play-live-pattern. Durations become @ weights, rests become ~, triplets nest, the key signature is folded into the note names, and %%MIDI program picks the sound. Lists what was lost (grace notes, dynamics, repeats, lyrics, other voices, inline tempo changes, a short final bar, ABC's own gchord/drum accompaniment). Pick a single voice with `voice`; re-run per voice and stack() them for a full arrangement.

• get-session reads unknown 1h ago

  Only for a live session (play-live-pattern session: true). Reads whether the player is up and what it played, its errors and silences, and what the human did since your last read: taps, changes to remember() state, code they ran, a Pass to you, or End. Read it before assuming a piece played. With wait: 'pass' it listens until the human presses Pass, so a whole back-and-forth set fits in one turn: update-session, get-session(wait: 'pass'), answer, listen again.
