mcp_opendaw_create_taiko_ensemble

Generate a taiko drum ensemble pattern with odaiko, chu-daiko, shime-daiko, and atarigane in openDAW. Choose from five styles and set pitch, velocity, and timing.

Instructions

Create a Japanese taiko ensemble — kumi-daiko group drumming with dramatic dynamics.

Taiko (literally "fat drum") is Japanese percussion with a history spanning over a millennium. Modern kumi-daiko (group taiko) was created in the 1950s by Daihachi Oguchi, combining multiple drum types into an ensemble. The defining characteristic is dramatic dynamic contrast — from near silence to thunderous power — and the use of silence (ma) as a structural element.

The four core instruments:

  1. ODAIKO — The largest drum. Deep, resonant, thunderous. Plays sparse, powerful hits that mark structural points. The "earthquake" of the ensemble. Very low pitch.

  2. CHU-DAIKO — Medium drum. The workhorse — plays the main rhythmic patterns. Mid-range pitch, full-bodied tone. Most of the notes.

  3. SHIME-DAIKO — Small, high-pitched drum. Plays fast, tight patterns and timekeeping. The "metronome" of the ensemble. High, snappy.

  4. ATARIGANE — Hand gong (metal). Plays accents and calls. Bright, metallic, piercing. Used for dramatic punctuation.

Stroke vocabulary (kakegoe): DON — Loud center hit (chu-daiko, odaiko) KA — Rim hit (shime-daiko) DOKO — Double hit (don-ko) TSU — Soft, muted stroke SU — Silence / rest (ma)

styles: "miyake" — Miyake-style: steady chu-daiko pulse with dramatic odaiko accents. Low stance, powerful, sustained. 4/4 with syncopated odaiko on 2.5 and 4. Shime plays continuous 8th notes. Atarigane calls on bar starts. "yatai" — Yatai-bayashi: festival style. Faster, more joyous. Shime plays 16th notes, chu-daiko alternates don/doko, odaiko on downbeats. Atarigane on offbeats. "edo" — Edo-bayashi: Edo period festival. Steady, march-like. Chu-daiko on 1 and 3, shime on all 8ths, odaiko sparse (only on phrase ends). Atarigane sparse. "hachijo" — Hachijo-style: soloistic, dramatic. Long odaiko rolls with chu-daiko accents. Ma (silence) between phrases. Sparse but powerful. Slow tempo feel. "omega" — Modern taiko (Kodo-style). Dense, aggressive, contemporary. All four instruments at high density. Odaiko on every beat, chu-daiko 16ths, shime 32nd rolls, atarigane accents. Maximum energy.

Args: bars: Pattern length in bars (4-32, even). style: Style name (miyake, yatai, edo, hachijo, omega). velocity: Base velocity 0-1. unit_index: AU index. track_index: Note track index. start_beat: Starting beat position. odaiko_pitch: Odaiko (large drum) MIDI pitch (35 = B0). chu_daiko_pitch: Chu-daiko (medium drum) MIDI pitch (38 = D1). shime_pitch: Shime-daiko (small drum) MIDI pitch (42 = F#1). atarigane_pitch: Atarigane (gong) MIDI pitch (50 = D2).

Returns notes created, instrument breakdown, and style info.

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden. It discloses that notes will be created and returns an instrument breakdown, but it does not state whether existing notes are preserved or overwritten, or whether it requires an existing track/unit. The description focuses on musical behavior rather than concrete side effects, leaving some operational ambiguity.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is long but well-organized into clear sections (instruments, strokes, styles, args). Each section adds necessary value for a complex genre-generation tool. Some historical background could be trimmed, but the overall structure front-loads the purpose and remains focused.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 10 parameters and zero annotations, the description provides comprehensive guidance: instrument roles, stroke vocabulary, style-specific rhythmic patterns, all parameter explanations with defaults, and the return value. An agent can confidently select styles and set parameters without needing additional external knowledge.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema provides zero parameter descriptions, but the 'Args' section compensates fully by explaining every parameter with musical context and defaults. Style parameter is exceptionally well-defined with detailed descriptions of each style's rhythmic patterns, and pitch parameters are given default MIDI values.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The opening sentence clearly states 'Create a Japanese taiko ensemble' with further elaboration on kumi-daiko group drumming. It thoroughly distinguishes this tool from sibling percussion tools by providing genre-specific instrument names (odaiko, chu-daiko, shime-daiko, atarigane) and style names.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The extensive style descriptions (miyake, yatai, edo, hachijo, omega) give an agent clear musical context for when to choose each style, effectively guiding usage. However, it does not explicitly mention when not to use this tool or compare it to alternative percussion ensemble tools like create_djembe_ensemble or create_korean_percussion.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
