mcp_opendaw_create_dembow

Create a dembow rhythm—the 3-3-2 syncopated pattern that drives reggaeton and Latin dancehall. Choose from classic, dancehall, trap latino, perreo, or urbano variants.

Instructions

Create a dembow rhythm — the foundational beat of reggaeton and Latin dancehall.

The dembow is a 3-3-2 syncopated pattern that drives virtually all reggaeton and Latin dancehall music. It derives from the "Dembow" riddim by Bobby Dixon (1990, Jamaica) and was popularized in Puerto Rico. The pattern creates a distinctive galloping feel through its uneven grouping of 3+3+2 within a 4/4 bar. Every reggaeton track from Daddy Yankee's "Gasolina" to Bad Bunny's "Tití Me Preguntó" is built on this rhythm.

dembow_type: "classic" — Classic reggaeton dembow. Kick on 1 and 3, snare on 3.5, 4.5, 5.5 (the 3-3-2 gallop). 1-bar cycle. "dancehall" — Dancehall variant. Sparser, kick on 1 and 3, snare on 3.5 and 4.5. Less gallop, more pulse. "trap_latino" — Latin trap variant. Kick on 1, 3.5, and 4.75 (syncopated), snare on 2.5 and 4.5. More modern, less rigid. "perreo" — Perreo (old-school reggaeton). Denser snare pattern with ghost hits on 2.75 and 6.75. Rougher, underground feel. "urbano" — Urbano latino (modern fusion). Kick on 1, 3, 4.75, snare on 3.5, 4.5, 5.5. Blends reggaeton with trap.

bars: Pattern length (1-16, 1 = one bar cycle). kick_pitch: MIDI pitch for kick (36 = C1, acoustic bass drum). snare_pitch: MIDI pitch for snare (40 = E1, electronic snare). velocity: Base velocity 0-1. Ghost hits -0.2, main hits +0.05.

Returns notes created, dembow type, and stroke breakdown.

Example: create_dembow(dembow_type="classic", track_index=0) create_dembow(dembow_type="trap_latino", track_index=1, bars=4)

Behavior3/5

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

No annotations are provided, so the description carries the full burden. It explains the dembow pattern and parameter effects but does not disclose side effects like overwriting existing notes, requiring a track index, or potential destructive behavior. The return value is mentioned but not where the notes are placed.

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

Conciseness3/5

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

The description includes a lengthy historical background and cultural references that, while educational, are not essential for tool usage. The parameter listing is well-structured with bullet points, but the overall length could be trimmed. Every sentence does not directly earn its place for an AI agent.

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

Completeness3/5

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

Given 8 parameters and no annotations, the description covers the most important aspects but misses key details like where the notes are placed (e.g., track_index is required but not explained), and whether the tool replaces existing content. The output schema is indicated but not described.

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

Parameters4/5

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

Schema coverage is 0%, so the description must compensate. It provides detailed explanations for dembow_type with 5 variants, and explains bars, kick_pitch, snare_pitch, and velocity with real-world context. However, start_beat, unit_index, and track_index are not documented, leaving some parameters unexplained.

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 description clearly states it creates a dembow rhythm, the foundational beat of reggaeton and Latin dancehall. It explains the pattern origin and structure, and the specific verb 'Create' plus resource 'dembow rhythm' is distinct from sibling tools like create_clave or create_breakbeat.

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

Usage Guidelines3/5

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

The description does not explicitly state when to use this tool versus alternatives. It describes the tool's purpose and parameters but lacks guidance on context, prerequisites, or exclusions. The agent must infer usage from the name and description alone.

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