Implementation Reference
- src/services/PatternGenerator.ts:246-256 (handler)Core handler function that implements generate_polyrhythm by stacking individual Euclidean rhythms (using Strudel's .euclid) for each provided sound and pattern length over 16 steps.
generatePolyrhythm(sounds: string[], patterns: number[]): string { if (sounds.length !== patterns.length) { throw new Error('Number of sounds must match number of patterns'); } const rhythms = sounds.map((sound, i) => { return `s("${sound}").euclid(${patterns[i]}, 16)`; }); return `stack(\n ${rhythms.join(',\n ')}\n)`; } - src/server/EnhancedMCPServerFixed.ts:482-492 (registration)MCP tool registration in getTools(), including name, description, and input schema defining sounds (array of strings) and patterns (array of numbers).
