Implementation Reference
- Handler function for the 'stretch' tool. Validates the factor, retrieves the current pattern, appends .slow(factor) to stretch it temporally, writes the modified pattern, and returns a confirmation message.
case 'stretch': InputValidator.validateGain(args.factor); // Positive number, use gain validator for simplicity const toStretch = await this.getCurrentPatternSafe(); const stretched = toStretch + `.slow(${args.factor})`; await this.writePatternSafe(stretched); return `Stretched by factor of ${args.factor}`; - src/server/EnhancedMCPServerFixed.ts:171-181 (registration)Tool registration in getTools() method, including name, description, and input schema requiring a numeric 'factor' parameter.
{ name: 'stretch', description: 'Time stretch pattern', inputSchema: { type: 'object', properties: { factor: { type: 'number', description: 'Stretch factor' } }, required: ['factor'] } }, - Input schema definition for the 'stretch' tool, specifying the required 'factor' as a number.
{ name: 'stretch', description: 'Time stretch pattern', inputSchema: { type: 'object', properties: { factor: { type: 'number', description: 'Stretch factor' } }, required: ['factor'] } }, - 'stretch' is listed in tools requiring initialization check.
