Option A: Strudel Integration - Implementation Status

## 🎯 Goal Wire existing Rust components (LIM-RPS, Rehearsal, Conductor) to Strudel.js for real-time pattern-based music generation controlled by body movement. ### 1. Comprehensive Codebase Analysis - ✅ Discovered **cc-core** contains full LIM-RPS implementation (Python/JAX) - ✅ Discovered **cc-brain** crate with Rehearsal and Conductor (Rust) - ✅ Confirmed **cc-protocol** Strudel-IR types are production-ready - ✅ Verified **audio-engine** with comprehensive synth library - ✅ Confirmed **echelon-tauri** desktop app is operational ### 2. Architecture Design - ✅ Created [STRUDEL_INTEGRATION_PLAN.md](./STRUDEL_INTEGRATION_PLAN.md) (full 10-day plan) - ✅ Designed Rust → JavaScript bridge via Tauri events - ✅ Specified PatternEdit command flow - ✅ Defined section-based pattern mapping strategy ### 3. StrudelEngine Implementation - ✅ Created [StrudelEngine.js](./apps/echelon-tauri/src/audio/StrudelEngine.js) - ✅ Implemented pattern parameter system (kick_gain, hihat_density, bass_cutoff, etc.) - ✅ Designed section-specific pattern templates: - Intro (sparse kick, minimal hats, ambient pads) - Groove (four-on-floor, offbeat snare, bass line) - Build (accelerating hats, rising bass, tension) - Climax (heavy kick, dense hats, driving bass) - Breakdown (no kick, emphasized pads, reverb) - Outro (fading elements) - ✅ Implemented `applyEdit()` method for: - SetParam (with optional transition_beats) - ScheduleEvent (with beat_offset and intensity) - Transform (track-specific transforms) - SectionChange (pattern template switching) **Files to modify**: 1. `apps/echelon-tauri/src-tauri/src/commands.rs` - Add `apply_pattern_edit()` command - Add `get_conductor_status()` command
