🔧 What Needs User Action

Required for First Use (30 minutes total)

#### 1. MIDI Device Setup (5-15 minutes)
macOS:
- Open Audio MIDI Setup
- Enable IAC Driver
- Verify "Device is online"

Windows:
- Download and install loopMIDI
- Create virtual port

Test:

python scripts/test_midi_connection.py

#### 2. Serato MIDI Learn (10-15 minutes)
- Open Serato DJ Pro
- Setup → MIDI → Enable virtual device
- Use MIDI Learn to map 5-10 Tier 0-3 actions
- Refer to: `docs/guides/SERATO_SETUP.md`

Test:

python scripts/test_serato_connection.py  # Keyboard mode

#### 3. Live Testing (YOUR TIME)
- Start full system:

  ./scripts/launch_full_studio.sh

• Load track in Serato
• Move (or simulate sensor input)
• Watch actions trigger on beats
• Monitor Tauri UI for telemetry

🚀 Quick Start Guide

Option 1: Test Keyboard Mode (Fastest)

# 1. Test keyboard connectivity
python scripts/test_serato_connection.py

# 2. If working, enable DJ Agent
# Already enabled in session.yaml!

# 3. Run engine
python scripts/run_studio.py

Option 2: Full MIDI Setup (Recommended)

# 1. Set up virtual MIDI (one-time)
# See docs/guides/SERATO_SETUP.md

# 2. Test MIDI connectivity
python scripts/test_midi_connection.py

# 3. Configure Serato MIDI Learn
# Map 5-10 actions in Serato

# 4. Launch full system
./scripts/launch_full_studio.sh

Option 3: Individual Components

# Engine only
python scripts/run_studio.py

# UI only
cd computational-studio/apps/desktop
npm run tauri dev

# SuperCollider only
sclang sound/supercollider/motion_synth.scd

### Phase 2: MIDI Mode
- [ ] Enable IAC Driver (macOS) or install loopMIDI (Windows)
- [ ] Run `python scripts/test_midi_connection.py`
- [ ] Verify MIDI port is visible
- [ ] Configure Serato MIDI Learn for 5-10 actions
- [ ] Test MIDI notes trigger Serato actions

### Phase 3: Full Integration
- [ ] Run `./scripts/launch_full_studio.sh`
- [ ] Verify Python engine starts (check `/tmp/studio_engine.log`)
- [ ] Verify Tauri UI starts and connects
- [ ] See DJ Agent panel in UI
- [ ] Watch phase wheel animate
- [ ] Load track in Serato

🐛 Known Issues & Limitations

### Current Limitations
1. No sensor input yet: Engine runs but needs actual sensor data or simulation
2. Beat detection: Phase tracking requires audio analysis or manual beat grid
3. MIDI latency: May vary by system (typically <5ms)
4. Keyboard mode: Requires Accessibility permission on macOS

### Not Yet Implemented (Future)
- [ ] Phase 5: Add DJ Agent controls to Tauri UI (tier toggles, mode switcher)
- [ ] Hardware controller integration (physical decks)
- [ ] Advanced RL training with recorded sessions
- [ ] Multi-deck support (>2 decks)
- [ ] Video export of training sessions
