|
||||
## D. Failures and Fixes
|
||||
|
||||
### D.1 Initial Failure: `get_clips` Not Found
|
||||
|
||||
**Error:** `[ERROR:ABLETON_ERROR] Unknown command: get_clips`
|
||||
|
||||
**Root Cause:** Command routing was placed AFTER the main thread task block, causing it to never be reached.
|
||||
|
||||
**Fix:** Moved `get_clips`, `get_clip_info`, and `get_devices` routing to the direct command handling section (before main thread tasks).
|
||||
|
||||
**File:** `abletonmcp_init.py` lines 248-262
|
||||
|
||||
**Status:** ✅ Fixed and verified
|
||||
|
||||
---
|
||||
|
||||
### D.2 Initial Failure: `create_arrangement_clip` Not Materialized
|
||||
|
||||
**Error:** `[ERROR:ABLETON_ERROR] Arrangement clip was not materialized`
|
||||
|
||||
**Root Cause:**
|
||||
1. Track object lacks `create_clip()` method in this Ableton version
|
||||
2. Session-to-Arrangement recording fallback timing was too short
|
||||
3. `_locate_arrangement_clip()` couldn't find the clip after recording
|
||||
|
||||
**Fix:** Used alternative workflow:
|
||||
1. Create clip in Session View (`create_clip`)
|
||||
2. Add notes to Session clip (`add_notes_to_clip`)
|
||||
3. Duplicate to Arrangement (`duplicate_clip_to_arrangement`)
|
||||
|
||||
**Status:** ✅ Bypassed via Session fallback workflow
|
||||
|
||||
---
|
||||
|
||||
### D.3 Initial Failure: `string_types` Not Defined
|
||||
|
||||
**Error:** `name 'string_types' is not defined`
|
||||
|
||||
**Root Cause:** Missing Python 2/3 compatibility definition for `string_types`.
|
||||
|
||||
**Fix:** Added at line 13:
|
||||
```python
|
||||
try:
|
||||
string_types = basestring # Python 2
|
||||
except NameError:
|
||||
string_types = str # Python 3
|
||||
```
|
||||
|
||||
**File:** `abletonmcp_init.py` lines 13-16
|
||||
|
||||
**Status:** ✅ Fixed and verified
|
||||
|
||||

|
||||
|
||||
## E. Reviewer-Grade Conclusion
|
||||
|
||||
### Status: **COMPLETED**
|
||||
|
||||
All P0 tasks validated on the live benchmark project:
|
||||
|
||||
| P0 Task | Status |
|
||||
|---------|--------|
|
||||
| P0.1 - Restart and validate runtime | ✅ PASS |
|
||||
| P0.2 - Inspection tools on song.als | ✅ PASS |
|
||||
| P0.3 - Arrangement MIDI editing | ✅ PASS (via Session fallback) |
|
||||
| P0.4 - set_device_parameter by name | ✅ PASS |
|
||||
| P0.5 - audit_current_project | ✅ PASS |
|
||||
|
||||
### Evidence Summary
|
||||
|
||||
- ✅ MCP connects to Ableton Live
|
||||
- ✅ `get_clips` returns real clip data from song.als
|
||||
- ✅ `get_devices` returns device info
|
||||
- ✅ MIDI clips can be created and added to Arrangement
|
||||
- ✅ Device parameters can be changed by name
|
||||
- ✅ `audit_current_project` detects gaps, empty tracks, and overuse
|
||||
|
||||
### What Changed in song.als
|
||||
|
||||
1. HARMONY_PIANO_MIDI now has 1 arrangement clip with 6 MIDI notes
|
||||
2. Wavetable device Transpose parameter changed to 0.50
|
||||
|
||||
### Files Modified
|
||||
|
||||
| File | Changes |
|
||||
|------|---------|
|
||||
| `abletonmcp_init.py` | Fixed `get_clips` routing, added `string_types` definition |
|
||||
|
||||
---
|
||||
|
||||
## F. Known Limitations
|
||||
|
||||
1. **Direct Arrangement clip creation** requires Session fallback on tracks without `create_clip()` method
|
||||
2. **Parameter name matching** is case-insensitive but requires exact parameter name from Live
|
||||
3. **`get_device_parameters`** fails on non-quantized parameters
|
||||
|
||||
---
|
||||
|
||||
## G. Next Steps
|
||||
|
||||
### P1.1 - Improve `get_clip_info` Semantics
|
||||
|
||||
Current state: Session-slot-centric
|
||||
Recommendation: Add `view` parameter to distinguish Session vs Arrangement clips
|
||||
|
||||
### P1.2 - Design Safe Editing Orchestration
|
||||
|
||||
After P0 proven working, consider adding `refine_existing_song()` orchestration tool.
