Add Return Track and Mixing Controls to Ableton MCP #26
Conversation
WalkthroughThis update introduces extensive enhancements to the Ableton MCP system, focusing on advanced device parameter control, especially for audio effects and the EQ Eight device. The AbletonMCP Remote Script is expanded with unified track handling, new commands for creating return tracks, setting send levels, adjusting track volumes, and comprehensive device parameter manipulation. The MCP Server is updated to expose these capabilities via new API tools. Several detailed documentation files are added, outlining architecture, implementation, and usage. A suite of new test scripts is introduced to verify device control, EQ precision, send and volume control, browser/device management, and return track operations. The Changes

🔇 Additional comments (23)
.gitignore (1)
12-12: The addition of the 'docs' directory to .gitignore is appropriate.This change ensures that the documentation files added in this pull request, covering device parameter control and implementation details, are excluded from version control.
tests/volume_control_test.py (4)
18-49: Well-implemented robust JSON response handling.The
send_commandfunction correctly handles partial JSON responses by continuing to receive data until a complete, valid JSON object is received. This is a good pattern for socket communication.
106-111: Comprehensive volume levels testing.The test covers all essential volume points with meaningful descriptions:
- Muted (0.0)
- Half volume (-6dB)
- Unity gain (0dB)
- Maximum (+6dB)
This ensures proper validation of the linear-to-dB conversion functionality.
128-132: Good handling of special case for infinity representation.The code correctly formats "-∞ dB" for muted volume instead of showing the raw "-inf" value, which improves readability and user experience.
140-148: Proper error handling and resource cleanup.The script ensures the socket is properly closed even if an exception occurs, which is a good practice for resource management.
tests/send_control_test.py (4)
23-72: Robust command sending implementation.The
send_commandfunction provides comprehensive error handling:
- Creates and manages socket connections with context managers
- Handles incomplete JSON responses
- Properly formats and logs both commands and responses
- Catches and reports exceptions
This ensures reliable communication with the MCP server.
127-139: The calculation of return track index is correct.The code correctly calculates the track index for return tracks by adding the return track index to the total number of regular tracks. This approach aligns with how Ableton Live handles return track indexing.
141-191: Comprehensive send level testing with multiple values.The test covers the full range of send levels (0.0, 0.5, 1.0), ensuring that the
set_send_levelcommand works correctly at minimum, mid-range, and maximum values.
192-229: Well-structured test flow and result reporting.The main function provides:
- Clear connection verification
- Sequential test execution
- Comprehensive test summary with pass/fail indications
- Appropriate exit codes (0 for success, 1 for failure)
This structure makes the test results easy to interpret, both for manual execution and CI/CD integration.
tests/return_track_test.py (3)
73-109: Thorough return track creation verification.The test correctly:
- Gets initial return track count
- Creates a new return track
- Verifies that the count increased by exactly one
This approach properly validates that the
create_return_trackcommand works as expected.
192-237: Well-structured test execution and result reporting.The main function:
- Defines a list of tests to run
- Executes each test with exception handling
- Collects and reports results in a summary table
- Returns appropriate exit codes based on test results
This organization makes the test suite easy to maintain and extend with additional tests.
205-211: Good use of test collection for maintainability.Using a list of test function tuples allows for easy addition or removal of test cases without changing the core execution logic. This is a good practice for maintainable test suites.
docs/implementation_summary.md (3)
1-44: Well-structured implementation overview with appropriate architecture details.The implementation summary provides a clear, comprehensive explanation of the device parameter control system with well-organized sections detailing core functionality, EQ Eight specific features, and return track support capabilities. The document effectively communicates how these features work together.

tests/audio_effects_test.py (3)
18-74: Well-implemented socket communication pattern.The send_command function correctly handles socket communications with proper error handling, complete response collection, and JSON parsing. This is consistent with the pattern used in other test scripts, which is good for maintainability.
141-245: Robust parameter testing with proper validation.The test_device_parameters function is well-designed with:
- Comprehensive error handling
- Support for both discrete and continuous parameters
- Smart parameter selection logic
- Validation with appropriate tolerance for floating-point comparisons
This is a thorough implementation that will catch both obvious and subtle issues.
303-309: Good test isolation with separate tracks for each device.Creating a fresh test track for each device type is a solid testing practice that ensures tests don't interfere with each other. This approach increases reliability by preventing state from leaking between tests.
tests/browser_device_test.py (3)
77-96: Thorough browser tree testing with multiple category types.The test_get_browser_tree function effectively validates the get_browser_tree command with both default parameters and explicit category types. This ensures the command works across all supported category types.
148-153: Valuable implementation comments for maintainability.The comments explaining the underlying implementation details (that the server sends "load_browser_item" rather than "load_instrument_or_effect") provide excellent context for future developers. Similar helpful comments appear on lines 185-186 for the drum kit loading process.
163-234: Complete end-to-end test for drum kit loading.The test_load_drum_kit function thoroughly tests the complete workflow:
- Creating a track
- Loading the drum rack
- Browsing for available kits
- Selecting and loading a kit
This approach verifies not just individual commands but their interaction in a realistic usage scenario.

Return value must be JSON-serialisable string
FastMCP tools normally return a str. Returning a raw dict will cause FastAPI to attempt automatic JSON encoding which breaks the streaming/text-only contract and can confuse clients that expect plain text.

Track-volume setter lacks input validation
mixer_device.volume.value silently throws if given < 0 or > 1.
Rejecting or clamping the input prevents remote users from crashing the script.

Return-track index returned is inconsistent with the helper _get_track_by_index
_create_return_track() returns the index within self._song.return_tracks, but everywhere else in the API (e.g. _get_track_by_index) the caller is expected to treat track_index as the global index (regular_track_count + return_track_offset).
Mixing two index spaces will confuse clients and break round-tripping (create_return_track → get_track_info) because the latter expects the global index.

1258-1444: Well-designed preset system for EQ.The preset system provides a variety of common EQ configurations that can be easily applied with a single command.
1745-1771: Well-implemented volume unit conversion.The conversion from linear values to decibels correctly implements Ableton's non-linear volume curve, with appropriate handling of zero/near-zero values.

670-693:⚠️ Potential issueReturn value must be JSON-serializable string.
FastMCPtools should consistently return strings, but this function returns a raw dictionary that will cause FastAPI to attempt automatic JSON encoding, potentially breaking client expectations.Apply this change to maintain consistency with other API tools:
- return result + return json.dumps(result, indent=2)
1097-1118:⚠️ Potential issueAdd value validation to send_level setting.
The code correctly sets the send level but doesn't validate the input value range. This could lead to runtime errors in Live if values outside the valid range are provided.
Add value validation:
try: ableton = get_ableton_connection() + # Validate value range + if value < 0.0 or value > 1.0: + return f"Error: Send level value must be between 0.0 and 1.0" result = ableton.send_command("set_send_level", { "track_index": track_index, "send_index": send_index, "value": value })
1119-1145:⚠️ Potential issueAdd value validation to track volume setting.
Similar to the send level, this function should validate the input value range.
Add value validation:
try: ableton = get_ableton_connection() + # Validate value range + if value < 0.0 or value > 1.0: + return f"Error: Volume value must be between 0.0 and 1.0" result = ableton.send_command("set_track_volume", { "track_index": track_index, "value": value })Also, use a ternary operator for improved readability as suggested by static analysis:
- volume_db = result.get('volume_db', 'unknown') - if volume_db == float('-inf'): - volume_db_str = "-∞ dB" - else: - volume_db_str = f"{volume_db:.1f} dB" + volume_db = result.get('volume_db', 'unknown') + volume_db_str = "-∞ dB" if volume_db == float('-inf') else f"{volume_db:.1f} dB"🧰 Tools

505-523:⚠️ Potential issueReturn-track index returned is inconsistent with track index helper.
The
_create_return_track()returns the index withinself._song.return_tracks, but elsewhere in the API, track indices represent a unified space that includes both regular and return tracks.- # Get the new return track - new_return_track_index = len(self._song.return_tracks) - 1 - new_return_track = self._song.return_tracks[new_return_track_index] - - result = { - "index": new_return_track_index, + # Get the new return track + local_index = len(self._song.return_tracks) - 1 + global_index = len(self._song.tracks) + local_index + new_return_track = self._song.return_tracks[local_index] + + result = { + # Return the global index for consistency with API methods + "index": global_index, "name": new_return_track.name }
1690-1719:⚠️ Potential issueMissing validation in send level setter.
The implementation doesn't validate or clamp the input value to ensure it's within Ableton's expected range (0.0 to 1.0), which could cause runtime errors.
- # Verify the send index is valid - if send_index < 0 or send_index >= len(track.mixer_device.sends): + # Verify the send index is valid + if send_index < 0 or send_index >= len(track.mixer_device.sends): raise IndexError("Send index out of range") - # Get the send and set its value - send = track.mixer_device.sends[send_index] - send.value = value + # Validate value range + if value < 0.0 or value > 1.0: + raise ValueError("Send level must be between 0.0 and 1.0") + + send = track.mixer_device.sends[send_index] + send.value = valueAlso, ensure that

1720-1747:⚠️ Potential issueTrack-volume setter lacks input validation.
mixer_device.volume.valuesilently throws if given values outside the valid range. Validating inputs would prevent remote users from crashing the script.- # Set the volume value (0.0 to 1.0) - track.mixer_device.volume.value = value + # Validate & set volume (0.0 – 1.0) + if value < 0.0 or value > 1.0: + raise ValueError("Volume value must be between 0.0 and 1.0") + track.mixer_device.volume.value = value

1021-1162: Detailed EQ band parameter control.The implementation provides precise control over EQ band parameters with appropriate frequency normalization and handling of different filter types.
Consider adding direct validation for band_index rather than just using Value error:
- if band_index < 0 or band_index > 7: - raise ValueError("Band index must be between 0 and 7") + if not (0 <= band_index <= 7): + raise ValueError("Band index must be between 0 and 7")
1748-1774: Well-implemented volume-to-dB conversion.The
_linear_to_dbhelper provides an accurate conversion from Ableton's internal linear scale to meaningful decibel values, with appropriate handling of edge cases like silent/near-silent volumes.

🛠️ Refactor suggestion
Fix unused variables in EQ band parameter setting.
The function correctly implements detailed EQ band control with appropriate parameter conversion, but contains multiple unused variables flagged by static analysis.
Remove these unused variable assignments:
- freq_result = ableton.send_command("set_device_parameter", {
+ ableton.send_command("set_device_parameter", {
"track_index": track_index,
"device_index": device_index,
"parameter_name": freq_param_name,
"value": normalized_value
})
- gain_result = ableton.send_command("set_device_parameter", {
+ ableton.send_command("set_device_parameter", {
"track_index": track_index,
"device_index": device_index,
"parameter_name": gain_param_name,
"value": gain
})
- q_result = ableton.send_command("set_device_parameter", {
+ ableton.send_command("set_device_parameter", {
"track_index": track_index,
"device_index": device_index,
"parameter_name": q_param_name,

})
- filter_result = ableton.send_command("set_device_parameter", {
+ ableton.send_command("set_device_parameter", {
"track_index": track_index,
"device_index": device_index,
"parameter_name": filter_param_name,

})Also, line 769 contains an unnecessary f-string:
- return f"Error: Band index must be between 0 and 7"

1-2: Optional: Add repository link near the title
The title and badge clearly communicate the project’s purpose. For even quicker navigation, consider adding a hyperlink to the GitHub repository at the top (e.g., next to the title or badge).
10-15: Bullet list punctuation consistency
The feature list mixes punctuation styles (some items end with plain text, one ends with an exclamation). For uniformity, either remove the exclamation from “And much more!” or add consistent punctuation to all items.
80-80: Heading punctuation style
The heading “#### Step 6: Start Creating Music with AI!” ends with an exclamation mark, which conflicts with markdownlint MD026. Remove the “!” so it reads:#### Step 6: Start Creating Music with AI🧰 Tools
