From 6ad3cfab52e570f4cd5e7da02423d936fc06d00b Mon Sep 17 00:00:00 2001 From: Thomas Couderc Date: Tue, 18 Nov 2025 16:21:45 +0100 Subject: [PATCH 01/18] Add Device Variations API support for Live 12 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements comprehensive support for Ableton Live 12 Device Variations (Macro Variations) feature in AbletonOSC, enabling OSC control of rack variation states and parameters. ## Features Added ### Device API Extensions (abletonosc/device.py) - Properties (read-only): variation_count, can_have_chains, chains, has_macro_mappings, macros_mapped, visible_macro_count - Properties (read/write): selected_variation_index - Methods: recall_selected_variation(), recall_last_used_variation(), store_variation(), delete_selected_variation(), randomize_macros() - Introspection: /live/device/introspect endpoint for API discovery ### Scripts - introspect_device.py: Discovers available properties/methods on devices - explore_device_variations.py: Initial exploration script for variations - test_device_variations.py: Comprehensive test suite for variation APIs ### Documentation - DEVICE_VARIATIONS_PROPOSAL.md: Complete API documentation and implementation plan with test results ## Testing All core functionality tested successfully: - ✅ All read-only properties working - ✅ selected_variation_index read/write tested (index switching -1 → 0 → -1) - ✅ recall_* methods operational - ✅ Modification methods available (store, delete, randomize) ## Compatibility - Requires Ableton Live 12+ (variations feature introduced in Live 12) - Properties gracefully fail on non-RackDevice types - Backward compatible with Live 11 (properties return errors on unsupported devices) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .gitignore | 1 + DEVICE_VARIATIONS_PROPOSAL.md | 194 ++++++++++++++++++++++++++++ abletonosc/device.py | 78 +++++++++++- explore_device_variations.py | 129 +++++++++++++++++++ introspect_device.py | 177 ++++++++++++++++++++++++++ test_device_variations.py | 233 ++++++++++++++++++++++++++++++++++ 6 files changed, 811 insertions(+), 1 deletion(-) create mode 100644 DEVICE_VARIATIONS_PROPOSAL.md create mode 100755 explore_device_variations.py create mode 100755 introspect_device.py create mode 100755 test_device_variations.py diff --git a/.gitignore b/.gitignore index f66c226..80e63ed 100644 --- a/.gitignore +++ b/.gitignore @@ -2,3 +2,4 @@ *.swp __pycache__ .DS_Store +logs/ diff --git a/DEVICE_VARIATIONS_PROPOSAL.md b/DEVICE_VARIATIONS_PROPOSAL.md new file mode 100644 index 0000000..290b865 --- /dev/null +++ b/DEVICE_VARIATIONS_PROPOSAL.md @@ -0,0 +1,194 @@ +# Proposal: Device Variations API Support for AbletonOSC + +## Context + +**Device Variations** (also known as Macro Variations) were introduced in Ableton Live 12 and allow saving and recalling different parameter configurations for Instrument Racks and Effect Racks. + +This proposal aims to add support for variations in the AbletonOSC API. + +## Research Status + +### 🔍 Live 12 API Documentation + +After researching the Live Object Model (LOM) documentation for Live 12: +- ✅ Live 12 is already supported by AbletonOSC (automatically detected) +- ✅ Variations APIs were discovered through introspection +- ✅ Variations are exposed via `RackDevice` object properties + +### ✅ Introspection Results (2025-01-18) + +An introspection handler was added to `device.py` and the following properties/methods were discovered: + +#### Available Properties: +- ✅ `selected_variation_index`: Index of the active variation (-1 = none) +- ✅ `variation_count`: Number of available variations +- ✅ `can_have_chains`: Whether the device can have chains (racks) +- ✅ `chains`: List of chains in the rack +- ✅ `has_macro_mappings`: Whether the rack has macro mappings +- ✅ `macros_mapped`: Tuple indicating which macros are mapped +- ✅ `visible_macro_count`: Number of visible macros + +#### Available Methods: +- ✅ `recall_selected_variation()`: Recall the selected variation +- ✅ `recall_last_used_variation()`: Recall the last used variation +- ✅ `store_variation()`: Store current configuration as a variation +- ✅ `delete_selected_variation()`: Delete the selected variation +- ✅ `randomize_macros()`: Randomize macro values + +#### Available Listeners: +- ✅ `add_variation_count_listener()`: Listen to changes in variation count +- ✅ Plus all standard listeners for the properties above + +### 📋 Implemented OSC API ✅ + +The following endpoints have been implemented in `device.py`: + +#### Read-only Properties (Getters) + +| Endpoint | Params | Response | Description | +|----------|--------|----------|-------------| +| `/live/device/get/variation_count` | track_id, device_id | track_id, device_id, count | Number of available variations | +| `/live/device/get/can_have_chains` | track_id, device_id | track_id, device_id, bool | Whether device can have chains | +| `/live/device/get/has_macro_mappings` | track_id, device_id | track_id, device_id, bool | Whether rack has macro mappings | +| `/live/device/get/macros_mapped` | track_id, device_id | track_id, device_id, tuple | Tuple of mapped macros | +| `/live/device/get/visible_macro_count` | track_id, device_id | track_id, device_id, count | Number of visible macros | + +#### Read/Write Properties (Getters & Setters) + +| Endpoint | Params | Response/Action | Description | +|----------|--------|-----------------|-------------| +| `/live/device/get/selected_variation_index` | track_id, device_id | track_id, device_id, index | Index of active variation (-1 = none) | +| `/live/device/set/selected_variation_index` | track_id, device_id, index | -

Update your code to use the new paths. ### New API Structure **Properties:** - `/live/device/get/variations/num` (was: variation_count) - `/live/device/get/variations/selected` (was: selected_variation_index) - `/live/device/set/variations/selected` (was: set/selected_variation_index) **Listeners:** - `/live/device/start_listen/variations/num` - `/live/device/start_listen/variations/selected` - (and corresponding stop_listen endpoints) **Methods:** - `/live/device/variations/recall` (was: recall_selected_variation) - `/live/device/variations/recall_last` (was: recall_last_used_variation) - `/live/device/variations/store` (was: store_variation) - `/live/device/variations/delete` (was: delete_selected_variation) - `/live/device/variations/randomize` (was: randomize_macros) ### Rationale - Follows existing AbletonOSC pattern: `/live/track/get/num_devices` - Groups related endpoints under `/variations/` namespace - Removes redundant suffixes (`_index`, `_variation`, `_macros`) - More intuitive: `variations/num` vs `variation_count` - Consistent with hierarchical OSC structure ### Changes - **abletonosc/device.py**: Refactored all variation handlers with new paths - **tests/test_device.py**: Updated all test cases with new API paths - **run-console.py**: Updated autocomplete with new paths - **README.md**: Updated documentation with new API structure - **pytest.ini**: Added to exclude devel/ from test discovery 🤖 Generated with [Claude Code](https://claude.com/claude-code)

Removed development-specific ignores from .gitignore (logs/, devel/*) - Removed all "Live 12+" mentions (assumed majority of users on Live 12+) - Improved introspection output: lowercase keys for consistency - Enhanced comments: explained string length limit for OSC message size **Tests:** - Uncommented destructive tests (store/delete variations) - Tests are expected to be run on non-production sets - Now includes full test coverage: 10 tests total **Documentation:** - Removed redundant start_listen/stop_listen entries from README - Simplified variation descriptions (removed "Live 12+" mentions) - Kept only essential documentation **Introspection Improvements:** - Changed "PROPERTIES:" to "properties:" for consistency - Changed "METHODS:" to "methods:" for consistency - Added detailed comment explaining string truncation rationale All feedback addressed while keeping devel/introspect.py for maintainer review. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- .gitignore | 3 -- README.md | 22 +++++------- abletonosc/device.py | 12 ++++--- tests/test_device.py | 81 +++++++++++++++++++++----------------------- 4 files changed, 55 insertions(+), 63 deletions(-) diff --git a/.gitignore b/.gitignore index 87c5e1b..f66c226 100644 --- a/.gitignore +++ b/.gitignore @@ -2,6 +2,3 @@ *.swp __pycache__ .DS_Store -logs/ -devel/* -!devel/introspect.py diff --git a/README.md b/README.md index 7399018..1b9680e 100644 --- a/README.md +++ b/README.md @@ -495,23 +495,19 @@ Represents an instrument or effect. | /live/device/get/parameter/value | track_id, device_id, parameter_id | track_id, device_id, parameter_id, value | Get a device parameter value | | /live/device/get/parameter/value_string | track_id, device_id, parameter_id | track_id, device_id, parameter_id, value | Get the device parameter value as a readable string ex: 2500 Hz | | /live/device/set/parameter/value | track_id, device_id, parameter_id, value | | Set a device parameter value | -| /live/device/get/variations/num | track_id, device_id | track_id, device_id, count | Get the number of variations (Live 12+, RackDevice only) | -| /live/device/get/variations/selected | track_id, device_id | track_id, device_id, index | Get the selected variation index, -1 if none (Live 12+, RackDevice only) | -| /live/device/set/variations/selected | track_id, device_id, index | | Select a variation by index (Live 12+, RackDevice only) | -| /live/device/start_listen/variations/num | track_id, device_id | | Start listening for variation count changes (Live 12+, RackDevice only) | -| /live/device/stop_listen/variations/num | track_id, device_id | | Stop listening for variation count changes (Live 12+, RackDevice only) | -| /live/device/start_listen/variations/selected| track_id, device_id | | Start listening for selected variation changes (Live 12+, RackDevice only) | -| /live/device/stop_listen/variations/selected | track_id, device_id | | Stop listening for selected variation changes (Live 12+, RackDevice only) | +| /live/device/get/variations/num | track_id, device_id | track_id, device_id, count | Get the number of variations (RackDevice only) | +| /live/device/get/variations/selected | track_id, device_id | track_id, device_id, index | Get the selected variation index, -1 if none (RackDevice only) | +| /live/device/set/variations/selected | track_id, device_id, index | | Select a variation by index (RackDevice only) | ### Device methods | Address | Query params | Response params | Description | |:------------------------------------------|:--------------------|:----------------|:---------------------------------------------------------------| -| /live/device/variations/recall | track_id, device_id | | Apply the selected variation's macro values (Live 12+, RackDevice only) | -| /live/device/variations/recall_last | track_id, device_id | | Recall the last used variation (Live 12+, RackDevice only) | -| /live/device/variations/store | track_id, device_id | | Store current macro values as a new variation (Live 12+, RackDevice only) | -| /live/device/variations/delete | track_id, device_id | | Delete the currently selected variation (Live 12+, RackDevice only) | -| /live/device/variations/randomize | track_id, device_id | | Randomize all macro values in the rack (Live 12+, RackDevice only) | +| /live/device/variations/recall | track_id, device_id | | Apply the selected variation's macro values (RackDevice only) | +| /live/device/variations/recall_last | track_id, device_id | | Recall the last used variation (RackDevice only) | +| /live/device/variations/store | track_id, device_id | | Store current macro values as a new variation (RackDevice only) | +| /live/device/variations/delete | track_id, device_id | | Delete the currently selected variation (RackDevice only) | +| /live/device/variations/randomize | track_id, device_id | | Randomize all macro values in the rack (RackDevice only) | | /live/device/introspect | track_id, device_id | properties, methods | List all available properties and methods for the device | For devices: @@ -520,7 +516,7 @@ For devices: -

Fixed case-sensitivity bug in response parsing - Server returns lowercase markers ("properties:", "methods:") - Client was checking for uppercase ("PROPERTIES:", "METHODS:") - This caused all introspection results to appear empty 2. Made keyword highlighting generic and optional - Removed hardcoded keywords (variation, macro, chain, etc.) - Added optional --highlight CLI parameter for user-specified keywords - Tool now remains generic for any Live API introspection - Example: ./devel/introspect.py device 0 0 --highlight variation,macro This ensures the introspection tool is feature-agnostic and usable for discovering any Live object API, not just device variations. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- devel/introspect.py | 61 +++++++++++++++++++++++++++++---------------- 1 file changed, 40 insertions(+), 21 deletions(-) diff --git a/devel/introspect.py b/devel/introspect.py index e9372ae..b7f327c 100755 --- a/devel/introspect.py +++ b/devel/introspect.py @@ -64,8 +64,15 @@ def find_free_port(start_port=11001, max_attempts=10): continue return None -def format_introspection_output(result, object_type, object_ids): -

If a RackDevice exists but has no variations, automatically create 2 test variations - Store current macro state as variation 1 - Randomize macros and store as variation 2 - Clean up auto-created variations after tests complete using pytest yield pattern This eliminates the need for manual variation setup - users only need to add a RackDevice to track 0 and tests will handle the rest. Also adjusted test_track_devices to check track 1 instead of track 0 to avoid conflict with Device Variations tests that use track 0. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- tests/test_device.py | 68 +++++++++++++++++++++++++++++++++++++++----- tests/test_track.py | 2 +- 2 files changed, 62 insertions(+), 8 deletions(-) diff --git a/tests/test_device.py b/tests/test_device.py index a179d31..2717535 100644 --- a/tests/test_device.py +++ b/tests/test_device.py @@ -5,8 +5,8 @@ # Device Variations tests # # To test variations: -# 1.
