| Summary | 0009957: Broken OSC Plugin Parameter Handling | ||||
| Description | Ardour Version is: Ardour 8.4.0~ds1-2ubuntu8 TLDR; I try to query the control values of plugins. I have an Ardour session with 32 channels, each with IEM Stereo Encoder plugin on index 1, i.e. the one and only plugin in each channelstrip. OSC feedback is set to 3 . I am developing a JUCE application with liblo OSC Backend (since JUCE can't handle #reply). | ||||
| Steps To Reproduce | The control flow of my application is as follows: ############################################################ 1. Query '/strip/list' and parse the replies 2. Query '/strip/plugin/list' to get the list of plugins for each strip. 3. Query '/strip/plugin/descriptor' to find the correct control. 4. Query '/strip/plugin/parameter' to get the current value of the control. I see the following log output in Ardour: ############################################################# 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/list i:19 i:1 2025-07-20T10:31:01 [INFO]: OSC: /strip/plugin/descriptor i:19 i:1 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:0 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:1 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:2 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:3 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:4 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:5 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:6 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:7 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:8 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:9 2025-07-20T10:31:01 [INFO]: Unhandled OSC message: /strip/plugin/parameter i:19 i:1 i:10 | ||||
