📣 Updates

[2025-04-09]⚒️: It is no longer necessary to input MuseScore4 or mscore and the Python path. You only need to add the MuseScore4 or mscore installation directory (e.g., C:\Program Files\MuseScore 4\bin) to the system path environment variable.

[2025-03-21] ⚒️: Added more tunable parameters for more creative freedom. Optional model unloading.

[2025-03-15]⚒️: Supports Linux Ubuntu/Debian series, as well as servers, others untested, as well as servers.
