Hi, Here's my plan on how to front-port music streams to the 2.9 branch.
1. Implement classes Dispatcher, Stream_event, Listener (move modules from my thesis fork) 2. Add dispatchers event_source_, and possibly events_below_, to Context class. 3. Make Context::try_music send stream events to the event_source_. 4. Refactor certain iterators (apply-context, time-scaled-music), so that all music events are sent to bottom contexts. 5. Refactor commands such as lyricsto, to eliminate busy-playing-event etc. 6. There should now be no dependency on the try_music return value, so it should be safe to make Translator_group::try_music an event handler. 7. Add stream events for CreateContext, ChangeContext, Prepare, OneTimeStep, SetProperty, etc. These are quite easy to implement. 8. Various cleanups; e.g., remove the unneeded Score_context class.
