stop() → None[source]: Stop the playback worker.

update_tempo(new_tempo: int) → None[source]

update_tempo

Parameters:: new_tempo – int
Returns:: None

do_work() → None[source]: Process MIDI messages for playback.

_calculate_message_time(target_ticks: int) → float[source]: Calculate the time for a message at target_ticks using incremental tempo calculation. This correctly handles tempo changes by processing events in chronological order.
