Member Function Documentation

clear_all_caches()

void zrythm::structure::arrangement::AutomationTimelineDataProvider::clear_all_caches ( )

overridevirtual

Implements zrythm::structure::arrangement::TimelineDataProvider.

generate_automation_events()

void zrythm::structure::arrangement::AutomationTimelineDataProvider::generate_automation_events ( const dsp::TempoMap & tempo_map, RangeOf< const arrangement::AutomationRegion * > auto automation_regions, utils::ExpandableTickRange affected_range )

inline

Generate the automation event sequence to be used during realtime processing.

To be called as needed from the UI thread when a new cache is requested.

Parameters

tempo_map	The tempo map for timing conversion.
automation_regions	The automation regions to process.
affected_range	The range of ticks to process.

get_automation_value_rt()

std::optional< float > zrythm::structure::arrangement::AutomationTimelineDataProvider::get_automation_value_rt ( units::sample_t sample_position )

noexcept

Get the automation value for a specific sample position.

Parameters

sample_position

The sample position to get the value for

Returns

The automation value at the given position, if any
